Linus Torvalds 3bad80dab9 Char/Misc and other driver changes for 5.17-rc1
Here is the large set of char, misc, and other "small" driver subsystem
 changes for 5.17-rc1.
 
 Lots of different things are in here for char/misc drivers such as:
 	- habanalabs driver updates
 	- mei driver updates
 	- lkdtm driver updates
 	- vmw_vmci driver updates
 	- android binder driver updates
 	- other small char/misc driver updates
 
 Also smaller driver subsystems have also been updated, including:
 	- fpga subsystem updates
 	- iio subsystem updates
 	- soundwire subsystem updates
 	- extcon subsystem updates
 	- gnss subsystem updates
 	- phy subsystem updates
 	- coresight subsystem updates
 	- firmware subsystem updates
 	- comedi subsystem updates
 	- mhi subsystem updates
 	- speakup subsystem updates
 	- rapidio subsystem updates
 	- spmi subsystem updates
 	- virtual driver updates
 	- counter subsystem updates
 
 Too many individual changes to summarize, the shortlog contains the full
 details.
 
 All of these have been in linux-next for a while with no reported
 issues.

double free or miss freeing the auxiliary devices.

The documentation for creating an auxiliary device is a 3 step not a 2
step process.  Specifically the requirements of setting the name, id,
dev.release, and dev.parent fields was not clear as a precursor to the '2
step' process documented.

Clarify by declaring this a 3 step process starting with setting the
fields of struct auxiliary_device correctly.

Also add some sample code and tie the change into the rest of the
documentation.

Russ Weight 8886a57974 fpga: region: Use standard dev_release for class driver
The FPGA region class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes the
managed resource code and combines the create() and register()
functions into a single register() or register_full() function.

The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.

Jiri Slaby 7e6c0b22f4 tty: move tty_ldisc docs to new Documentation/tty/
Create a new directory in Documentation/ called tty. We will create more
documents in it in the next patches, so let's have this one in the very
same place.

Change title accordingly and all the headers. This is the way what other
documents look like in this directory in the next patches. So make this
unified.

And add a TOC.

Jiri Slaby 4072254f96 tty: reformat tty_struct::flags into kernel-doc
Move the partial tty_struct::flags documentation from tty_ldisc to the
tty.h header and combine it with the one-liners present there. Convert
all those to kernel-doc. This way, we can simply reference the
documentation in Documentation while the text is still along the
definitions.

running the dmatest. This has not been true since commit 6b41030fdc

Daniel Thompson 37829227f0 Documentation: dmaengine: Add a description of what dmatest does
Currently it can difficult to determine what dmatest does without
reading the source code. Let's add a description.

The description is taken mostly from the patch header of
commit 4a776f0aa9 ("dmatest: Simple DMA memcpy test client").
It has been edited and updated slightly. Nevertheless the new text was
largely written by Haarvard Skinnemoen and was copied from another
patch, already committed to the kernel, which has Haarvard's SoB:
attached to it.

Linus Torvalds dd72945c43 cxl for v5.16
- Fix support for platforms that do not enumerate every ACPI0016 (CXL
   Host Bridge) in the CHBS (ACPI Host Bridge Structure).
 
 - Introduce a common pci_find_dvsec_capability() helper, clean up open
   coded implementations in various drivers.
 
 - Add 'cxl_test' for regression testing CXL subsystem ABIs. 'cxl_test'
   is a module built from tools/testing/cxl/ that mocks up a CXL topology
   to augment the nascent support for emulation of CXL devices in QEMU.
 
 - Convert libnvdimm to use the uuid API.
 
 - Complete the definition of CXL namespace labels in libnvdimm.
 
 - Tunnel libnvdimm label operations from nd_ioctl() back to the CXL
   mailbox driver. Enable 'ndctl {read,write}-labels' for CXL.
 
 - Continue to sort and refactor functionality into distinct driver and
   core-infrastructure buckets. For example, mailbox handling is now a
   generic core capability consumed by the PCI and cxl_test drivers.

