This patch will present the structure for the NVMeTCP offload common
layer driver. This module is added under "drivers/nvme/host/" and future
offload drivers which will register to it will be placed under
"drivers/nvme/hw".
This new driver will be enabled by the Kconfig "NVM Express over Fabrics
TCP offload commmon layer".
In order to support the new transport type, for host mode, no change is
needed.
Each new vendor-specific offload driver will register to this ULP during
its probe function, by filling out the nvme_tcp_ofld_dev->ops and
nvme_tcp_ofld_dev->private_data and calling nvme_tcp_ofld_register_dev
with the initialized struct.
The internal implementation:
- tcp-offload.h:
Includes all common structs and ops to be used and shared by offload
drivers.
- tcp-offload.c:
Includes the init function which registers as a NVMf transport just
like any other transport.

iwl-next Intel Wired LAN Driver Updates 2021-06-01
This pull request is targeting net-next and rdma-next branches.
These patches have been reviewed by netdev and rdma mailing lists[1].
This series adds RDMA support to the ice driver for E810 devices and
converts the i40e driver to use the auxiliary bus infrastructure
for X722 devices. The PCI netdev drivers register auxiliary RDMA devices
that will bind to auxiliary drivers registered by the new irdma module.

Pull xfs fixes from Darrick Wong:
"This week's pile mitigates some decades-old problems in how extent
size hints interact with realtime volumes, fixes some failures in
online shrink, and fixes a problem where directory and symlink
shrinking on extremely fragmented filesystems could fail.
The most user-notable change here is to point users at our (new) IRC
channel on OFTC. Freedom isn't free, it costs folks like you and me;
and if you don't kowtow, they'll expel everyone and take over your

Adds the sun6i_hwspinlock driver for the hardware spinlock unit found in
most of the sun6i compatible SoCs.
This unit provides at least 32 spinlocks in hardware. The implementation
supports 32, 64, 128 or 256 32bit registers. A lock can be taken by
reading a register and released by writing a 0 to it. This driver
supports all 4 spinlock setups, but for now only the first setup (32
locks) seem to exist in available devices. This spinlock unit is shared
between all ARM cores and the embedded companion core. All of them can
take/release a lock with a single cycle operation. It can be used to
sync access to devices shared by the ARM cores and the companion core.
There are two ways to check if a lock is taken. The first way is to read
a lock. If a 0 is returned, the lock was free and is taken now. If an 1
is returned, the caller has to try again. Which means the lock is taken.
The second way is to read a 32bit wide status register where every bit
represents one of the 32 first locks. According to the datasheets this
status register supports only the 32 first locks. This is the reason the
first way (lock read/write) approach is used to be able to cover all 256
locks in future devices. The driver also reports the amount of supported
locks via debugfs.

The Arm FF for Armv8-A specification has concept of endpoints or
partitions. In the Normal world, a partition could be a VM when
the Virtualization extension is enabled or the kernel itself.
In order to handle multiple partitions, we can create a FFA device for
each such partition on a dedicated FFA bus. Similarly, different drivers
requiring FFA transport can be registered on the same bus. We can match
the device and drivers using UUID. This is mostly for the in-kernel
users with FFA drivers.

NXP's TFA98xx (now part of Goodix) are fairly popular speaker amplifiers
used in many smartphones and tablets. Most of them are sold as "smart
amplifiers" with built-in "CoolFlux DSP" that is used for volume control,
plus a "sophisticated speaker-boost and protection algorithm".
Unfortunately, they are also almost entirely undocumented. The short
datasheets (e.g. [1] for TFA9897) describe the available features,
but do not provide any information about the registers or how to use
the "CoolFlux DSP".
The amplifiers are most often configured through proprietary userspace
libraries. There are also some (rather complex) kernel drivers (e.g. [2])
but even those rely on obscure firmware blobs for configuration (so-called
"containers"). They seem to contain different "profiles" with tuned speaker
settings, sample rates and volume steps (which would be better exposed
as separate ALSA mixers).
The format of the firmware files seems to have changed a lot over the time,
so it's not even possible to simply re-use the firmware originally provided
by the vendor.
Overall, it seems close to impossible to develop a proper mainline driver
for these amplifiers that could make proper use of the built-in DSP.
This commit implements a compromise: At least the TFA1 family of the
TFA98xx amplifiers (usually called TFA989x) provide a way to *bypass*
the DSP using a special register sequence. The register sequence can be
found in similar variations in the kernel drivers from lots of vendors
e.g. in [3] and was probably mainly used for factory testing.
With the DSP bypassed, the amplifier acts mostly like a dumb standard
speaker amplifier, without (hardware) volume control. However, the setup
is much simpler and it works without any obscure firmware.
This driver implements the DSP bypass combined with chip-specific
initialization sequences adapted from [2]. Only TFA9895 is supported in
this initial commit. Except for the lack of volume control I can not hear
any difference with or without the DSP, it works just fine.
This driver allows the speaker to work on mainline Linux running on the
Samsung Galaxy A3/A5 (2015) [TFA9895] and Alcatel Idol 3 [TFA9897].
TFA9897 support will be added in separate patch set later.

An early prototypical automated code analysis of headers and the
existing MAINTAINERS sections identified some header files in
./include/linux/ to be probably included into the TTY LAYER section.
I further checked those suggestions by this analysis and identified a
subset of files that I am rather certain to belong to the TTY LAYER.
Add these ./include/linux/ header files to TTY LAYER in MAINTAINERS.
The patterns include/linux/tty*.h and include/linux/vt_*.h currently cover:
include/linux/tty.h
include/linux/tty_driver.h
include/linux/tty_flip.h

Basically the TI TSC2046 touchscreen controller is 8 channel ADC optimized for
the touchscreen use case. By implementing it as an IIO ADC device, we can
make use of resistive-adc-touch and iio-hwmon drivers.
Polled readings are currently not implemented to keep this patch small, so
iio-hwmon will not work out of the box for now.
So far, this driver was tested with a custom version of resistive-adc-touch driver,
since it needs to be extended to make use of Z1 and Z2 channels. The X/Y
are working without additional changes.

moving to nvdimm@lists.linux.dev.
The old list will remain up until v5.14-rc1 and shutdown thereafter.

