regmap: kunit: Add coverage of spinlocked regmaps
By default regmap uses a mutex to protect the regmap but we also support
other kinds of locking, including spinlocks, which can have an impact
especially around allocations. Ensure that we are covering the spinlock
case by running tests configured using fast I/O, this causes the core to
use a spinlock instead of a mutex. Running every single test would be
redundant but cover most of them.

41df03900d thermal/drivers/imx: Remove __maybe_unused notations
Replace SET_RUNTIME_PM_OPS()/SET SYSTEM_SLEEP_PM_OPS() with their modern
RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() alternatives.

The combined usage of pm_ptr() and RUNTIME_PM_OPS/SYSTEM_SLEEP_PM_OPS()
allows the compiler to evaluate if the runtime suspend/resume() functions
are used at build time or are simply dead code.

This allows removing __maybe_unused notations from the suspend/resume()
functions.

d5714524fc thermal/drivers/sprd: Use devm_clk_get_enabled() helpers
The devm_clk_get_enabled() helpers:
    - call devm_clk_get()
    - call clk_prepare_enable() and register what is needed in order to
     call clk_disable_unprepare() when needed, as a managed resource.

This simplifies the code and avoids the calls to clk_disable_unprepare().

b779bbb9df thermal/drivers/brcmstb_thermal: Simplify with dev_err_probe()
dev_err_probe() is used to log an error message during the probe process
of a device.

It can simplify the error path and unify a message template.

Using this helper is totally fine even if err is known to never
be -EPROBE_DEFER.

The benefit compared to a normal dev_err() is the standardized format
of the error code, it being emitted symbolically and the fact that
the error code is returned which allows more compact error paths.

e9482dc50a gpio: mpc8xxx: Add wake on GPIO support
The mpc8xxx GPIO can generate an interrupt on state change. This
interrupt can be used to wake up the device from its sleep state if
enabled to do so. Add required support to the driver so that the GPIO
can be used in this way.

In order for the GPIO to actually function in this way, it is necessary
to also set the GPIO bit in the RCPM. This can be done via the device
tree fsl,rcpm-wakeup property.

e870563243 drm/i915: Fix readout degamma_lut mismatch on ilk/snb
On ilk/snb the pipe may be configured to place the LUT before or
after the CSC depending on various factors, but as there is only
one LUT (no split mode like on IVB+) we only advertise a gamma_lut
and no degamma_lut in the uapi to avoid confusing userspace.

This can cause a problem during readout if the VBIOS/GOP enabled
the LUT in the pre CSC configuration. The current code blindly
assigns the results of the readout to the degamma_lut, which will
cause a failure during the next atomic_check() as we aren't expecting
anything to be in degamma_lut since it's not visible to userspace.

Fix the problem by assigning whatever LUT we read out from the
hardware into gamma_lut.

59d3cfdd7f drm/i915: Do not attempt to load the GSC multiple times
If the GSC FW fails to load the GSC HW hangs permanently; the only ways
to recover it are FLR or D3cold entry, with the former only being
supported on driver unload and the latter only on DGFX, for which we
don't need to load the GSC. Therefore, if GSC fails to load there is no
need to try again because the HW is stuck in the error state and the
submission to load the FW would just hang the GSCCS.

Note that, due to wa_14015076503, on MTL the GuC escalates all GSCCS
hangs to full GT resets, which would trigger a new attempt to load the
GSC FW in the post-reset HW re-init; this issue is also fixed by not
attempting to load the GSC FW after an error.

cdcf626314 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.

Arm FF-A updates for v6.12

The main addition this time is the basic support for FF-A v1.2
specification which includes support for newly added:
1. FFA_MSG_SEND_DIRECT_{REQ,RESP}2
2. FFA_PARTITION_INFO_GET_REGS
3. FFA_YIELD support in direct messaging

Apart from these, the changes include support to fetch the Rx/Tx buffer
size using FFA_FEATURES, addition of the FF-A FIDs for v1.2 and some
coding style cleanups.

487b1b32e3 reset: eyeq: add platform driver
Add Mobileye EyeQ reset controller driver, for EyeQ5, EyeQ6L and EyeQ6H
SoCs. Instances belong to a shared register region called OLB and gets
spawned as auxiliary device to the platform driver for clock.

There is one OLB instance for EyeQ5 and EyeQ6L. There are seven OLB
instances on EyeQ6H; three have a reset controller embedded:
 - West and east get handled by the same compatible.
 - Acc (accelerator) is another one.

Each instance vary in the number and types of reset domains.
Instances with single domain expect a single cell, others two.

Switch from one sub-node per functionality in the system-controller to a
single node representing the entire OLB instance. This is the
recommended approach for controllers handling many different
functionalities; it is a single controller and should be represented by
a single devicetree node.

The reset bindings is removed and all properties will be described by:

a05f87270e reset: core: add get_device()/put_device on rcdev
Since the rcdev structure is allocated by the reset controller drivers
themselves, they need to exists as long as there is a consumer. A call to
module_get() is already existing but that does not work when using
device-tree overlays. In order to guarantee that the underlying reset
controller device does not vanish while using it, add a get_device() call
when retrieving a reset control from a reset controller device and a
put_device() when releasing that control.