 "More preparation and plumbing work in the CXL subsystem.

Greg Kroah-Hartman 6bce28cb49 First set of IIO new device and feature support for the 5.16 cycle
Counter subsystem changes now sent separately.
 
 This has been a busy cycle, so lots here and a few more stragglers to
 come next week.
 
 Big new feature in this cycle is probably output buffer support.
 This has been in the works for a very long time so it's great to see
 Mihail pick up the challenge and build upon his predecessors work to finally
 bring this feature to mainline.
 
 New device support
 ------------------
 
 * adi,adxl313
   - New driver and dt bindings for this low power accelerometer.
 * adi,adxl355

First set of IIO new device and feature support for the 5.16 cycle

Counter subsystem changes now sent separately.

This has been a busy cycle, so lots here and a few more stragglers to
come next week.

Big new feature in this cycle is probably output buffer support.
This has been in the works for a very long time so it's great to see
Mihail pick up the challenge and build upon his predecessors work to finally
bring this feature to mainline.

Alexandru Ardelean 25c02edfd4 iio: inkern: introduce devm_iio_map_array_register() short-hand function
This change introduces a device-managed variant to the
iio_map_array_register() function. It's a simple implementation of calling
iio_map_array_register() and registering a callback to
iio_map_array_unregister() with the devm_add_action_or_reset().

The function uses an explicit 'dev' parameter to bind the unwinding to. It
could have been implemented to implicitly use the parent of the IIO device,
however it shouldn't be too expensive to callers to just specify to which
device object to bind this unwind call.
It would make the API a bit more flexible.

Dan Williams 4faf31b434 cxl/mbox: Move mailbox and other non-PCI specific infrastructure to the core
Now that the internals of mailbox operations are abstracted from the PCI
specifics a bulk of infrastructure can move to the core.

The CXL_PMEM driver intends to proxy LIBNVDIMM UAPI and driver requests
to the equivalent functionality provided by the CXL hardware mailbox
interface. In support of that intent move the mailbox implementation to
a shared location for the CXL_PCI driver native IOCTL path and CXL_PMEM
nvdimm command proxy path to share.

A unit test framework seeks to implement a unit test backend transport
for mailbox commands to communicate mocked up payloads. It can reuse all
of the mailbox infrastructure minus the PCI specifics, so that also gets
moved to the core.

Finally with the mailbox infrastructure and ioctl handling being
transport generic there is no longer any need to pass file
file_operations to devm_cxl_add_memdev(). That allows all the ioctl
boilerplate to move into the core for unit test reuse.

No functional change intended, just code movement.

 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

  Detailed summary:

  core:
   - extract i915 eDP backlight into core
   - DP aux bus support
   - drm_device.irq_enabled removed
   - port drivers to native irq interfaces
   - export gem shadow plane handling for vgem

Lightnvm supports the OCSSD 1.x and 2.0 specs which were early attempts
to produce Open Channel SSDs and never made it into the NVMe spec
proper.  They have since been superceeded by NVMe enhancements such
as ZNS support.  Remove the support per the deprecation schedule.

core/pmem.c. Introduce drivers/core/core.h to communicate data
structures and helpers between the core bus and other functionality that
registers devices on the bus.

Ben Widawsky 5161a55c06 cxl: Move cxl_core to new directory
CXL core is growing, and it's already arguably unmanageable. To support
future growth, move core functionality to a new directory and rename the
file to represent just bus support. Future work will remove non-bus
functionality.

Note that mem.h is renamed to cxlmem.h to avoid a namespace collision
with the global ARCH=um mem.h header.

Modernise the documentation to make it more precise and update the use of
pixel rate control and various other changes. In particular:

- Use non-proportional font for file names, properties as well as
  controls.

- The unit of the HBLANK control is pixels, not lines.

- The unit of PIXEL_RATE control is pixels per second, not Hz.

- Merge common requirements for CSI-2 and parallel busses.

- Include all DT properties needed for assigned clocks.

- Fix referencing the link rate control.