Pull Landlock LSM from James Morris:
"Add Landlock, a new LSM from Mickaël Salaün.
Briefly, Landlock provides for unprivileged application sandboxing.
From Mickaël's cover letter:
"The goal of Landlock is to enable to restrict ambient rights (e.g.
global filesystem access) for a set of processes. Because Landlock
is a stackable LSM [1], it makes possible to create safe security
sandboxes as new security layers in addition to the existing
system-wide access-controls. This kind of sandbox is expected to
help mitigate the security impact of bugs or unexpected/malicious
behaviors in user-space applications. Landlock empowers any
process, including unprivileged ones, to securely restrict
themselves.
Landlock is inspired by seccomp-bpf but instead of filtering
syscalls and their raw arguments, a Landlock rule can restrict the
use of kernel objects like file hierarchies, according to the
kernel semantic. Landlock also takes inspiration from other OS
sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD
Pledge/Unveil.
In this current form, Landlock misses some access-control features.
This enables to minimize this patch series and ease review. This
series still addresses multiple use cases, especially with the
combined use of seccomp-bpf: applications with built-in sandboxing,
init systems, security sandbox tools and security-oriented APIs [2]"
The cover letter and v34 posting is here:
https://lore.kernel.org/linux-security-module/20210422154123.13086-1-mic@digikod.net/

The simpledrm driver is a DRM driver for simple-framebuffer framebuffers
as provided by the kernel's boot code. This driver enables basic
graphical output on many different graphics devices that are provided
by the platform (e.g., EFI, VESA, embedded framebuffers).
With the kernel's simple-framebuffer infrastructure, the kernel receives
a pre-configured framebuffer from the system (i.e., firmware, boot
loader). It creates a platform device to which simpledrm attaches.
The system's framebuffer consists of a memory range, size and format.
Based on these values, simpledrm creates a DRM devices. No actual
modesetting is possible.
A firmware framebuffer might also be specified via device-tree files. If
no device platform data is given, try the DT device node.
Make sure required hardware clocks and regulators are enabled while the
firmware framebuffer is in use. The basic code has been taken from the
simplefb driver and adapted to DRM. Clocks are released automatically
via devres helpers.
The drivers displays a console on simpledrm's framebuffer. The default
framebuffer format is being used.
v4:
* disable simplefb if simpledrm has been selected (Maxime)
v3:
* add disable function that clears screen to black (Daniel)
* set shadow buffering only for fbdev emulation
* set platform-driver data during device creation
v2:
* rename driver to simpledrm
* add dri-devel to MAINTAINERS entry
* put native format first in primary-plane format list (Daniel)
* inline simplekms_device_cleanup() (Daniel)
* use helpers for shadow-buffered planes
* fix whitespace errors
* add Device Tree match table
* clean-up parser wrappers
* use strscpy()

Core changes:
- A semantic change to handle pinmux and pinconf in explicit order
while up until now we depended on the semantic order in the
device tree. The device tree is a functional programming
language and does not imply any order, so the right thing is
for the pin control core to provide these semantics.
- Add a new pinmux-select debugfs file which makes it possible to
go in and select functions for a pin manually (iteratively, at
the prompt) for debugging purposes.
- Fixes to gpio regmap handling for a new pin control driver
making use of regmap-gpio.
- Use octal permissions on debugfs files.
New drivers:
- A massive rewrite of the former custom pin control driver for
MIPS Broadcom devices to instead use the pin control subsystem.
New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362,
BCM6368, BCM63268 and BCM6318 SoC variants are implemented.
- Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and
PMR735B in the Qualcomm PMIC GPIO driver. Also the two GPIOs
on PM8008 are supported.
- Support for the Rockchip RK3568/RK3566 pin controller.
- Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and
X2000.
- Support for Mediatek MTK8195.
- Add a new Xilinx ZynqMP pin control driver.
Driver improvements and non-urgent fixes:
- Modularization and improvements of the Rockchip drivers.
- Some new pins added to the description of new Renesas SoCs.
- Clarifications of the GPIO base calculation in the Intel driver.
- Fix the function names for the MPP54 and MPP55 pins in the Armada
CP110 pin controller.
- GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.
- Support for ACPI probing of the Qualcomm SC8180x.
- Fix interrupt clear status on rockchip
- Fix some missing pins on the Ingenic JZ4770, some semantic
fixes for the behaviour of the Ingenic pin controller.
Add DMIC pins for JZ4780, X1000, X1500 and X1830.
- A slew of janitorial like of_node_put() calls.

No surprises in this development cycle, and most of works are about
the fixes and the improvements of the existing code, while a new LED
control layer and a few new drivers have been introduced.
Here are some highlights:
Core:
- A common mute-LED framework was introduced;
used by HD-audio for now, more adaption will follow later.
The former "Mic Mute-LED Mode" mixer control has been replaced with
the corresponding sysfs now.
- User-control management was changed to count consumed bytes instead
of capping by number of elements;
this will allow more controls in the normal usage pattern while
avoiding the possible memory exhaustion DoS
ASoC:
- Continued refactoring and cleanups in ASoC core and generic card
drivers
- Wide range of small cppcheck and warning fixes
- New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
accessory detection, and Realtek RT1019, RT1316, RT711 and RT715
USB-audio:
- Continued improvements and fixes of the implicit feedback mode,
including better support for Pioneer and Roland/BOSS devices
HD-audio:
- Default back to non-buffer preallocation on x86
- Cirrus codec improvements, more quirks for Realtek codecs
Others:
- New virtio sound driver
- FireWire Bebob updates
Note that this PR includes a couple of changes in reset and SPI
drivers, too, and some merge conflicts might happen.

