This patch adds a driver to manage and access global utilities block

and registering soc device are supported. Other guts accesses, such
as reading firmware configuration by default, should eventually be

Commit 7d981405d0fd ("soc: imx8m: change to use platform driver") ever
removed the dependency on bootloader for enabling OCOTP clock.  It
helped to fix a kexec kernel hang issue.  But unfortunately it caused
a regression on CAAM driver and got reverted.

This is the second try to enable the OCOTP clock by directly calling
clock API instead of indirectly enabling the clock via nvmem API.

To enable error reporting for a fabric to CCPLEX, we need to write its
register for enabling error interrupt to CCPLEX during boot and later
clear the error status register after error occurs. If a fabric's
registers are protected and not accessible from CCPLEX, then accessing
the registers will cause CBB firewall error.

Add support to check whether write access from CCPLEX to the registers
of a fabric is not blocked by it's firewall before enabling error
reporting to CCPLEX for that fabric.

The next wakeup timer value needs to be set in always on domain timer

To wakeup the SoC in such scenarios the earliest wakeup time is set in
CONTROL_TCS and the firmware takes care of setting up its own timer in
always on domain with next wakeup time. The timer wakes up the RSC and
sets resources back to wake state.

RSC is part the CPU subsystem and powers off the CPU domains when all
the CPUs and no RPMH transactions are pending from any of the drivers.
The RSC needs to flush the 'sleep' and 'wake' votes that are critical
for saving power when all the CPUs are in idle.

Let's make RSC part of the CPU PM domains, by attaching it to the
cluster power domain. Registering for PM domain notifications, RSC
driver can be notified that the last CPU is powering down. When the last
CPU is powering down the domain, let's flush the 'sleep' and 'wake'
votes that are stored in the data buffers into the hardware and also
write next wakeup in CONTROL_TCS.

1ddb8f6d44 soc/tegra: pmc: Fix dual edge triggered wakes
When a wake event is defined to be triggered on both positive and
negative edge of the input wake signal, it is crucial to know the
current state of the signal when going into suspend. The intended way to
obtain the current state of the wake signals is to read the
WAKE_AOWAKE_SW_STATUS register, which should contains the raw state of
the wake signals.

However, this register is edge triggered, an edge will not be generated
for signals that are already asserted prior to the assertion of
WAKE_LATCH_SW.

To workaround this, change the polarity of the wake level from '0' to
'1' while latching the signals, as this will generate an edge for
signals that are set to '1'.

a2faac3986 ARM: 9263/1: use .arch directives instead of assembler command line flags
Similar to commit a6c30873ee4a ("ARM: 8989/1: use .fpu assembler
directives instead of assembler arguments").

GCC and GNU binutils support setting the "sub arch" via -march=,
-Wa,-march, target function attribute, and .arch assembler directive.

Clang was missing support for -Wa,-march=, but this was implemented in
clang-13.

The behavior of both GCC and Clang is to
prefer -Wa,-march= over -march= for assembler and assembler-with-cpp
sources, but Clang will warn about the -march= being unused.

clang: warning: argument unused during compilation: '-march=armv6k'
[-Wunused-command-line-argument]

Since most assembler is non-conditionally assembled with one sub arch
(modulo arch/arm/delay-loop.S which conditionally is assembled as armv4
based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is
conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the
.arch assembler directive.

Add a few more instances found in compile testing as found by Arnd and
Nathan.

e6c7e6216d soc: mediatek: Add all settings to mtk_mmsys_ddp_dpi_fmt_config func
The difference between MT8186 and other ICs is that when modifying the
output format, we need to modify the mmsys_base+0x400 register to take
effect. So when setting the dpi output format, we need to call
mtk_mmsys_ddp_dpi_fmt_config to set it to MT8186 synchronously.

Commit a071e52f75d1 ("soc: mediatek: Add mmsys func to adapt to dpi
output for MT8186") lacked some of the possible output formats and also
had a wrong bitmask.

Add the missing output formats and fix the bitmask.

While at it, also update mtk_mmsys_ddp_dpi_fmt_config() to use generic
formats, so that it is slightly easier to extend for other platforms.

soc: fsl: qe: Avoid using gpio_to_desc()
The qe gpio driver is a custom API combined GPIO and pin control
driver that exist outside of the pin control subsystem for historical
reasons.

We want to get rid of the old GPIO numberspace, so instead of
calling gpio_to_desc() we get the gpio descriptor for the requested
line from the device tree directly without passing through the
GPIO numberspace, and then we get the gpiochip from the descriptor.

Using the reference counting inside the gpio descriptor we can drop
the reference counting code in this driver. A second gpiod_get()
will not succeed.

To obtain the local hardware offset of the GPIO line, the driver
need to include the header from the gpiolib internals. This isn't
pretty but it is the lesser evil compared to keeping the code
as a roadblock to gpiolib refactoring. A proper solution would be
to rewrite the driver as a real pin control driver with a
built-in gpio_chip.

3a39049f88 soc: qcom: rpmhpd: Use highest corner until sync_state
In some cases the hardware that the bootloader has left configured
depends on RPMH power domains for their operation up until the point
where the related Linux device driver probes and can inherit that
configuration, or power down the hardware gracefully.

Unfortunately as Linux probes the releavant drivers in sequence there
are periods during the Linux boot flow where either the genpd refcount
will reach 0, or worse where the active performance_state votes does not
meet the requirements of the state that the hardware was left in.

One specific example of this is during boot of e.g. SM8150/SC8180X,
where the display clock controller probes, without any particular
performance state needs (to access its registers). This will drop the
MMCX rail to MIN_SVS, which isn't sufficient to sustain the clock rates
that the later probing MDP is configured to. This results in an
unrecoverable system state.

Handle both these cases by keeping the RPMH power-domais that are
referenced voted for highest state, until sync_state indicates that all
devices referencing the RPMH power-domain driver has been probed.
