soc: fixes for 6.12, part 2
Where the last set of fixes was mostly drivers, this time the devicetree changes all come at once, targeting mostly the Rockchips, Qualcomm and NXP platforms. The Qualcomm bugfixes target the Snapdragon X Elite laptops, specifically problems with PCIe and NVMe support to improve reliability, and a boot regresion on msm8939. Also for Snapdragon platforms, there are a number of correctness changes in the several platform specific device drivers, but none of these are as impactful. On the NXP i.MX platform, the fixes are all for 64-bit i.MX8 variants, correcting individual entries in the devicetree that were incorrect and causing the media, video, mmc and spi drivers to misbehave in minor ways. The Arm SCMI firmware driver gets fixes for a use-after-free bug and for correctly parsing firmware information. On the RISC-V side, there are three minor devicetree fixes for starfive and sophgo, again addressing only minor mistakes. One device driver patch fixes a problem with spurious interrupt handling. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmcpR7oACgkQYKtH/8kJ Uic9dA/+NzeNald+ap++pYYmIx9FcV3q3aieN4j5NRgAwUS84bNXpARkDQAK8lx8 GFzH7VUe0YwKlh+70P73eaLqsRyYE37eUyvabwnxgO0QnI798MZfM5diDvAFm0LK kQKnNLx0qojt6HQTN3PVfOn+rcp2J5dgUV+ZAG9TEM3YKA0MY/bABRqaZtIZzSxg WwM+jqFh5+EugiioSlL6HCdAVk12wwEJkAInEEY1y/KaeQS9K8vzEOwk4FDeIf2a 3V+G7IVIBI4rbvrAs2ukW3OrRiGT+svINS5k7qkap13YZUUjENnJYGYNm6woTTyb INpBowLKr1gJ1Aluk8AELvpa+aX1BY9rkxP+vTG0HrZVdrPcPToFUBQA4qZgpu/i k0uWb20uN1b2Uor2XP2hcTxvzfKPlvnYHxLTMG89PxoVrMX+oEQoCrAP24YcSkPd srV0aU54MUHANXEnNco0txdElK+8L7ZCyB19KpVnqqshohDpQ+zkX15Hw9uQLwEc RbF99SrR9KFg3sY62Q7LgJOhQ3x6LjGhqPCjejIZ9DvEzndArKYnkkiJYdxxhqkB WN1LB/PmnKPAAh1lJdej6SPhiwCCpEFG3IyS/H1/lv7CR94LVode1J4dYTJmcZaq aownmb4W1zECgMGQS6YjhuAG1h7D0QtSmWBAuiC+H+T2QTRPtKI= =9YYG -----END PGP SIGNATURE----- Merge tag 'arm-fixes-6.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC fixes from Arnd Bergmann: "Where the last set of fixes was mostly drivers, this time the devicetree changes all come at once, targeting mostly the Rockchips, Qualcomm and NXP platforms.