- SMIA driver's new name is CCS driver.

- The PIXEL_RATE control denotes pixel rate on the pixel array on camera
  sensors. Do not suggest it is used to tell the maximum pixel rate on the
  bus anymore.

- Improve ReST syntax (plain struct and function names).

- Remove the suggestion to use s_power() in receiver drivers.

- Make MIPI website URL use HTTPS, add Wikipedia links to BT.601 and
  BT.656.

Hannu Hartikainen f3f1017a98 docs: gpio: explain GPIOD_OUT_* values and toggling active low
I was confused about the gpiod_flags values and thought that
GPIOD_OUT_LOW and GPIOD_OUT_HIGH set the line to be active low / active
high. This is not true, but I got the misconception because the flags
GPIOD_OUT_*_OPEN_DRAIN do change line configuration and there's a
subchapter about *active low* and *open drain* semantics.

Add an explicit mention that the initial value is a logical value (and
not the line configuration or physical line level). Also add a mention
of the function gpiod_toggle_active_low which was previously missing
from this document.

This contains mostly various fixes, cleanups and some conversions to the
 atomic API. One noteworthy change is that PWM consumers can now pass a
 hint to the PWM core about the PWM usage, enabling PWM providers to
 implement various optimizations.
 
 There's also a fair bit of simplification here with the addition of some
 device-managed helpers as well as unification between the DT and ACPI
 firmware interfaces.

Pull CXL (Compute Express Link) updates from Dan Williams:
 "This subsystem is still in the build-out phase as the bulk of the
  update is improvements to enumeration and fleshing out the device
  model. In terms of new features, more mailbox commands have been added
  to the allowed-list in support of persistent memory provisioning
  support targeting v5.15.

  The critical update from an enumeration perspective is support for the
  CXL Fixed Memory Window Structure that indicates to Linux which system
  physical address ranges decode to the CXL Host Bridges in the system.
  This allows the driver to detect which address ranges have been mapped
  by firmware and what address ranges are available for future hotplug.

  So, again, mostly skeleton this round, with more meat targeting v5.15.

  Summary:

   - Add support for the CXL Fixed Memory Window Structure, a recent
     extension of the ACPI CEDT (CXL Early Discovery Table)

   - Add infrastructure for component registers

   - Add HDM (Host-managed device memory) decoder definitions

New drivers:
 
 - Last merge window we created a driver for the Ralink RT2880.
   We are now moving the Ralink SoC pin control drivers out of the MIPS
   architecture code and into the pin control subsystem. This concerns
   RT288X, MT7620, RT305X, RT3883 and MT7621.
 
 - Qualcomm SM6125 SoC pin control driver.
 
 - Qualcomm spmi-gpio support for PM7325.
 
 - Qualcomm spmi-mpp also handles PMI8994 (just a compatible string)
 
 - Mediatek MT8365 SoC pin controller.
 
 - New device HID for the AMD GPIO controller.
 
 Improvements:
 
 - Pin bias config support for a slew of Renesas pin controllers.
 
 - Incremental improvements and non-urgent bug fixes to the Renesas
   SoC drivers.
 
 - Implement irq_set_wake on the AMD pin controller so we can wake
   up from external pin events.
 
 Misc:
 
 - Devicetree bindings for the Apple M1 pin controller, we will probably
   see a proper driver for this soon as well.

Jason Gunthorpe 88a21f265c vfio/mdev: Allow the mdev_parent_ops to specify the device driver to bind
This allows a mdev driver to opt out of using vfio_mdev.c, instead the
driver will provide a 'struct mdev_driver' and register directly with the
driver core.

Much of mdev_parent_ops becomes unused in this mode:
- create()/remove() are done via the mdev_driver probe()/remove()
- mdev_attr_groups becomes mdev_driver driver.dev_groups
- Wrapper function callbacks are replaced with the same ones from
  struct vfio_device_ops

Hridya Valsaraju bdb8d06dfe dmabuf: Add the capability to expose DMA-BUF stats in sysfs
Overview
========
The patch adds DMA-BUF statistics to /sys/kernel/dmabuf/buffers. It
allows statistics to be enabled for each DMA-BUF in sysfs by enabling
the config CONFIG_DMABUF_SYSFS_STATS.