Patch series "kernel-doc and MAINTAINERS clean-up".
Roughly 900 warnings of about 21.000 kernel-doc warnings in the kernel
tree warn with 'cannot understand function prototype:', i.e., the
kernel-doc parser cannot parse the function's signature. The majority,
about 600 cases of those, are just struct definitions following the
kernel-doc description. Further, spot-check investigations suggest that
the authors of the specific kernel-doc descriptions simply were not
aware that the general format for a kernel-doc description for a
structure requires to prefix the struct name with the keyword 'struct',
as in 'struct struct_name - Brief description.'. Details on kernel-doc
are at the Link below.
Without the struct keyword, kernel-doc does not check if the kernel-doc
description fits to the actual struct definition in the source code.
Fortunately, in roughly a quarter of these cases, the kernel-doc
description is actually complete wrt. its corresponding struct
definition. So, the trivial change adding the struct keyword will allow
us to keep the kernel-doc descriptions more consistent for future
changes, by checking for new kernel-doc warnings.
Also, some of the files in ./include/ are not assigned to a specific
MAINTAINERS section and hence have no dedicated maintainer. So, if
needed, the files in ./include/ are also assigned to the fitting
MAINTAINERS section, as I need to identify whom to send the clean-up
patch anyway.
Here is the change from this kernel-doc janitorial work in the
./include/ directory for MEMORY MANAGEMENT.
This patch (of 2):
Commit a520110e4a ("mm: split out a new pagewalk.h header from mm.h")
adds a new file in ./include/linux, but misses to update MAINTAINERS
accordingly. Hence,
./scripts/get_maintainers.pl include/linux/pagewalk.h
points only to lkml as general fallback for all files, whereas the
original include/linux/mm.h clearly marks this file part of MEMORY
MANAGEMENT.
Assign include/linux/pagewalk.h to MEMORY MANAGEMENT.

Core:
- bpf:
- allow bpf programs calling kernel functions (initially to
reuse TCP congestion control implementations)
- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM
- add bpf_for_each_map_elem() helper, allowing programs to
walk all map elements in a more robust and easier to verify
fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection
- lpm: add support for batched ops in LPM trie
- add BTF_KIND_FLOAT support - mostly to allow use of BTF
on s390 which has floats in its headers files
- improve BPF syscall documentation and extend the use of kdoc
parsing scripts we already employ for bpf-helpers
- libbpf, bpftool: support static linking of BPF ELF files
- improve support for encapsulation of L2 packets
- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks
- xsk: build skb by page (aka generic zerocopy xmit) - improve
performance of software AF_XDP path by 33% for devices
which don't need headers in the linear skb part (e.g. virtio)
- nexthop: resilient next-hop groups - improve path stability
on next-hops group changes (incl. offload for mlxsw)
- ipv6: segment routing: add support for IPv4 decapsulation
- icmp: add support for RFC 8335 extended PROBE messages
- inet: use bigger hash table for IP ID generation
- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is
slow in reporting that it completed transmitting the original
- tcp: reorder tcp_congestion_ops for better cache locality
- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR
- add reset option support for resetting one subflow
- udp: GRO L4 improvements - improve 'forward' / 'frag_list'
co-existence with UDP tunnel GRO, allowing the first to take
place correctly even for encapsulated UDP traffic
- micro-optimize dev_gro_receive() and flow dissection, avoid
retpoline overhead on VLAN and TEB GRO
- use less memory for sysctls, add a new sysctl type, to allow using
u8 instead of "int" and "long" and shrink networking sysctls
- veth: allow GRO without XDP - this allows aggregating UDP
packets before handing them off to routing, bridge, OvS, etc.
- allow specifing ifindex when device is moved to another namespace
- netfilter:
- nft_socket: add support for cgroupsv2
- nftables: add catch-all set element - special element used
to define a default action in case normal lookup missed
- use net_generic infra in many modules to avoid allocating
per-ns memory unnecessarily
- xps: improve the xps handling to avoid potential out-of-bound
accesses and use-after-free when XPS change race with other
re-configuration under traffic
- add a config knob to turn off per-cpu netdev refcnt to catch
underflows in testing
Device APIs:
- add WWAN subsystem to organize the WWAN interfaces better and
hopefully start driving towards more unified and vendor-
-independent APIs
- ethtool:
- add interface for reading IEEE MIB stats (incl. mlx5 and
bnxt support)
- allow network drivers to dump arbitrary SFP EEPROM data,
current offset+length API was a poor fit for modern SFP
which define EEPROM in terms of pages (incl. mlx5 support)
- act_police, flow_offload: add support for packet-per-second
policing (incl. offload for nfp)
- psample: add additional metadata attributes like transit delay
for packets sampled from switch HW (and corresponding egress
and policy-based sampling in the mlxsw driver)
- dsa: improve support for sandwiched LAGs with bridge and DSA
- netfilter:
- flowtable: use direct xmit in topologies with IP
forwarding, bridging, vlans etc.

usual suspects are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and
Rockchip, but it feels pretty light on commits. There's only one real commit to
the framework core and that's to consolidate code. Otherwise the diffstat is
dominated by many Qualcomm clk driver patches that modernize the driver for the
proper way of speciying clk parents. That's shifting data around, which could
subtly break things so I'll be on the lookout for fixes.
New Drivers:
- Proper clk driver for Mediatek MT7621 SoCs
- Support for the clock controller on the new Rockchip rk3568
Updates:
- Simplify Zynq Kconfig dependencies
- Use clk_hw pointers in socfpga driver
- Cleanup parent data in qcom clk drivers
- Some cleanups for rk3399 modularization
- Fix reparenting of i.MX UART clocks by initializing only the ones
associated to stdout
- Correct the PCIE clocks for i.MX8MP and i.MX8MQ
- Make i.MX LPCG and SCU clocks return on registering failure
- Kernel doc fixes
- Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N
- Add timer (TMU) clocks on Renesas R-Car H3 ES1.0
- Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on Renesas R-Car V3U

Pull printk updates from Petr Mladek:
- Stop synchronizing kernel log buffer readers by logbuf_lock. As a
result, the access to the buffer is fully lockless now.
Note that printk() itself still uses locks because it tries to flush
the messages to the console immediately. Also the per-CPU temporary
buffers are still there because they prevent infinite recursion and
serialize backtraces from NMI. All this is going to change in the
future.
- kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
removal.
- Make bstr_printf() aware that %pf and %pF formats could deference the
given pointer.
- Show also page flags by %pGp format.
- Clarify the documentation for plain pointer printing.
- Do not show no_hash_pointers warning multiple times.
- Update Senozhatsky email address.
- Some clean up.

