The highlights for the driver support this time are
- Qualcomm platforms gain support for the Qualcomm Secure Execution
Environment firmware interface to access EFI variables on certain
devices, and new features for multiple platform and firmware drivers.
- Arm FF-A firmware support gains support for v1.1 specification features,
in particular notification and memory transaction descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
In particular, this contains portions of the treewide conversion to
use __counted_by annotations and the device_get_match_data helper.

The SOC_BRCMSTB is better depending on ARCH_BRCMSTB as it's
defined for both arm and aarch64 but is more specific to
the actual SoC's dependencies, it'll still get compile tested.

To simplify with maintenance let's move the bcm power-domain drivers to the
new genpd directory. Going forward, patches are intended to be managed
through a separate git tree, according to MAINTAINERS.
While moving the drivers, we end up with a directory for bcm63xx that only
contains a Kconfig file, which seems a bit silly. Let's therefore also move
the Kconfig options into the Kconfig file a directory above, as it allows
us to drop the directory too.

To fix this, iounmap is added when handle error.

Similar to commit a6c30873ee ("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.

The drivers branch for 6.1 is a bit larger than for most releases. Most
of the changes come from SoC maintainers for the drivers/soc subsystem:
- A new driver for error handling on the NVIDIA Tegra
'control backbone' bus.
- A new driver for Qualcomm LLCC/DDR bandwidth measurement
- New Rockchip rv1126 and rk3588 power domain drivers
- DT binding updates for memory controllers, older Rockchip
SoCs, various Mediatek devices, Qualcomm SCM firmware
- Minor updates to Hisilicon LPC bus, the Allwinner SRAM
driver, the Apple rtkit firmware driver, Tegra firmware
- Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
Tegra, Qualcomm, Broadcom, NXP, ...)
There are also some separate subsystem with downstream maintainers that
merge updates this way:
- Various updates and new drivers in the memory controller
subsystem for Mediatek and Broadcom SoCs
- Small set of changes in preparation to add support for FF-A
v1.1 specification later, in the Arm FF-A firmware subsystem
- debugfs support in the PSCI firmware subsystem

now causes a double of_node_put() to be called, once from
setup_hifcpubiuctrl_regs() and another time from brcmstb_biuctrl_init().
Ensure that setup_hifcpubiuctrl_regs() is not calling of_node_put()

The panic notifier of this driver is very simple code-wise, just a
memory write to a special position with some numeric code. But this
is not clear from the semantic point-of-view, and there is no public
documentation about that either.
After discussing this in the mailing-lists [0] and having Florian
explained it very well, document that in the code for the future
generations asking the same questions. Also, while at it, remove
a useless header.

Merge tag 'arm-soc/for-5.20/drivers' of https://github.com/Broadcom/stblinux into arm/drivers
This pull request contains Broadcom SoC drivers updatse for 5.20, please
pull the following:
- Julia fixes a typo in the Broadcom STB legacy power management code
- Liang fixes a device_node reference count leak in the Broadcom STB BIU
driver code error path(s)
- Nicolas and Stefan provide updates to the BCM2835 power management
driver allowing its use on BCM2711 (Raspberry Pi 4) and to enable the
use of the V3D GPU driver on such platforms. This is a merge of an
immutable branch from Lee Jones' MFD tree
- William removes the use of CONFIG_ARCH_BCM_63XX which is removed and
replaces the dependencies with CONFIG_ARCH_BCMBCA which is how all of
the DSL/PON SoCs from Broadcom are now supported in the upstream
kernel.

kernel.h is being used as a dump for all kinds of stuff for a long time.
Here is the attempt to start cleaning it up by splitting out panic and
oops helpers.
There are several purposes of doing this:
- dropping dependency in bug.h
- dropping a loop by moving out panic_notifier.h
- unload kernel.h from something which has its own domain
At the same time convert users tree-wide to use new headers, although for
the time being include new header back to kernel.h to avoid twisted
indirected includes for existing users.

Brahma-B53 and Cortex-A72 CPUs integrated on Broadcom STB SoCs feature a
read-ahead cache that performs cache line size adaptation between the
bus interface unit and the memory controller.
On 32-bit ARM kernels we have to resort to a full featured read-ahead
cache driver under arch/arm/mm/cache-b15-rac.c (CONFIG_CACHE_B15_RAC)
because there are still cache maintenance operations by set/ways/index
that cannot be transparently handled by the ARM Coherency Extension that
the read-ahead cache interfaces to.
The 64-bit ARM kernel however has long deprecated all of those, so this
is simply a one time configuration.