The following stats will be exposed by the interface:

/sys/kernel/dmabuf/buffers/<inode_number>/exporter_name
/sys/kernel/dmabuf/buffers/<inode_number>/size
/sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/device
/sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/map_counter

The inode_number is unique for each DMA-BUF and was added earlier [1]
in order to allow userspace to track DMA-BUF usage across different
processes.

Use Cases
=========
The interface provides a way to gather DMA-BUF per-buffer statistics
from production devices. These statistics will be used to derive DMA-BUF
per-exporter stats and per-device usage stats for Android Bug reports.
The corresponding userspace changes can be found at [2].
Telemetry tools will also capture this information(along with other
memory metrics) periodically as well as on important events like a
foreground app kill (which might have been triggered by Low Memory
Killer). It will also contribute to provide a snapshot of the system
memory usage on other events such as OOM kills and Application Not
Responding events.

Background
==========
Currently, there are two existing interfaces that provide information
about DMA-BUFs.
1) /sys/kernel/debug/dma_buf/bufinfo
debugfs is however unsuitable to be mounted in production systems and
cannot be considered as an alternative to the sysfs interface being
proposed.
2) proc/<pid>/fdinfo/<fd>
The proc/<pid>/fdinfo/<fd> files expose information about DMA-BUF fds.
However, the existing procfs interfaces can only provide information
about the buffers for which processes hold fds or have the buffers
mmapped into their address space. Since the procfs interfaces alone
cannot provide a full picture of all DMA-BUFs in the system, there is
the need for an alternate interface to provide this information on
production systems.

The patch contains the following major improvements over v1:
1) Each attachment is represented by its own directory to allow creating
a symlink to the importing device and to also provide room for future
expansion.
2) The number of distinct mappings of each attachment is exposed in a
separate file.
3) The per-buffer statistics are now in /sys/kernel/dmabuf/buffers
inorder to make the interface expandable in future.

All of the improvements above are based on suggestions/feedback from
Daniel Vetter and Christian König.

A shell script that can be run on a classic Linux environment to read
out the DMA-BUF statistics can be found at [3](suggested by John
Stultz).

Dan Williams 4812be97c0 cxl/acpi: Introduce the root of a cxl_port topology
While CXL builds upon the PCI software model for enumeration and
endpoint control, a static platform component is required to bootstrap
the CXL memory layout. Similar to how ACPI identifies root-level PCI
memory resources, ACPI data enumerates the address space and interleave
configuration for CXL Memory.

In addition to identifying host bridges, ACPI is responsible for
enumerating the CXL memory space that can be addressed by downstream
decoders. This is similar to the requirement for ACPI to publish
resources via the _CRS method for PCI host bridges. Specifically, ACPI
publishes a table, CXL Early Discovery Table (CEDT), which includes a
list of CXL Memory resources, CXL Fixed Memory Window Structures
(CFMWS).

For now, introduce the core infrastructure for a cxl_port hierarchy
starting with a root level anchor represented by the ACPI0017 device.

Follow on changes model support for the configurable decode capabilities
of cxl_port instances, i.e. CXL switch support.

Since the macro was introduced in 2019 (commit bb6243b4f7 ("drivers:

Alan Stern 7652dd2c5c USB: core: Check buffer length matches wLength for control transfers
A type of inconsistency that can show up in control URBs is when the
setup packet's wLength value does not match the URB's
transfer_buffer_length field.  The two should always be equal;
differences could lead to information leaks or undefined behavior for
OUT transfers or overruns for IN transfers.

This patch adds a test for such mismatches during URB submission.  If
the test fails, the submission is rejected with a -EBADR error code
(which is not used elsewhere in the USB core), and a debugging message
is logged for people interested in tracking down these errors.