The only core work for SPI this time around is the completion of the
conversion to the new style method for specifying transfer delays,
meaning we can cope with what most controllers support more directly
using conversions in the core rather than open coding in drivers.
Otherwise it's a good stack of cleanups and fixes plus a few new
drivers.
The conversion to new style transfer delay will cause an issue with a
newly added staging driver which has a straightforward resolution in
-next.
- Completion of the conversion to new style transfer delay
configuration.
- Introduction and use of module_parport_driver() helper, merged here
as there's no parport tree.
- Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng,
MediaTek MT8195,

The most notable change is the removal of the amd_energy driver. It was
rendered all but unusable by making its attributes privileged-only to work
around a security issue. A suggested remedy was rejected by AMD, so the
only real solution was to remove the driver. For the future, we'll have
to make sure that no privileged-access-only drivers are accepted into the
hwmon subsystem in the first place. The hwmon ABI document was updated
accordingly.
Other changes:
PMBus drivers:
- Added driver for MAX15301
- Added driver for BluTek BPA-RS600
- Added driver for fsp-3y PSUs and PDUs
- Added driver for Infineon IR36021
- Added driver for ST STPDDC60
- Added support for TI TPS53676 to tps53679 driver
- Introduced PMBUS symbol namespace
This was made necessary by a suggestion to use its exported functions
from outside the hwmon subsystem.
- Minor improvements and bug fixes
New drivers:
- Driver for NZXT Kraken X42/X52/X62/X72
Driver enhancements:
- Added support for Intel D5005 to intel-m10-bmc-hwmon driver
- Added support for NCT6686D to nct6683 driver
Other:
- Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info()
- Added support for fan drawers capability and present registers to mlxreg-fan
driver
- Added Dell Latitude E7440 to fan control whitelist in dell-smm driver
- Replaced snprintf in show functions with sysfs_emit
Done with coccinelle script for all drivers to preempt endless per-driver
submissions of the same change.
- Use kobj_to_dev()
Another coccinelle based change to preempt endless per-driver submissions
of the same change.
- Various minor fixes and improvements

but it boots and can use framebuffer and serial console over a special
USB cable.
Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe)

The Nuvoton WPCM450 BMC is an older chip based on the ARM926 CPU core
that remains in use on Supermicro X9 server boards among others. Support
gets added for a particular server board using this SoC along with the
basic platform bringup.
As the platform is a predecessor to the npcm7xx platform we already
support, it is added to the same directory, despite using a different
name. It also seems to be related to the older w90x900/nuc9xx platform
that was removed last year.

Almost all SoC code changes this time are for the TI OMAP
platform, which continues its decade-long quest to move from
describing a complex SoC in code to device tree.
Aside from this, the Uniphier platform has a new maintainer
and some platforms have minor bugfixes and cleanups that were
not urgent enough for v5.12.

Here is the big set of tty and serial driver updates for 5.13-rc1.
Actually busy this release, with a number of cleanups happening:
- much needed core tty cleanups by Jiri Slaby
- removal of unused and orphaned old-style serial drivers. If
anyone shows up with this hardware, it is trivial to restore
these but we really do not think they are in use anymore.
- fixes and cleanups from Johan Hovold on a number of termios
setting corner cases that loads of drivers got wrong as well
as removing unneeded code due to tty core changes from long
ago that were never propagated out to the drivers
- loads of platform-specific serial port driver updates and
fixes
- coding style cleanups and other small fixes and updates all
over the tty/serial tree.
All of these have been in linux-next for a while now with no reported
issues.

Here is the big set of staging and IIO driver updates for 5.13-rc1.
Lots of little churn in here, and some larger churn as well. Major
things are:
- removal of wimax drivers, no one has this hardware anymore for
this failed "experiment".
- removal of the Google gasket driver, turns out no one wanted
to maintain it or cares about it anymore, so they asked for it
to be removed.
- comedi finally moves out of the staging directory into
drivers/comedi/ This is one of the oldest kernel subsystems
around, being created in the 2.0 kernel days, and was one of
the first things added to drivers/staging/ when that was
created over 15 years ago. It should have been moved out of
staging a long time ago, it's well maintained and used by
loads of different devices in the real world every day. Nice
to see this finally happen.
- so many tiny coding style cleanups it's not funny. Perfect
storm of at least 2 different intern project application
deadlines combined to provide a huge number of new
contributions in this area from people learning how to do
kernel development. Great job to everyone involved here.
There's also the normal updates for IIO drivers with new IIO drivers and
updates all over that subsystem.
All of these have been in linux-next for a while with no reported
issues.

Here is the "big" set of driver core changes for 5.13-rc1.
Nothing major, just lots of little core changes and cleanups, notable
things are:
- finally set fw_devlink=on by default. All reported issues
with this have been shaken out over the past 9 months or so,
but we will be paying attention to any fallout here in case we
need to revert this as the default boot value (symptoms of
problems are a simple lack of booting)
- fixes found to be needed by fw_devlink=on value in some
subsystems (like clock).
- delayed work initialization cleanup
- driver core cleanups and minor updates
- software node cleanups and tweaks
- devtmpfs cleanups
- minor debugfs cleanups
All of these have been in linux-next for a while with no reported
issues.

Using Landlock objects and ruleset, it is possible to tag inodes
according to a process's domain. To enable an unprivileged process to
express a file hierarchy, it first needs to open a directory (or a file)
and pass this file descriptor to the kernel through
landlock_add_rule(2). When checking if a file access request is
allowed, we walk from the requested dentry to the real root, following
the different mount layers. The access to each "tagged" inodes are
collected according to their rule layer level, and ANDed to create
access to the requested file hierarchy. This makes possible to identify
a lot of files without tagging every inodes nor modifying the
filesystem, while still following the view and understanding the user
has from the filesystem.
Add a new ARCH_EPHEMERAL_INODES for UML because it currently does not
keep the same struct inodes for the same inodes whereas these inodes are
in use.
This commit adds a minimal set of supported filesystem access-control
which doesn't enable to restrict all file-related actions. This is the
result of multiple discussions to minimize the code of Landlock to ease
review. Thanks to the Landlock design, extending this access-control
without breaking user space will not be a problem. Moreover, seccomp
filters can be used to restrict the use of syscall families which may
not be currently handled by Landlock.

