Pull SoC driver updates from Arnd Bergmann:
 "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"

soc: samsung: exynos-chipid: Convert to platform remove callback returning void

2023-10-16T20:49:56+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

pmdomain: samsung: Move Kconfig option to the pmdomain subsystem

2023-10-04T21:41:56+00:00

The Kconfig option belongs closer to the corresponding implementation,
hence let's move it from the soc subsystem to the pmdomain subsystem.

soc: samsung: Explicitly include correct DT includes

2023-07-20T09:30:09+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

To simplify with maintenance let's move the samsung power-domain driver to
the new genpd directory. Going forward, patches are intended to be managed
through a separate git tree, according to MAINTAINERS.

soc: samsung: exynos-pmu: Re-introduce Exynos4212 support

2023-05-09T17:49:37+00:00

Support for the Exynos4212 SoC was originally dropped as there were
no boards using it. We will be adding a device that uses it, so add
it back.

This reverts commit c40610198f35e8264f9175dafe74db6288a07eda.

soc: s3c: remove pm-debug hack

2023-01-16T08:26:06+00:00

CONFIG_SAMSUNG_PM_DEBUG was only used on s3c24xx because of the
DEBUG_S3C24XX_UART dependency. Since s3c24xx is now gone, and nobody
ever noticed this option being missing from s3c64xx, it can be safely
removed as well.

ARM: s3c: remove all s3c24xx support

2023-01-16T08:26:05+00:00

The platform was deprecated in commit 6a5e69c7ddea ("ARM: s3c: mark
as deprecated and schedule removal") and can be removed. This includes
all files that are exclusively for s3c24xx and not shared with s3c64xx,
as well as the glue logic in Kconfig and the maintainer file entries.