Ben Widawsky 21e9f76733 cxl: Rename mem to pci
As the driver has undergone development, it's become clear that the
majority [entirety?] of the current functionality in mem.c is actually a
layer encapsulating functionality exposed through PCI based
interactions. This layer can be used either in isolation or to provide
functionality for higher level functionality.

CXL capabilities exist in a parallel domain to PCIe. CXL devices are
enumerable and controllable via "legacy" PCIe mechanisms; however, their
CXL capabilities are a superset of PCIe. For example, a CXL device may
be connected to a non-CXL capable PCIe root port, and therefore will not
be able to participate in CXL.mem or CXL.cache operations, but can still
be accessed through PCIe mechanisms for CXL.io operations.

To properly represent the PCI nature of this driver, and in preparation for
introducing a new driver for the CXL.mem / HDM decoder (Host-managed Device
Memory) capabilities of a CXL memory expander, rename mem.c to pci.c so that
mem.c is available for this new driver.

The result of the change is that there is a clear layering distinction
in the driver, and a systems administrator may load only the cxl_pci
module and gain access to such operations as, firmware update, offline
provisioning of devices, and error collection. In addition to freeing up
the file name for another purpose, there are two primary reasons this is
useful,
    1. Acting upon devices which don't have full CXL capabilities. This
       may happen for instance if the CXL device is connected in a CXL
       unaware part of the platform topology.
    2. Userspace-first provisioning for devices without kernel driver
       interference. This may be useful when provisioning a new device
       in a specific manner that might otherwise be blocked or prevented
       by the real CXL mem driver.

Linus Torvalds 65ec0a7d24 This is the bulk of the pin control changes for the v5.13 kernel cycle
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.

Linus Torvalds 0c85556318 ARM: platform support for Apple M1
The Apple M1 is the processor used it all current generation Apple
 Macintosh computers. Support for this platform so far is rudimentary,
 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)
 is work in progress but was not ready in time.
 
 A very detailed description of what works is in the merge commit
 and on the AsahiLinux wiki.

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.

context of
https://lore.kernel.org/linux-pwm/20210406073036.26857-1-u.kleine-koenig@pengutronix.de/
but was then missed to adapt when this patch was reduced to a
documentation update.)

While at is also clarify "last applied PWM state" to "PWM state that was
passed to the last invocation of pwm_apply_state()" to better
distinguish to the last actually implemented state and reword to drop a

Hector Martin 7c566bb5e4 asm-generic/io.h: Add a non-posted variant of ioremap()
ARM64 currently defaults to posted MMIO (nGnRE), but some devices
require the use of non-posted MMIO (nGnRnE). Introduce a new ioremap()
variant to handle this case. ioremap_np() returns NULL on arches that
do not implement this variant.

sparc64 is the only architecture that needs to be touched directly,
because it includes neither of the generic io.h or iomap.h headers.

This adds the IORESOURCE_MEM_NONPOSTED flag, which maps to this
variant and marks a given resource as requiring non-posted mappings.
This is implemented in the resource system because it is a SoC-level
requirement, so existing drivers do not need special-case code to pick
this ioremap variant.

Then this is implemented in devres by introducing devm_ioremap_np(),
and making devm_ioremap_resource() automatically select this variant
when the resource has the IORESOURCE_MEM_NONPOSTED flag set.

Jason Gunthorpe 91b9969d9c vfio/mdev: Simplify driver registration
This is only done once, we don't need to generate code to initialize a
structure stored in the ELF .data segment. Fill in the three required
.driver members directly instead of copying data into them during
mdev_register_driver().

Further the to_mdev_driver() function doesn't belong in a public header,
just inline it into the two places that need it. Finally, we can now
clearly see that 'drv' derived from dev->driver cannot be NULL, firstly
because the driver core forbids it, and secondly because NULL won't pass
through the container_of(). Remove the dead code.

