Biju Das 654c293e16 mfd: Add Renesas RZ/G2L MTU3a core driver
The RZ/G2L multi-function timer pulse unit 3 (MTU3a) is embedded in
the Renesas RZ/G2L family SoCs. It consists of eight 16-bit timer
channels and one 32-bit timer channel. It supports the following
functions
 - Counter
 - Timer
 - PWM

The 8/16/32 bit registers are mixed in each channel.

Add MTU3a core driver for RZ/G2L SoC. The core driver shares the
clk and channel register access for the other child devices like
Counter, PWM and Clock event.

Uwe Kleine-König a29f5a3eeb mfd: rsmu_i2c: Convert to i2c's .probe_new() again
This commit reapplies commit 601e6d48ee ("mfd: rsmu_i2c: Convert to
i2c's .probe_new()") which was accidently reverted by commit
1b3b1d6c27cc ("mfd: rsmu: Support 32-bit address space").

Without this change the driver fails to build in combination with commit
03c835f498 ("i2c: Switch .probe() to not take an id parameter") which
is contained in v6.3-rc2.

Colin Foster f0484d2f80 mfd: ocelot-spi: Fix unsupported bulk read
Ocelot chips (VSC7511, VSC7512, VSC7513, VSC7514) don't support bulk read
operations over SPI.

Many SPI buses have hardware that can optimize consecutive reads.
Essentially an address is written to the chip, and if the SPI controller
continues to toggle the clock, subsequent register values are reported.
This can lead to significant optimizations, because the time between
"address is written to the chip" and "chip starts to report data" can often
take a fixed amount of time.

When support for Ocelot chips were added in commit f3e893626a ("mfd:
ocelot: Add support for the vsc7512 chip via spi") it was believed that
this optimization was supported. However it is not.

Most register transactions with the Ocelot chips are not done in bulk, so
this bug could go unnoticed. The one scenario where bulk register
operations _are_ performed is when polling port statistics counters, which
was added in commit d87b1c08f3 ("net: mscc: ocelot: use bulk reads for
stats").

Things get slightly more complicated here...

A bug was introduced in commit d4c3676507 ("net: mscc: ocelot: keep
ocelot_stat_layout by reg address, not offset") that broke the optimization
of bulk reads. This means that when Ethernet support for the VSC7512 chip
was added in commit 3d7316ac81 ("net: dsa: ocelot: add external ocelot
switch control") things were actually working "as expected".

The bulk read opmtimization was discovered, and fixed in commit
6acc72a43e ("net: mscc: ocelot: fix stats region batching") and the
timing optimizations for SPI were noticed. A bulk read went from ~14ms to
~2ms. But this timing improvement came at the cost of every register
reading zero due the fact that bulk reads don't work.

The read timings increase back to 13-14ms, but that's a price worth paying
in order to receive valid data. This is verified in a DSA setup (cpsw-new
switch tied to port 0 on the VSC7512, after having been running overnight)

Patrick Rudolph 0742c2a633 mfd: max597x: Add support for MAX5970 and MAX5978
Implement a regulator driver with IRQ support for fault management.
Written against documentation [1] and [2] and tested on real hardware.

Every channel has it's own regulator supply nammed 'vss1-supply' and
'vss2-supply'. The regulator supply is used to determine the output
voltage, as the smart switch provides no output regulation.
The driver requires the 'shunt-resistor-micro-ohms' to be present in
the devicetree to properly calculate current related values.

You must specify compatible devictree layout:

regulator@3a {
        reg = <0x3a>;
        vss1-supply = <&p3v3>;
        compatible = "maxim,max5978";

        ...

        regulators {
                sw0_ref: SW0 {
                        regulator-compatible = "SW0";
                        shunt-resistor-micro-ohms = <12000>;
                        ...
                }
        }
}

1: https://datasheets.maximintegrated.com/en/ds/MAX5970.pdf
2: https://datasheets.maximintegrated.com/en/ds/MAX5978.pdf

...
Changes in V12:
- Use simple_mfd_i2c driver and remove previous implementation.
- Remove newline
- Use _MFD_MAX597X_H in header file
- Successfull build need following patch from regulator:

It seems that this driver was developed based on preliminary documentation.
Report the correct names for all TQMxE39x variants, as they are used by
the released hardware revisions:

- Fix names for TQMxE39C1/C2 board IDs
- Distinguish TQMxE39M and TQMxE39S, which use the same board ID

The TQMxE39M/S are distinguished using the SAUC (Sanctioned Alternate
Uses Configuration) register of the GPIO controller. This also prepares
for the correct handling of the differences between the GPIO controllers
of our COMe and SMARC modules.

there aren't actually any bounds checks for IO port accesses.

Extending the range does not seem like a good solution here, as it would
then conflict with the IO resource assigned to the I2C controller. As
this is just a one-off access during probe, use a simple inb() instead.

While we're at it, drop the unused define TQMX86_REG_I2C_INT_EN.