A Landlock object enables to identify a kernel object (e.g. an inode).
A Landlock rule is a set of access rights allowed on an object. Rules
are grouped in rulesets that may be tied to a set of processes (i.e.
subjects) to enforce a scoped access-control (i.e. a domain).
Because Landlock's goal is to empower any process (especially
unprivileged ones) to sandbox themselves, we cannot rely on a
system-wide object identification such as file extended attributes.
Indeed, we need innocuous, composable and modular access-controls.
The main challenge with these constraints is to identify kernel objects
while this identification is useful (i.e. when a security policy makes
use of this object). But this identification data should be freed once
no policy is using it. This ephemeral tagging should not and may not be
written in the filesystem. We then need to manage the lifetime of a
rule according to the lifetime of its objects. To avoid a global lock,
this implementation make use of RCU and counters to safely reference
objects.
A following commit uses this generic object management for inodes.

This helps validating DTS files.
Changes that require mentioning:
1. reg-names
"mspi_regs" and "bspi_regs" were renamed to "mspi" and "bspi" as that
is what's used in DTS files and in Linux driver
2. interrupt-names
Names were reordered. "mspi_done" has to go first as it's always
required.
3. spi-rx-bus-width
Property description was dropped as it's part of the
spi-controller.yaml
4. Examples:
* drop partitions as they are well documented elsewhere
* regs and interrupts were formatted and reordered to match yaml
* <0x1c> was replaced with <&gic>
* "m25p80" node name became "flash"
* dropped invalid "m25p,fast-read" property
* dropped undocumented and Linux-unused "clock-names"
This rewritten binding validates cleanly using the "dt_binding_check".
Some Linux stored DTS files will require reordering regs and interrupts
to make dtbs_check happy.

Commit 60268b0e82 ("hwmon: (amd_energy) modify the visibility of
the counters") restricted visibility of AMD energy counters to work
around a side-channel attack using energy data to determine which
instructions are executed. The attack is described in 'PLATYPUS:
Software-based Power Side-Channel Attacks on x86'. It relies on quick
and accurate energy readings.
This change made the counters provided by the amd_energy driver
effectively unusable for non-provileged users. However, unprivileged
read access is the whole point of hardware monitoring attributes.
An attempt to remedy the situation by limiting and randomizing access
to chip registers was rejected by AMD. Since the driver is for all
practical purposes unusable, remove it.

These are "all-in-one" CPU liquid coolers that can be monitored and
controlled through a proprietary USB HID protocol.
While the models have differently sized radiators and come with varying
numbers of fans, they are all indistinguishable at the software level.
The driver exposes fan/pump speeds and coolant temperature through the
standard hwmon sysfs interface.
Fan and pump control, while supported by the devices, are not currently
exposed. The firmware accepts up to 61 trip points per channel
(fan/pump), but the same set of trip temperatures has to be maintained
for both; with pwmX_auto_point_Y_temp attributes, users would need to
maintain this invariant themselves.
Instead, fan and pump control, as well as LED control (which the device
also supports for 9 addressable RGB LEDs on the CPU water block) are
left for existing and already mature user-space tools, which can still
be used alongside the driver, thanks to hidraw. A link to one, which I
also maintain, is provided in the documentation.
The implementation is based on USB traffic analysis. It has been
runtime tested on x86_64, both as a built-in driver and as a module.

Another smaller set of fixes for three of the Arm platforms:
TI OMAP:
Fix swapped mmc device order also for omap3 that got changed with the
recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the aliases
should be board specific, all the mmc device instances are all there in
the SoC, and we do probe them by default so that PM runtime can idle the
devices if left enabled from the bootloader.
Qualcomm Snapdragon:
This bypasses the, recently introduced, interconnect handling in the
GENI (serial engine) driver when running off ACPI, as this causes the
GENI probe to fail and the Lenovo Yoga C630 to boot without keyboard
and touchpad.
Allwinner:
One 32kHz clock fix for the beelink gs1, a CD polarity fix for the SoPine,
some MAINTAINERS maintainance, and a clk / reset switch to our headers.

The comedi code came into the kernel back in 2008, but traces its
lifetime to much much earlier. It's been polished and buffed and
there's really nothing preventing it from being part of the "real"
portion of the kernel.
So move it to drivers/comedi/ as it belongs there.
Many thanks to the hundreds of developers who did the work to make this
happen.

Those mainboards contain an ITE chips for management and

They could also be handled by drivers/hwmon/i87.c.
But the SuperIO range used by i87 is already claimed and used by the
firmware.
The following warning is printed at boot:
kernel: ACPI Warning: SystemIO range 0x0000000000000A45-0x0000000000000A46 conflicts with OpRegion 0x0000000000000A45-0x0000000000000A46 (\GSA1.SIO1) (20200528/utaddress-204)
kernel: ACPI: This conflict may cause random problems and system instability
kernel: ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
This driver implements such an ACPI driver.
Unfortunately not all sensor registers are handled by the firmware and even
less are exposed via WMI.

During PCH (platform/board) manufacturing process a global platform
reset has to be induced in order for the configuration changes take
the effect upon following platform reset. This is an internal platform
state and is not intended to be used in the regular platform resets.
The setting is exposed via ETR3 (Extended Test Mode Register 3).
After the manufacturing process is completed the register cannot be
written anymore and is hardware locked.
This setting was commonly done by accessing PMC registers via /dev/mem
but due to security concerns /dev/mem access is much more restricted,
hence the reason for exposing this setting via the dedicated sysfs
interface.
To prevent post manufacturing abuse the register is protected
by hardware locking and the file is set to read-only mode via is_visible
handler.
The register in MMIO space is defined for Cannon Lake and newer PCHs.

This improves the Qualcomm SCM driver logic related to detecting the
calling convention, in particular on SC7180, and fixes a few small
issues in the same.
It introduces additonal sanity checks of the size of loaded segments in
the MDT loader and adds a missing error in the return path of
pdr_register_listener().
It makes it possible to specify the OEM specific firmware path in the
wcn36xx control (and WiFi) driver.
Lastly it adds a missing path specifier in the MAINTAINERS' entry and
fixes a bunch of kerneldoc issues in various drivers.