Jason Gunthorpe 2a3d15f270 vfio/mdev: Add missing typesafety around mdev_device
The mdev API should accept and pass a 'struct mdev_device *' in all
places, not pass a 'struct device *' and cast it internally with
to_mdev_device(). Particularly in its struct mdev_driver functions, the
whole point of a bus's struct device_driver wrapper is to provide type
safety compared to the default struct device_driver.

Further, the driver core standard is for bus drivers to expose their
device structure in their public headers that can be used with
container_of() inlines and '&foo->dev' to go between the class levels, and
'&foo->dev' to be used with dev_err/etc driver core helper functions. Move
'struct mdev_device' to mdev.h

Once done this allows moving some one instruction exported functions to
static inlines, which in turns allows removing one of the two grotesque
symbol_get()'s related to mdev in the core code.

This is the standard kernel pattern, the ops associated with a struct get
the struct pointer in for typesafety. The expected design is to use
container_of to cleanly go from the subsystem level type to the driver
level type without having any type erasure in a void *.

Jason Gunthorpe 0bfc6a4ea6 vfio: Split creation of a vfio_device into init and register ops
This makes the struct vfio_device part of the public interface so it
can be used with container_of and so forth, as is typical for a Linux
subystem.

This is the first step to bring some type-safety to the vfio interface by
allowing the replacement of 'void *' and 'struct device *' inputs with a
simple and clear 'struct vfio_device *'

For now the self-allocating vfio_add_group_dev() interface is kept so each
user can be updated as a separate patch.

The expected usage pattern is

  driver core probe() function:
     my_device = kzalloc(sizeof(*mydevice));
     vfio_init_group_dev(&my_device->vdev, dev, ops, mydevice);
     /* other driver specific prep */
     vfio_register_group_dev(&my_device->vdev);
     dev_set_drvdata(dev, my_device);

  driver core remove() function:
     my_device = dev_get_drvdata(dev);
     vfio_unregister_group_dev(&my_device->vdev);
     /* other driver specific tear down */
     kfree(my_device);

Allowing the driver to be able to use the drvdata and vfio_device to go
to/from its own data.

The pattern also makes it clear that vfio_register_group_dev() must be
last in the sequence, as once it is called the core code can immediately
start calling ops. The init/register gap is provided to allow for the
driver to do setup before ops can be called and thus avoid races.

While the discussion is still fresh I figured good time to try and

what's the potential problem, and the remedies we've discussed,
roughly ordered from best to worst.

v2: Linus -> Linux typoe (Dave)

v3:
- Make it clear drivers only need to implement one option (Christian)
- Make it clearer that implicit sync is out the window with exclusive
  fences (Christian)
- Add the fairly theoretical option of segementing the memory (either
  statically or through dynamic checks at runtime for which piece of
  memory is managed how) and explain why it's not a great idea (Felix)

This change does a conversion of the devm_iio_dmaengine_buffer_alloc() to
devm_iio_dmaengine_buffer_setup(). This will allocate an IIO DMA buffer and

(though the underlying code is different, the final logic is the same).

Since the only user of the devm_iio_dmaengine_buffer_alloc() was the

With this change, the devm_iio_kfifo_allocate() will be made private to the

This change adds the devm_iio_kfifo_buffer_setup() helper/short-hand,
which groups the simple routine of allocating a kfifo buffers via
devm_iio_kfifo_allocate() and calling iio_device_attach_buffer().

The mode_flags parameter is required, as the IIO kfifo supports 2 modes:
INDIO_BUFFER_SOFTWARE & INDIO_BUFFER_TRIGGERED.
The setup_ops parameter is optional.

This function will be a bit more useful when needing to define multiple
buffers per IIO device.

The naming for this function has been inspired from
iio_triggered_buffer_setup() since that one does a kfifo alloc + a pollfunc
alloc. So, this should have a more familiar ring to what it is.