Aidan MacDonald 172a293707 mfd: qcom-pm8008: Fix swapped mask/unmask in irq chip
The usual behavior of mask registers is writing a '1' bit to
disable (mask) an interrupt; similarly, writing a '1' bit to
an unmask register enables (unmasks) an interrupt.

Due to a longstanding issue in regmap-irq, mask and unmask
registers were inverted when both kinds of registers were
present on the same chip, ie. regmap-irq actually wrote '1's
to the mask register to enable an IRQ and '1's to the unmask
register to disable an IRQ.

This was fixed by commit e8ffb12e7f ("regmap-irq: Fix
inverted handling of unmask registers") but the fix is opt-in
via mask_unmask_non_inverted = true because it requires manual
changes for each affected driver. The new behavior will become
the default once all drivers have been updated.

The PM8008 appears to rely on the inverted behavior. It has
separate set & clear registers for a register called INT_EN,
which presumably enables interrupts by writing '1's. Opt in
to the new non-inverted behavior & swap mask_base/unmask_base.

regmap: allow upshifting register addresses before performing operations
Similar to the existing reg_downshift mechanism, that is used to
translate register addresses on busses that have a smaller address
stride, it's also possible to want to upshift register addresses.

Such a case was encountered when network PHYs and PCS that usually sit
on a MDIO bus (16-bits register with a stride of 1) are integrated
directly as memory-mapped devices. Here, the same register layout
defined in 802.3 is used, but the register now have a larger stride.

Introduce a mechanism to also allow upshifting register addresses.
Re-purpose reg_downshift into a more generic, signed reg_shift, whose
sign indicates the direction of the shift. To avoid confusion, also
introduce macros to explicitly indicate if we want to downshift or
upshift.

For bisectability, change any use of reg_downshift to use reg_shift.

Jeremy Kerr 7d1e3bd948 mfd: syscon: Allow reset control for syscon devices
Simple syscon devices may require deassertion of a reset signal in order
to access their register set. Rather than requiring a custom driver to
implement this, we can use the generic "resets" specifiers to link a
reset line to the syscon.

This change adds an optional reset line to the syscon device
description, and deasserts the reset if detected.

Samuel Holland 1b1305e95e mfd: axp20x: Switch to the sys-off handler API
This removes a layer of indirection through pm_power_off() and allows
the PMIC handler to be used as a fallback when firmware power off fails.
This happens on boards like the Clockwork DevTerm R-01 where OpenSBI
does not know how to use the PMIC to power off the board.

Move the check for AXP288 to avoid registering a dummy handler.

TWL6032 has a few charging registers prepended before the charging
registers the TWL6030 has. To be able to use common register defines
declare the additional registers as additional module.
At the moment this affects the access to CHARGERUSB_CTRL1 in
phy-twl6030-usb.  Without this patch, it is accessing the wrong register
on TWL6032.
The consequence is that presence of Vbus is not reported.

Tom Fitzhenry 5d69b181cd mfd: rk808: Re-add rk808-clkout to RK818
Fixes RK818 (e.g. on Pinephone Pro) to register its clock, without which
dependent devices (e.g. wifi/BT, via sdio-wifi-pwrseq) fail to probe.

This line was removed in commit 3633daacea
("mfd: rk808: Permit having multiple PMIC instances"), but only from RK818.

Linus Torvalds 5b7c4cabbb Networking changes for 6.3.
Core
 ----
 
  - Add dedicated kmem_cache for typical/small skb->head, avoid having
    to access struct page at kfree time, and improve memory use.
 
  - Introduce sysctl to set default RPS configuration for new netdevs.
 
  - Define Netlink protocol specification format which can be used
    to describe messages used by each family and auto-generate parsers.
    Add tools for generating kernel data structures and uAPI headers.
 
  - Expose all net/core sysctls inside netns.
 
  - Remove 4s sleep in netpoll if carrier is instantly detected on boot.
 
  - Add configurable limit of MDB entries per port, and port-vlan.
 
  - Continue populating drop reasons throughout the stack.
 
  - Retire a handful of legacy Qdiscs and classifiers.
 
 Protocols
 ---------
 
  - Support IPv4 big TCP (TSO frames larger than 64kB).
 
  - Add IP_LOCAL_PORT_RANGE socket option, to control local port range
    on socket by socket basis.
 
  - Track and report in procfs number of MPTCP sockets used.
 
  - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
    path manager.
 
  - IPv6: don't check net.ipv6.route.max_size and rely on garbage
    collection to free memory (similarly to IPv4).
 
  - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
 
  - ICMP: add per-rate limit counters.
 
  - Add support for user scanning requests in ieee802154.
 
  - Remove static WEP support.
 
  - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
    reporting.
 
  - WiFi 7 EHT channel puncturing support (client & AP).
 
 BPF
 ---
 
  - Add a rbtree data structure following the "next-gen data structure"
    precedent set by recently added linked list, that is, by using
    kfunc + kptr instead of adding a new BPF map type.
 
  - Expose XDP hints via kfuncs with initial support for RX hash and
    timestamp metadata.
 
  - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
    to better support decap on GRE tunnel devices not operating
    in collect metadata.
 
  - Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
 
  - Remove the need for trace_printk_lock for bpf_trace_printk
    and bpf_trace_vprintk helpers.
 
  - Extend libbpf's bpf_tracing.h support for tracing arguments of
    kprobes/uprobes and syscall as a special case.
 
  - Significantly reduce the search time for module symbols
    by livepatch and BPF.
 
  - Enable cpumasks to be used as kptrs, which is useful for tracing
    programs tracking which tasks end up running on which CPUs in
    different time intervals.
 
  - Add support for BPF trampoline on s390x and riscv64.
 
  - Add capability to export the XDP features supported by the NIC.
 
  - Add __bpf_kfunc tag for marking kernel functions as kfuncs.
 
  - Add cgroup.memory=nobpf kernel parameter option to disable BPF
    memory accounting for container environments.
 
 Netfilter
 ---------
 
  - Remove the CLUSTERIP target. It has been marked as obsolete
    for years, and we still have WARN splats wrt. races of
    the out-of-band /proc interface installed by this target.
 
  - Add 'destroy' commands to nf_tables. They are identical to
    the existing 'delete' commands, but do not return an error if
    the referenced object (set, chain, rule...) did not exist.
 
 Driver API
 ----------
 
  - Improve cpumask_local_spread() locality to help NICs set the right
    IRQ affinity on AMD platforms.
 
  - Separate C22 and C45 MDIO bus transactions more clearly.
 
  - Introduce new DCB table to control DSCP rewrite on egress.
 
  - Support configuration of Physical Layer Collision Avoidance (PLCA)
    Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
    shared medium Ethernet.
 
  - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
    preemption of low priority frames by high priority frames.
 
  - Add support for controlling MACSec offload using netlink SET.
 
  - Rework devlink instance refcounts to allow registration and
    de-registration under the instance lock. Split the code into multiple
    files, drop some of the unnecessarily granular locks and factor out
    common parts of netlink operation handling.
 
  - Add TX frame aggregation parameters (for USB drivers).
 
  - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
    messages with notifications for debug.
 
  - Allow offloading of UDP NEW connections via act_ct.
 
  - Add support for per action HW stats in TC.
 
  - Support hardware miss to TC action (continue processing in SW from
    a specific point in the action chain).
 
  - Warn if old Wireless Extension user space interface is used with
    modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
    for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
    interface instead.
 
  - Improve the CAN bit timing configuration. Use extack to return error
    messages directly to user space, update the SJW handling, including
    the definition of a new default value that will benefit CAN-FD
    controllers, by increasing their oscillator tolerance.

Ilpo Järvinen acf63c458b fpga: m10bmc-sec: Add support for N6000
Add support for PMCI-based flash access path and N6000 sec update
support. Access to flash staging area is different for N6000 from that
of the SPI interfaced counterparts.

Introduce intel_m10bmc_flash_bulk_ops to allow interface specific
differentiations for the flash access path for sec update and make
m10bmc_sec_read/write() in sec update driver to use the new operations.
The .flash_mutex serializes read/read. Flash update (erase+write) must
use ->lock/unlock_write() to prevent reads during update (reads would
timeout on setting flash MUX as BMC will prevent it).

Create a type specific RSU status reg handler for N6000 because the
field has moved from doorbell to auth result register.

If a failure is detected while altering the flash MUX, it seems safer
to try to set it back and doesn't seem harmful. Likely there are enough
troubles in that case anyway so setting it back fails too (which is
harmless sans the small extra delay) or just confirms that the value
wasn't changed.

Ilpo Järvinen 869b9eddf0 mfd: intel-m10-bmc: Add PMCI driver
Add the mfd driver for the Platform Management Component Interface
(PMCI) based interface of Intel MAX10 BMC controller.

PMCI is a software-visible interface, connected to card BMC which
provided the basic functionality of read/write BMC register. The access
to the register is done indirectly via a hardware controller/bridge
that handles read/write/clear commands and acknowledgments for the
commands.

Previously, intel-m10-bmc provided sysfs under
/sys/bus/spi/devices/... which is generalized in this change because
not all MAX10 BMC appear under SPI anymore.

BMC type specific info is currently set by a switch/case block. The
size of this info is expected to grow as more dev types and features

Store type specific info into struct and place them into .driver_data
instead because it makes things a bit cleaner.

The m10bmc_type enum can be dropped as the differentiation is now
fully handled by the platform info.

The info member of struct intel_m10bmc that is added here is not used
yet in this change but its addition logically still belongs to this
change. The CSR map change that comes after this change needs to have
the info member.

SCP Core-1 as a new CrOS EC MCU") was not first added in the source EC
code base[1]. This can lead to the possible misinterpration of an EC's
supported feature set, as well as causes issues with all future feature
flag updates.

Yang Yingliang 14f8c55d48 mfd: pm8008: Fix return value check in pm8008_probe()
In case of error, the function devm_regmap_init_i2c() returns
ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().