Merge tag 'qcom-drivers-for-5.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers
More Qualcomm driver updates for 5.13
This improves the Qualcomm SCM driver logic related to detecting the
calling convention, in particular on SC7180, and fixes a few small
issues in the same.
It introduces additonal sanity checks of the size of loaded segments in
the MDT loader and adds a missing error in the return path of
pdr_register_listener().
It makes it possible to specify the OEM specific firmware path in the
wcn36xx control (and WiFi) driver.
Lastly it adds a missing path specifier in the MAINTAINERS' entry and
fixes a bunch of kerneldoc issues in various drivers.

On newer Microsoft Surface models (specifically 7th-generation, i.e.
Surface Pro 7, Surface Book 3, Surface Laptop 3, and Surface Laptop Go),
battery and AC status/information is no longer handled via standard ACPI
devices, but instead directly via the Surface System Aggregator Module
(SSAM), i.e. the embedded controller on those devices.
While on previous generation models, AC status is also handled via SSAM,
an ACPI shim was present to translate the standard ACPI AC interface to
SSAM requests. The SSAM interface itself, which is modeled closely after
the ACPI interface, has not changed.
This commit introduces a new SSAM client device driver to support AC
status/information via the aforementioned interface on said Surface
models.

This is the root interrupt controller used on Apple ARM SoCs such as the
M1. This irqchip driver performs multiple functions:
* Handles both IRQs and FIQs
* Drives the AIC peripheral itself (which handles IRQs)
* Dispatches FIQs to downstream hard-wired clients (currently the ARM
timer).
* Implements a virtual IPI multiplexer to funnel multiple Linux IPIs
into a single hardware IPI

This patchset tries to resolve the diversity in the audio LED
control among the ALSA drivers. A new control layer registration
is introduced which allows to run additional operations on
top of the elementary ALSA sound controls.
A new control access group (three bits in the access flags)
was introduced to carry the LED group information for
the sound controls. The low-level sound drivers can just
mark those controls using this access group. This information
is not exported to the user space, but user space can
manage the LED sound control associations through sysfs
(last patch) per Mark's request. It makes things fully
configurable in the kernel and user space (UCM).
The actual state ('route') evaluation is really easy
(the minimal value check for all channels / controls / cards).
If there's more complicated logic for a given hardware,
the card driver may eventually export a new read-only
sound control for the LED group and do the logic itself.
The new LED trigger control code is completely separated
and possibly optional (there's no symbol dependency).
The full code separation allows eventually to move this
LED trigger control to the user space in future.
Actually it replaces the already present functionality
in the kernel space (HDA drivers) and allows a quick adoption
for the recent hardware (ASoC codecs including SoundWire).
snd_ctl_led 24576 0
The sound driver implementation is really easy:
1) call snd_ctl_led_request() when control LED layer should be
automatically activated
/ it calls module_request("snd-ctl-led") on demand /
2) mark all related kcontrols with
SNDRV_CTL_ELEM_ACCESS_SPK_LED or
SNDRV_CTL_ELEM_ACCESS_MIC_LED

there are also notable code changes for imx and omap regressions as
well as some maintainer file updates.
imx:
- Fix an Ethernet issue on imx6ul-14x14-evk board that is caused by
independent PHY reset.
- Add missing `dma-coherent` property for LayerScape device trees to fix a
kernel BUG report.

I believe TI should be more careful with this, and should assign

Add a UART driver for the new Broadcom 8250 based STB UART. The new
UART is backward compatible with the standard 8250, but has some
additional features. The new features include a high accuracy baud
rate clock system and DMA support.
The driver will use the new optional BAUD MUX clock to select the best
one of the four master clocks (81MHz, 108MHz, 64MHz and 48MHz) to feed
the baud rate selection logic for any requested baud rate. This allows
for more accurate BAUD rates when high speed baud rates are selected.
The driver will use the new UART DMA hardware if the UART DMA registers
are specified in Device Tree "reg" property.
The driver also sets the UPSTAT_AUTOCTS flag when hardware flow control
is enabled. This flag is needed for UARTs that don't assert a CTS
changed interrupt when CTS changes and AFE (Hardware Flow Control) is
enabled.
The driver also contains a workaround for a bug in the Synopsis 8250
core. The problem is that at high baud rates, the RX partial FIFO
timeout interrupt can occur but there is no RX data (DR not set in
the LSR register). In this case the driver will not read the Receive
Buffer Register, which clears the interrupt, and the system will get
continuous UART interrupts until the next RX character arrives. The
fix originally suggested by Synopsis was to read the Receive Buffer
Register and discard the character when the DR bit in the LSR was
not set, to clear the interrupt. The problem was that occasionally
a character would arrive just after the DR bit check and a valid
character would be discarded. The fix that was added will clear
receive interrupts to stop the interrupt, deassert RTS to insure
that no new data can arrive, wait for 1.5 character times for the
sender to react to RTS and then check for data and either do a dummy
read or a valid read. Debugfs error counters were also added and were
used to help create test software that would cause the error condition.
The counters can be found at:
/sys/kernel/debug/bcm7271-uart/<device-name>/stats
This also includes a few fixes for build warnings reported by
the kernel test robot.

