[PATCH v3 0/3] arm64: dts: exynos: gs101: add cpufreq support

[PATCH v3 0/3] arm64: dts: exynos: gs101: add cpufreq support

[Tudor Ambarus]

Define the CPU clocks and OPPs.

Patch #2 has a dependency on the ACPM clock bindings sent at:
https://lore.kernel.org/linux-samsung-soc/20250903-acpm-clk-v3-1-65ecd42d88c7@linaro.org/

The following error will be seen without the bindings patch:
arch/arm64/boot/dts/exynos/google/gs101.dtsi:10:10: fatal error: dt-bindings/clock/google,gs101-acpm.h: No such file or directory
   10 | #include <dt-bindings/clock/google,gs101-acpm.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Thanks,
ta

Changes in v3:
- the ACPM clock bindings were moved to their own file, update the
  references accordingly.
- Link to v2: https://lore.kernel.org/r/20250827-acpm-dvfs-dt-v2-0-e1d2890d12b4@linaro.org

Changes in v2:
- acpm node becomes a clock provider.
- reword commit message, extend cover letter with info about dependency
  on a bindings patch.
- Link to v1: https://lore.kernel.org/r/20250819-acpm-dvfs-dt-v1-0-4e38b95408c4@linaro.org

[PATCH v3 1/3] arm64: dts: exynos: gs101: add #clock-cells to the ACPM protocol node

[Tudor Ambarus]

Make the ACPM node a clock provider by adding the mandatory
"#clock-cells" property, which allows devices to reference
its clock outputs.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: using specified base-commit c17b750b3ad9f45f2b6f7e6f7f4679844244f0b9

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

That's alright, I described in the cover letter the dependency on the patch
that adds this bindings file. Thanks!