Qualcomm driver fixes for v6.12
The Qualcomm EDAC driver's configuration of interrupts is made optional, to avoid violating security constriants on X Elite platform . The SCM drivers' detection mechanism for the presence of SHM bridge in QTEE, is corrected to handle the case where firmware successfully returns that the interface isn't supported. The GLINK driver and the PMIC GLINK interface is updated to handle buffer allocation issues during initialization of the communication channel. Allocation error handling in the socinfo dirver is corrected, and then the fix is corrected. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmck/kgVHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FqV8QAMEYiZp4KnS6QkT4h47ET/dl3AiY EIyUge41uXjJYO4rK2JpYWi2Y30CXXwb0MRuhfZyI47mU2xYqP30hLEliqZLQqU3 ulc4hmVyPeelRtpSX36UyZQWcaTcr0IyWnhnPSPoIr/WuyvFojBVucnAzHGFYHw6 0Wl0Uwg0vaoptAXnAxC671ggkbXeUuxR1sOMnVAzAL9sUgZMAjDHg+Yc/Oz0i7KZ 16OcOPFWhN+PegrIAPKx5J3X9PUsEoPqE83y3DdRVv62c58RU5tfhrhEIhmo3DVn ruTbrf1vV6cE1iWfGQIxyVt0WJGnY/dZqQjQxinZF0U9dlJl5+ke9ZTsaRxF0s0J wejMDOoqtRbNeotLxhQAp0KbPbcUHg8kkUrYMiTZLMh4eNIEBi4yLT8KhDT7IUgT SEP6jK4z482xpaTrDf5hDmnIMSfAO9fC50QiUMc8eNGL84XYIJgcYfi+LAP7TSiV wP6PI1moQcSvq034csy4AfHlsULxMdqzqh86N4DSdkoa/om2JRiYIXfTkZOteOEg GR4gPYigdBV8X4jj4XDiRbk+hbf+bbc6qet0HKvBPjYcKyvpH+SEVMsuxzAO8ybP RjP5pDrOSb7mLlx/q8RBUwyuVWk6gtDhL6tgvwfP+qu+dxTcHgRSqAi5BQfOWMvf 2K4QO3/0tYunyqaf =H31v -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmcoyr0ACgkQYKtH/8kJ UiebJA/+OwoABEZcspBT92CnlAaIgIITx0znuO9srUcaiNxOTrZH2+T6z+sKHvOV bfhj0JZyK0Qk6sxU9PoczIXb2Xc42lemkZwL6TfDjQlOI10mvfTOgnIFPldG1RIp FcFjI3Tb6SKqh9GxDm5qLdxFn8ZoGKTLtUpP3FuV6lQNpiS7jLJILSNFXbVVMnk/ U2HY76YQ8u2DPk5ZXmjrw49NRDvQ22ufwxJJctE0fvVyr+AUhTFBHH9h6fo3RxbC 4IMCmEfVLnJ+ye9CqB4ahkcbu4gwzzU0eRpMb7mZ2GhufuCjgfBYA4U2XZhdEv0w 9GenVlPr0Hs1dtpUBxvfNf0kJ2uyti4UGkW7gn8+m/sl73bMVIGPX72rxdk3vbir yztmdl3Nya0Nh9fPJxwP4BT6JsMshsz0POzvIOqeRTUw9yKD+wIQg9a+cwWWqdlu jNvBGprW7MS03uQWIWYTGkjqDsStZVJaFO//PHx+ZZ0eY/H2Lminf3GL2tsAYUtE pIVsS4NUcCygEELb7cEbi+S9EMkgQZPd71VAex9bjKNquBs60fSU1GZr3oOuHluv 2XI2O+FPwdTH+yAXzqRlCj5Rczum0joa9q2lHW7hs/h7AKVSNCfzj+0YjDFIhu2E BnS0nbwm5axYm7vsnfA4O4QkE6AtGlRpmVfiumLg/Vif8KsA3N8= =2qZ7 -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-fixes-for-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/fixes Qualcomm driver fixes for v6.12 The Qualcomm EDAC driver's configuration of interrupts is made optional, to avoid violating security constriants on X Elite platform .

arm64 fixes for -rc6
- Fix handling of POR_EL0 during signal delivery so that pushing the
signal context doesn't fail based on the pkey configuration of the
interrupted context and align our user-visible behaviour with that of
x86.
- Fix a bogus pointer being passed to the CPU hotplug code from the
Arm SDEI driver.
- Re-enable software tag-based KASAN with GCC by using an alternative
implementation of '__no_sanitize_address'.