Big set in here from Alexandru Ardelean enabling multiple buffer support.
This includes providing a new directory per buffer that combines
what was previously in buffer/ and scan_elements/. Old interfaces still
in place for compatiblity.
Note immuatable branch for scmi patches to allow for some significant
rework going on in that subsystem. Merge required updating to reflect
some changes in IIO.
Late rebase to fix some wrong fixes tags due to some earlier rebases
made necessary by messing up the immutable branch.
IIO New Device Support
* adi,ad5686
- Add info to support AD5673R and AD5677R
* bosch,bmi088
- New driver supporting this accelerometer + gyroscope
* cros_ec_mkbp
- New driver for this proximity sensor that exposes a 'front'
sensor. Very simple switch like device, but driver allows it
to share interface with more sophisticated proximity sensors.
* iio_scmi
- New driver to support ARM SCMI protocol to expose underlying
accelerometers and gyroscopes via this firmware interface.
* st,st_magn
- Add ID for IISMDC magnetometer.
* ti,ads131e0
- New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs
Counter New Device Support
* IRQ or GPIO based counter
- New driver for a conceptually simple counter that uses interrupts
to perform the count.
Features
* core
- Dual buffer supprt including:
Various helpers to centralize handling of bufferer related elements.
Document existing and new IOCTLs
Register the IIO chrdev only if it can actually be used for anything.
Rework attribute group creation in the core (lots of patches)
Merge buffer/ and scan_elements/ entries into one list + maintain
backwards compatible set.
Introduce the internal logic and IOCTL to allow multiple buffers
+ access to an anon FD per buffer to actually read from it.
Tidy up tools/iio/iio_generic_buffer and switch to new interfaces.
Update ABI docs.
A few follow up fixes, unsuprising as this was a huge bit of rework.
- Move common case setting of trig->parent to the core.
- Provide an iio_read_channel_processed_scale() to avoid loss of
precision from iio_read_channel_processed() then applying integer
scale. Use it in ntc_thermistor driver in hwmon.
- Allow drivers to specify labels from elsewhere than DT. Use it for
bmc150 and kxcjk-1013 labels related to position on 2 in one tablets.
- Document label usage for proximity and accelerometer sensors.
- Some local variable renames for consistency
tools
- Add -a parameter to iio_event_monitor to allow autoenabling of events.
* acpi_als
- Add trigger support for devices that don't support notification method.
* adi,ad7124
- Allow more than 8 channels. This is a complex little device, but is
capable of supporting up to 16 channels if the share certain
configuration settings.
* hrtimer-trigger
- Support sampling frequency below 1Hz.
* mediatek,mt8195-auxadc
- Add compatible to binding docs (always also includes mt8173)

- Fix various other minor kernel-doc issues shown by W=1
* core
- Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts.
- Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0
- Add unit tests for iio_format_value()
* docs
- Fix formatting/typos in iio_configfs.rst and buffers.rst
- Add documentation of index in buffers.rst
- Fix scan element description
- Avoid some issues with HTML generation from ABI docs by moving
duplicated defintions to more generic files.

attributes turn up in the wrong place. Too complex to revert the
various patches unfortunately so this is a bit messy.
* fsl,mma3452
- Indentation cleanup.
* hid-sensors
- Size of storage needs to increase for some parts when using quaternions.
- Move the get sensistivity attribute to hid-sensors-common to reduce
duplication. Enable it for more device types.

The jack handling for arizona codecs is being refactored so that it is
done directly by the codec drivers, instead of having an extcon-driver
bind to a separate "arizona-extcon" child-device for this.
drivers/mfd/arizona-core.c has already been updated to no longer
instantiate an "arizona-extcon" child-device for the arizona codecs.
This means that the "arizona-extcon" driver is no longer useful
(there are no longer any devices for it to bind to).
This commit drops the extcon Kconfig / Makefile bits and moves
drivers/extcon/extcon-arizona.c to sound/soc/codecs/arizona-jack.c .
This is a preparation patch for converting the arizona extcon-driver into
a helper library for letting the arizona codec-drivers directly report jack
state through the standard sound/soc/soc-jack.c functions.

Add documentation for the user-space interface of the Surface DTX
(detachment system) driver, used on Microsoft Surface Book series
devices.
Signed-off-by: Maximilian Luz <luzmaximilian@gmail.com>

The Microsoft Surface Book series devices consist of a so-called
clipboard part (containing the CPU, touchscreen, and primary battery)
and a base part (containing keyboard, secondary battery, and optional
discrete GPU). These parts can be separated, i.e. the clipboard can be
detached and used as tablet.
This detachment process is initiated by pressing a button. On the
Surface Book 2 and 3 (targeted with this commit), the Surface Aggregator
Module (i.e. the embedded controller on those devices) attempts to send
a notification to any listening client driver and waits for further
instructions (i.e. whether the detachment process should continue or be
aborted). If it does not receive a response in a certain time-frame, the
detachment process (by default) continues and the clipboard can be
physically separated. In other words, (by default and) without a driver,
the detachment process takes about 10 seconds to complete.
This commit introduces a driver for this detachment system (called DTX).
This driver allows a user-space daemon to control and influence the
detachment behavior. Specifically, it forwards any detachment requests
to user-space, allows user-space to make such requests itself, and
allows handling of those requests. Requests can be handled by either
aborting, continuing/allowing, or delaying (i.e. resetting the timeout
via a heartbeat commend). The user-space API is implemented via the
/dev/surface/dtx miscdevice.
In addition, user-space can change the default behavior on timeout from
allowing detachment to disallowing it, which is useful if the (optional)
discrete GPU is in use.
Furthermore, this driver allows user-space to receive notifications
about the state of the base, specifically when it is physically removed
(as opposed to detachment requested), in what manner it is connected
(i.e. in reverse-/tent-/studio- or laptop-mode), and what type of base
is connected. Based on this information, the driver also provides a
simple tablet-mode switch (aliasing all modes without keyboard access,
i.e. tablet-mode and studio-mode to its reported tablet-mode).
An implementation of such a user-space daemon, allowing configuration of
detachment behavior via scripts (e.g. safely unmounting USB devices
connected to the base before continuing) can be found at [1].

