Sorry to bump this thread, but any chance on getting this patch (5/8
clk) and (7/8 pinctrl) merged? I do have an SM8150 device myself (Xiaomi
Mi Pad 5) and would benefit from clk and pinctrl drivers. From the
reviews it seems not much work would be required.
Kind regards

Newer Samsung SoCs (including newer Exynos, ExynosAuto, Google Tensor)
still use these IPs, or slightly newer versions of it.
Make these drivers available on these platforms by guarding
EXYNOS4/EXYNOS5 specific code behind their configs, and using CCF for
clocks on other platforms.
Tested S3C I2C
This has been dead code for many years now. Remove it.

This set of patches should enable the Samsung I2C drivers to work on
platforms other than EXYNOS4/EXYNOS5.
This has been tested on Exynos7885 with the S3C I2C driver.
With the clocks for it implemented in it's driver, this should also
enable S3C I2C to work on Exynos850.
While at it, clean up som

On FDT platforms the APs are brought out of reset using the spin-table
as defined in the DT. On ACPI enabled platforms there's no FDT, thus
enable the ARMV8_MULTIENTRY to use the ACPI parking protocol instead.

When ACPI is enabled over FDT the APs cannot be brought out of reset
by the OS using the "FDT spin-table" mechanism, as no FDT is provided
to the OS. The APs must be released out of reset in u-boot and then
brought up in an ACPI compliant fashion.
When ARMV8_MULTIENTRY is specified the APs are rel
On Arm platforms that use ACPI they cannot rely on the "spin-table"
CPU bringup usually defined in the FDT. Thus implement the
'ACPI Multi-processor Startup for ARM Platforms', also referred to as
'ACPI parking protocol'.
The ACPI parking protocol works similar to the spin-table mechanism, but