Pull arm64 fixes from Will Deacon:
"The important one is a change to the way in which we handle protection
keys around signal delivery so that we're more closely aligned with
the x86 behaviour, however there is also a revert of the previous fix
to disable software tag-based KASAN with GCC, since a workaround
materialised shortly afterwards.
I'd love to say we're done with 6.12, but we're aware of some
longstanding fpsimd register corruption issues that we're almost at
the bottom of resolving.
Summary:
- Fix handling of POR_EL0 during signal delivery so that pushing the
signal context doesn't fail based on the pkey configuration of the
interrupted context and align our user-visible behaviour with that
of x86.
- Fix a bogus pointer being passed to the CPU hotplug code from the
Arm SDEI driver.

implementation of '__no_sanitize_address'"

Arm SCMI fixes for v6.12(part 2)
Couple of fixes to address slab-use-after-free in scmi_bus_notifier() via scmi_dev->name and possible incorrect clear channel transport operation on A2P channel if some sort of P2A only messages are initiated on A2P channel(occurs when stress tested passing /dev/random to the channel).

firmware: qcom: scm: Return -EOPNOTSUPP for unsupported SHM bridge enabling
When enabling SHM bridge, QTEE returns 0 and sets error 4 in result to
qcom_scm for unsupported platforms. Currently, tzmem interprets this as
an unknown error rather than recognizing it as an unsupported platform.
Error log:
[ 0.177224] qcom_scm firmware:scm: error (____ptrval____): Failed to enable the TrustZone memory allocator
[ 0.177244] qcom_scm firmware:scm: probe with driver qcom_scm failed with error 4
To address this, modify the function call qcom_scm_shm_bridge_enable()
to remap result to indicate an unsupported error. This way, tzmem will
correctly identify it as an unsupported platform case instead of
reporting it as an error.

firmware: arm_scmi: Reject clear channel request on A2P
The clear channel transport operation is supposed to be called exclusively on the P2A channel from the agent, since it relinquishes the ownership of the channel to the platform, after this latter has initiated some sort of P2A communication. Make sure that, if it is ever called on a A2P, is logged and ignored.

firmware: arm_scmi: Fix slab-use-after-free in scmi_bus_notifier()
The scmi_dev->name is released prematurely in __scmi_device_destroy(),
which causes slab-use-after-free when accessing scmi_dev->name in
scmi_bus_notifier(). So move the release of scmi_dev->name to
scmi_device_release() to avoid slab-use-after-free.

firmware: microchip: auto-update: fix poll_complete() to not report spurious timeout errors
fw_upload's poll_complete() is really intended for use with
asynchronous write() implementations - or at least those where the
write() loop may terminate without the kernel yet being aware of whether
or not the firmware upload has succeeded. For auto-update, write() is
only ever called once and will only return when uploading has completed,
be that by passing or failing. The core fw_upload code only calls
poll_complete() after the final call to write() has returned.
However, the poll_complete() implementation in the auto-update driver
was written to expect poll_complete() to be called from another context,
and it waits for a completion signalled from write(). Since
poll_complete() is actually called from the same context, after the
write() loop has terminated, wait_for_completion() never sees the
completion get signalled and always times out, causing programming to
always report a failing.
Since write() is full synchronous, and its return value will indicate
whether or not programming passed or failed, poll_complete() serves no
purpose and can be cut down to simply return FW_UPLOAD_ERR_NONE.