This adds a USB display driver with the intention that it can be
used with future USB interfaced low end displays/adapters. The Linux
gadget device driver will serve as the canonical device implementation.
The following DRM properties are supported:
- Plane rotation
- Connector TV properties
There is also support for backlight brightness exposed as a backlight
device.
Display modes can be made available to the host driver either as DRM
display modes or through EDID. If both are present, EDID is just passed
on to userspace.
Performance is preferred over color depth, so if the device supports
RGB565, DRM_CAP_DUMB_PREFERRED_DEPTH will return 16.
If the device transfer buffer can't fit an uncompressed framebuffer
update, the update is split up into parts that do fit.
Optimal user experience is achieved by providing damage reports either by
setting FB_DAMAGE_CLIPS on pageflips or calling DRM_IOCTL_MODE_DIRTYFB.
LZ4 compression is used if the device supports it.
The driver supports a one bit monochrome transfer format: R1. This is not
implemented in the gadget driver. It is added in preparation for future
monochrome e-ink displays.
The driver is MIT licensed to smooth the path for any BSD port of the
driver.
v2:
- Use devm_drm_dev_alloc() and drmm_mode_config_init()
- drm_fbdev_generic_setup: Use preferred_bpp=0, 16 was a copy paste error
- The drm_backlight_helper is dropped, copy in the code
- Support protocol version backwards compatibility for device
v3:
- Use donated Openmoko USB pid
- Use direct compression from framebuffer when pitch matches, not only on
full frames, so split updates can benefit
- Use __le16 in struct gud_drm_req_get_connector_status
- Set edid property when the device only provides edid
- Clear compression fields in struct gud_drm_req_set_buffer
- Fix protocol version negotiation
- Remove mode->vrefresh, it's calculated
v4:
- Drop the status req polling which was a workaround for something that
turned out to be a dwc2 udc driver problem
- Add a flag for the Linux gadget to require a status request on
SET operations. Other devices will only get status req on STALL errors
- Use protocol specific error codes (Peter)
- Add a flag for devices that want to receive the entire framebuffer on
each flush (Lubomir)
- Retry a failed framebuffer flush
- If mode has changed wait for worker and clear pending damage before
queuing up new damage, fb width/height might have changed
- Increase error counter on bulk transfer failures
- Use DRM_MODE_CONNECTOR_USB
- Handle R1 kmalloc error (Peter)
- Don't try and replicate the USB get descriptor request standard for the
display descriptor (Peter)
- Make max_buffer_size optional (Peter), drop the pow2 requirement since
it's not necessary anymore.
- Don't pre-alloc a control request buffer, it was only 4k
- Let gud.h describe the whole protocol explicitly and don't let DRM
leak into it (Peter)
- Drop display mode .hskew and .vscan from the protocol
- Shorten names: s/GUD_DRM_/GUD_/ s/gud_drm_/gud_/ (Peter)
- Fix gud_pipe_check() connector picking when switching connector
- Drop gud_drm_driver_gem_create_object() cached is default now
- Retrieve USB device from struct drm_device.dev instead of keeping a
pointer
- Honour fb->offsets[0]
- Fix mode fetching when connector status is forced
- Check EDID length reported by the device
- Use drm_do_get_edid() so userspace can overrride EDID
- Set epoch counter to signal connector status change
- gud_drm_driver can be const now
v5:
- GUD_DRM_FORMAT_R1: Use non-human ascii values (Daniel)
- Change name to: GUD USB Display (Thomas, Simon)
- Change one __u32 -> __le32 in protocol header
- Always log fb flush errors, unless the previous one failed
- Run backlight update in a worker to avoid upsetting lockdep (Daniel)
- Drop backlight_ops.get_brightness, there's no readback from the device
so it doesn't really add anything.
- Set dma mask, needed by dma-buf importers
v6:
- Use obj-y in Makefile (Peter)
- Fix missing le32_to_cpu() when using GUD_DISPLAY_MAGIC (Peter)
- Set initial brightness on backlight device
v7:
- LZ4_compress_default() can return zero, check for that
- Fix memory leak in gud_pipe_check() error path (Peter)
- Improve debug and error messages (Peter)
- Don't pass length in protocol structs (Peter)
- Pass USB interface to gud_usb_control_msg() et al. (Peter)
- Improve gud_connector_fill_properties() (Peter)
- Add GUD_PIXEL_FORMAT_RGB111 (Peter)
- Remove GUD_REQ_SET_VERSION (Peter)
- Fix DRM_IOCTL_MODE_OBJ_SETPROPERTY and the rotation property
- Fix dma-buf import (Thomas)
v8:
- Forgot to filter RGB111 from reaching userspace
- Handle a device that only returns unknown device properties (Peter)
- s/GUD_PIXEL_FORMAT_RGB111/GUD_PIXEL_FORMAT_XRGB1111/ (Peter)
- Fix R1 and XRGB1111 format conversion
- Add FIXME about Big Endian being broken (Peter, Ilia)

If this code is actually being used, it can be reverted simply and then

Commit 7b4693e644 ("MAINTAINERS: add uapi directories to API/ABI
section") added include/uapi/ and arch/*/include/uapi/ so that patches
modifying them CC linux-api. However that was already done in the past
and resulted in too much noise and thus later removed, as explained in
b14fd334ff ("MAINTAINERS: trim the file triggers for ABI/API")
To prevent another round of addition and removal in the future, change the
entries to X: (explicit exclusion) for documentation purposes, although
they are not subdirectories of broader included directories, as there is
apparently no defined way to add plain comments in subsystem sections.

Now that the dpaa2-switch driver has basic I/O capabilities on the
switch port net_devices and multiple bridging domains are supported,
move the driver out of staging.
The dpaa2-switch driver is placed right next to the dpaa2-eth driver
since, in the near future, they will be sharing most of the data path.
I didn't implement code reuse in this patch series because I wanted to
keep it as small as possible.
Also, the README is removed from staging with the intention to add
proper rst documentation afterwards to actually match was is supported
by the driver.

While the driver is still marked as maintained in MAINTAINERS, Comtrol
does not really care about this ancient driver. They are still
manufacturing serial devices, but those are controlled only by
out-of-tree drivers.
Comtrol didn't answer my pings, so this driver is apparently
unmaintained. Aside from that, the driver was untouched for years, only
whole-tree changes happened during the past years. The driver needs much
more care, so drop it for now. If someone steps up to reintroduce it,
they need to clean it up first.

I cannot maintain this driver for years due to missing HW. Let's orphan
the entry in MAINTAINERS. And likely drop the driver later as these
devices are likely gone from this world. Mxser provides different
(out-of-tree) drivers for their current devices.

The S3C ADC battery driver is a very old piece of code but still used by
(very old as well) S3C24xx platforms (iPAQ h1930/h1940/rx1950).
Currently the header file is not covered by maintainers file, so it
might look abandoned. Add a new entry for entire S3C ADC battery driver
with Krzysztof Kozlowski as maintainer (as Krzysztof maintains still
Samsung S3C24xx platform) to indicate that some basic review can take
place.
However considering that the S3C24xx platform is quite old with only few
users currently and Krzysztof does not have the actual hardware, let's
mark the driver as "Odd fixes".