Maximilian Luz 03ee318391 platform/surface: aggregator: Make SSAM_DEFINE_SYNC_REQUEST_x define static functions
The SSAM_DEFINE_SYNC_REQUEST_x() macros are intended to reduce
boiler-plate code for SSAM request definitions by defining a wrapper
function for the specified request. The client device variants of those
macros, i.e. SSAM_DEFINE_SYNC_REQUEST_CL_x() in particular rely on the
multi-device (MD) variants, e.g.:

    #define SSAM_DEFINE_SYNC_REQUEST_CL_R(name, rtype, spec...)   \
        SSAM_DEFINE_SYNC_REQUEST_MD_R(__raw_##name, rtype, spec)  \
        int name(struct ssam_device *sdev, rtype *ret)            \
        {                                                         \
            return __raw_##name(sdev->ctrl, sdev->uid.target,     \
                                sdev->uid.instance, ret);         \
        }

This now creates the problem that it is not possible to declare the
generated functions static via

    static SSAM_DEFINE_SYNC_REQUEST_CL_R(...)

as this will only apply to the function defined by the multi-device
macro, i.e. SSAM_DEFINE_SYNC_REQUEST_MD_R(). Thus compiling with
`-Wmissing-prototypes' rightfully complains that there is a 'static'
keyword missing.

To solve this, make all SSAM_DEFINE_SYNC_REQUEST_x() macros define
static functions. Non-client-device macros are also changed for
consistency. In general, we expect those functions to be only used
locally in the respective drivers for the corresponding interfaces, so
having to define a wrapper function to be able to export this should be
the odd case out.

Linus Torvalds e229b429bb Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for
 5.12-rc1.  Over time it seems like this tree is collecting more and more
 tiny driver subsystems in one place, making it easier for those
 maintainers, which is why this is getting larger.
 
 Included in here are:
 	- coresight driver updates
 	- habannalabs driver updates
 	- virtual acrn driver addition (proper acks from the x86
 	  maintainers)
 	- broadcom misc driver addition
 	- speakup driver updates
 	- soundwire driver updates
 	- fpga driver updates
 	- amba driver updates
 	- mei driver updates
 	- vfio driver updates
 	- greybus driver updates
 	- nvmeem driver updates
 	- phy driver updates
 	- mhi driver updates
 	- interconnect driver udpates
 	- fsl-mc bus driver updates
 	- random driver fix
 	- some small misc driver updates (rtsx, pvpanic, etc.)
 
 All of these have been in linux-next for a while, with the only reported
 issue being a merge conflict in include/linux/mod_devicetable.h that you
 will hit in your tree due to the dfl_device_id addition from the fpga
 subsystem in here.  The resolution should be simple.

Linus Torvalds 825d150875 cxl for 5.12
Introduce an initial driver for CXL 2.0 Type-3 Memory Devices. CXL is
 Compute Express Link which released the 2.0 specification in November.
 The Linux relevant changes in CXL 2.0 are support for an OS to
 dynamically assign address space to memory devices, support for
 switches, persistent memory, and hotplug. A Type-3 Memory Device is a
 PCI enumerated device presenting the CXL Memory Device Class Code and
 implementing the CXL.mem protocol. CXL.mem allows device to advertise
 CPU and I/O coherent memory to the system, i.e. typical "System RAM" and
 "Persistent Memory" in Linux /proc/iomem terms.
 
 In addition to the CXL.mem fast path there is an administrative command
 hardware mailbox interface for maintenance and provisioning. It is this
 command interface that is the focus of the initial driver. With this
 driver a CXL device that is mapped by the BIOS can be administered by
 Linux. Linux support for CXL PMEM and dynamic CXL address space
 management are to be implemented post v5.12.

Linus Torvalds 0e63a5c6ba It has been a relatively quiet cycle in docsland.
- As promised, the minimum Sphinx version to build the docs is now 1.7,
    and we have dropped support for Python 2 entirely.  That allowed the
    removal of a bunch of compatibility code.
 
  - A set of treewide warning fixups from Mauro that I applied after it
    became clear nobody else was going to deal with them.
 
  - The automarkup mechanism can now create cross-references from relative
    paths to RST files.
 
  - More translations, typo fixes, and warning fixes.
 
 No conflicts with any other tree as far as I know.