Arm SCMI fixes for v6.12
Couple of fixes to address the issues found and reported on Broadcom STB platforms following the recent refactor of all the SCMI transports as standalone drivers. One of the issue is that the effective timeout value is much less than the intended value due to the way mailbox messages are queues in the mailbox framework. Since we block or serialise the shmem access anyway, there is no point in utilizing mailbox queues. The issue is fixed with exclusive lock on the channel when sending the message. The other issues is actually non-issue for upstream, but the workaround is just changing the link order of the transport drivers which enables Broadcom STB platforms to run both upstream and custom downstream kernel without any device tree changes. So pushing this to help them test upstream seamlessly as it has no practical or theoretical impact for others. There is also a fix to address possible double freeing of the name string in scmi_debugfs_common_cleanup() when devm_add_action_or_reset() fails. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmcOalcACgkQAEG6vDF+ 4pj9LhAAmTLLEGbDAWSGsU/WTGGTcYexmFnDHmHWTNeY435P1wF44aTabA+9ZVBk LZSQWNpduuSyAeQwxCUq3FuPtq2DhHSMZT55fzG4Cbt3+2ujNMHX7dUJC4aEU3U5 1P6PrAhSfvCzUKzF6KVtO0mlBx5+Ar8hayR2owewQpX7hlQV4yzM6lhYvByiRrII LeVD5mmreBe8k4PfUMsLyaY0Bms005HStcbB1ArVkRe5hr3IQ99FQ4Zhp06qqLLY +iqHLSZekGW0HUbtZVYAxJ8IOtgA88iI8B+7TF5iq7/UqxNGzRdSSeI6lrxZk9Qr OmcjrTfp+aohQOj0Fep+hLBj2rAdzAmnLIZMa4seLdY5tgZtoz7schDeqW2We2Uu WELpLgwXzrxeTn/CGXVKGVbB6eunAY0Hjf7NLnqmQe7x/Wt5cRkqpmPJhbMZKu75 iE5nk1CooaN7tBhrZUhqnEFtlN627V/tdqc8klVqnfArz99JA9Ec9ixdopp33sji QXFwM/xe/GfhZE/3+YdvRb0fGVvoWhU+2JvSKmGax4jWQpWSpVR/mD/BwMEH5lDn 8xTG/Bd/J71sHoPAhORdJVVDexNOoNoPIDBi6J5h4DzEvD5juFo5+TnWrXvzxGFy OH8H2Ic2qRTc290qO9oqwyRXZVPmd/46nEzn2oMeil3qvVdrAw0= =NahH -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmcO0w8ACgkQYKtH/8kJ Uif23w//SLRjEL/ZLhH1NuovqXPgvb8fsibMMQRTfyitCBwsxbhYvdy0gGwtZCTq 5eSbXx2O+GOZSRUaDWoEPIJAIuzR5ASjrgUWzjqEVy8diY9X5GO9mbiqByyQnsp3 GJxiemODqhvbvnFBdcedZIn2eUyPapTAAdj9+CCCcxdd71czxbJOb8ek4pVFN3OO fj+iKm6mT7qW7MM/tYsebgP/4oVcA+4Sz+XMjToyJ29vXoA31tWcrumnrMcRGLcy s685Nv8mhDw9ZsMhNbTghSACBslzxo2oQoKSkd0MiP7LmMxbDj9Nx4U+KxAlbR4f 4ZOzfBVkLv/oGwYG+sVAYJEkh2M0V9EurlECTnLg9taq1/bGCEyFjqAZ15EaCRLS T5VcDaXspiYR3glEWc2Ccbjbw3TD9PTUqBYsS8/jSLj6XKtrw1CnGQe5F3i9HCPL gLoHtX5T0fM2qu35ADQT7Xx49nXY+IXLvZBVqiy1lcjhPRrNyV8UYi0xGoTPcu0D 6rukL3VREmrNOJ1kuFc+T6KgWzxPMHwP6Ojiq6+UwiAdlDFOc323RuOeStVjVs34 G5bUNhVKWxCIH29NSR7/ckvLNCDh2DLkfwXuTz4P+foi9dEf2EMRuBSKueAF9ywO IoBJhwCb5o7WfyX5jdGT0UluNvnMjLA9i4qAjLWc7ZDO1PQsjqE= =iRE2 -----END PGP SIGNATURE----- Merge tag 'scmi-fixes-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes Arm SCMI fixes for v6.12 Couple of fixes to address the issues found and reported on Broadcom STB platforms following the recent refactor of all the SCMI transports as standalone drivers.

