Merge tag 'imx-soc-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into arm/soc

i.MX SoC update for 5.10:

- A series from Fabio Estevam to remove legacy non-DT i.MX platforms
  support and related board files. This is a natural move, as the
  platforms had been converted to DT for years, and we have not seen
  any users around these legacy non-DT support for a while.
- Enable cpufreq support for i.MX7ULP platform.

MediaTek recently introduced support for the MStar interrupt
controller that is also present in some of their chips as well
as the MStar/Sigmastar chips.

Almost all of the peripheral interrupts go through an instance of
this controller in MStar/SigmaStar Arm v7 chips so we want to select
it if CONFIG_ARCH_MSTARV7 is selected.

Enabling off mode was only reachable deeply hidden
in the debugfs. As powersaving is an important feature,
move the option out of its shady place.
The debugfs file can still be used to override the default.

Use the presence of a device compatible to ti,twl4030-idle or
ti,twl4030-idle-osc-off as an indicator that the board is wired correctly

Samsung S3C24xx and S3C64xx machine code cleanup for v5.10

Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it
also touches files shared with S5Pv210 and Exynos.  This is mostly Arnd
Bergmann work which Krzysztof Kozlowski took over, rebased and polished.

The goal is to cleanup, merge and finally make the Samsung S3C24xx and
S3C64xx architectures multiplatform.  The multiplatform did not happen
yet here - just cleaning up and merging into one arch/arm/mach-s3c
directory.  However this is step forward for multiplatform or at least
to keep this code still maintainable.

This pulls also branch with changes for Samsung SoC sound drivers from
broonie/sound because the cleanups there were part of this series and
all further patches depend on them.
