[PATCH v2 0/3] ARM64: dts: cpufreq: mt8173: Migrate mt8173-cpufreq to use OPPv2 bindings

[Pi-Cheng Chen]

This series tries to migrate mt8173-cpufreq driver to use
operating-points-v2 bindings and add support for mt8173-cpufreq driver

v1->v2:
- update dev_pm_opp_of_get_sharing_cpus() to setup bitfield of original CPU
- rename OPP nodes in dts according to OPPv2 bindings in linux-next

[PATCH v2 1/3] PM/OPP: Don't skip cpu_dev->id when setting up cpumask

[Pi-Cheng Chen]

Don't skip cpu_dev->id when setting up cpumask for CPUs that share the
same OPP table. This might be helpful when handling cpumask without the
original CPU bitfield set.

This patch is based on the patch[1] that adds underlying clock MUX for
MT8173 which is needed by mt8173-cpufreq driver but not yet picked.

Not this way. You should just set 'cpumask' to cpumask of cpu_dev->id
at the top of the function.

This patch is now in linux-next through Rafael's pm tree, and it breaks the
arm64 build:

        arm64-defconfig
Error: ../arch/arm64/boot/dts/mediatek/mt8173.dtsi:132.24-25 syntax error


Please revert.

In the future, please send all dts changes through the proper maintainer
channels (-> Mattias -> arm-soc), and make sure they actually build.