firmware: arm_scmi: Queue in scmi layer for mailbox implementation
send_message() does not block in the MBOX implementation. This is
because the mailbox layer has its own queue. However, this confuses
the per xfer timeouts as they all start their timeout ticks in
parallel.
Consider a case where the xfer timeout is 30ms and a SCMI transaction
takes 25ms:
| 0ms: Message #0 is queued in mailbox layer and sent out, then sits
| at scmi_wait_for_message_response() with a timeout of 30ms
| 1ms: Message #1 is queued in mailbox layer but not sent out yet.
| Since send_message() doesn't block, it also sits at
| scmi_wait_for_message_response() with a timeout of 30ms
| ...
| 25ms: Message #0 is completed, txdone is called and message #1 is sent
| 31ms: Message #1 times out since the count started at 1ms. Even though
| it has only been inflight for 6ms.

firmware/sysfb: Disable sysfb for firmware buffers with unknown parent
The sysfb framebuffer handling only operates on graphics devices
that provide the system's firmware framebuffer. If that device is
not known, assume that any graphics device has been initialized by
firmware.
Fixes a problem on i915 where sysfb does not release the firmware
framebuffer after the native graphics driver loaded.

ALong with the usual shower of singleton patches, notable patch series in
this pull request are:
"Align kvrealloc() with krealloc()" from Danilo Krummrich. Adds
consistency to the APIs and behaviour of these two core allocation
functions. This also simplifies/enables Rustification.
"Some cleanups for shmem" from Baolin Wang. No functional changes - mode
code reuse, better function naming, logic simplifications.
"mm: some small page fault cleanups" from Josef Bacik. No functional
changes - code cleanups only.
"Various memory tiering fixes" from Zi Yan. A small fix and a little
cleanup.
"mm/swap: remove boilerplate" from Yu Zhao. Code cleanups and
simplifications and .text shrinkage.
"Kernel stack usage histogram" from Pasha Tatashin and Shakeel Butt. This

kstack_1k 3
kstack_2k 188
kstack_4k 11391
kstack_8k 243
kstack_16k 0
which tells us that 11391 processes used 4k of stack while none at all
used 16k. Useful for some system tuning things, but partivularly useful
for "the dynamic kernel stack project".
"kmemleak: support for percpu memory leak detect" from Pavel Tikhomirov.
Teaches kmemleak to detect leaksage of percpu memory.
"mm: memcg: page counters optimizations" from Roman Gushchin. "3
independent small optimizations of page counters".
"mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from David
Hildenbrand. Improves PTE/PMD splitlock detection, makes powerpc/8xx work
correctly by design rather than by accident.
"mm: remove arch_make_page_accessible()" from David Hildenbrand. Some
folio conversions which make arch_make_page_accessible() unneeded.
"mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David Finkel.
Cleans up and fixes our handling of the resetting of the cgroup/process
peak-memory-use detector.
"Make core VMA operations internal and testable" from Lorenzo Stoakes.

soc: driver updates for 6.12
The driver updates seem larger this time around, with changes
is many of the SoC specific drivers, both the custom drivers/soc
ones and the closely related subsystems (memory, bus, firmware,
reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and
power management code. This is the latest variant of one of the
oldest still supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in many
of their drivers to add more features and additional SoC support. Most
of these are somewhat firmware related as the platform has a number of
firmware based interfaces to the kernel. A notable addition here is the
inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly cleanups.
The Arm SCMI firmware driver gets a major rework to modularize
the existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a
number of smaller updates.
The Arm FF-A firmware driver gets a feature update to support
the v1.2 version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring
for Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
mediatek) drivers and their DT bindings.

Merge tag 'soc-drivers-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC driver updates from Arnd Bergmann:
"The driver updates seem larger this time around, with changes is many
of the SoC specific drivers, both the custom drivers/soc ones and the
closely related subsystems (memory, bus, firmware, reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and power
management code. This is the latest variant of one of the oldest still
supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in
many of their drivers to add more features and additional SoC support.
Most of these are somewhat firmware related as the platform has a
number of firmware based interfaces to the kernel. A notable addition
here is the inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly
cleanups.
The Arm SCMI firmware driver gets a major rework to modularize the
existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a number
of smaller updates.
The Arm FF-A firmware driver gets a feature update to support the v1.2
version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring for
Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra,
amlogic, mediatek) drivers and their DT bindings"

efistub/tpm: Use ACPI reclaim memory for event log to avoid corruption
The TPM event log table is a Linux specific construct, where the data produced by the GetEventLog() boot service is cached in memory, and passed on to the OS using an EFI configuration table. The use of EFI_LOADER_DATA here results in the region being left unreserved in the E820 memory map constructed by the EFI stub, and this is the memory description that is passed on to the incoming kernel by kexec, which is therefore unaware that the region should be reserved. Even though the utility of the TPM2 event log after a kexec is questionable, any corruption might send the parsing code off into the weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY instead, which is always treated as reserved by the E820 conversion logic.

Arm SCMI updates for v6.12
Few main features include:
1. SCMI transport as stand-alone drivers
Currently the SCMI transport layer is being built embedded into in
the core SCMI stack. Some of these transports, despite being currently
part of the main SCMI module, are indeed also registered with different
subsystems like optee or virtio, and actively probed also by those.
This leads to a few awkward and convoluted tricks to properly handle
such interactions at boot time in the SCMI stack.
This change adds the new logic to the core SCMI stack so that each
existing transport is transitioned to be a standi-alone driver. With
that all the probe deferral and awkward retries between the SCMI
core stack and the transports has been removed, since no more needed.
2. Support for obtaining transport descriptors from the devicetree
SCMI platform firmwares might have different designs depending on
the platform. Some of the transport descriptors rely on such design.
E.g. the maximum receive channel timeout value might vary depending
on the specific underlying hardware and firmware design choices.
This change adds support for max-rx-timeout-ms property to describe
the transport needs of a specific platform design. It will be extended
in the future to obtain other such hardware/firmware dependent
transport related descriptors.
3. NXP i.MX95 specific SCMI vendor protocol extensions
SCMI specification allows vendor or platform-specific extensions to
the interface. NXP i.MX95 System Manager(SM) that implements SCMI
extends the interface to implement couple of vendor/platform specific
protocol, namely:
a. Battery Backed Module(BBM) Protocol
This protocol is intended provide access to the battery-backed
module. This contains persistent storage (GPR), an RTC, and the
ON/OFF button. The protocol can also provide access to similar
functions implemented via external board components.
b. MISC Protocol for misc settings
This includes controls that are misc settings/actions that must
be exposed from the SM to agents. They are device specific and
are usually define to access bit fields in various mix block
control modules, IOMUX_GPR, and other GPR/CSR owned by the SM.
4. SCMI debug/tracking metrics
Since SCMI involves interaction with the entity(software, firmware
and/or hardware) providing services or features, it is quite useful
to track certain metrics(for pure debugging purposes) like how many
messages were sent or received, were there any failures, what kind
of failures, ..etc. This feature adds support for the same via debugfs.
Apart from these main features, there are some miscellaneous updates, fixes
and cleanups.

firmware: turris-mox-rwtm: Convert rest to devm_* and get rid of driver .remove()
Use devm resource management for driver's mailbox. This allows us to get rid of the driver's .remove() method and the gotos in .probe().

firmware: turris-mox-rwtm: Simplify debugfs code
Simplify debugfs code: do not check for errors, as debugfs errors should be ignored, and use devm action for dropping the debugfs directory.

firmware: turris-mox-rwtm: Don't create own kobject type
In order to create attribute files in /sys/firmware/turris-mox-rwtm, this driver creates it's own kobject type. Simplify this by dropping this own kobject creation, and instead creating standard device attribute files. For backwards compatibility with sysfs ABI, create a symlink /sys/firmware/turris-mox-rwtm, pointing to this device's sysfs directory.
