[PATCH v1 0/4] add support of cpufreq to mt8173 and mt2712

[PATCH v1 0/4] add support of cpufreq to mt8173 and mt2712

[Andrew-sh Cheng]

This series is based on v4.15-rc1 and [1].

Mediatek projects will use mediate-cpufreq.c as cpufreq driver,
so add mediatek related projects into black list of cpufreq_dt.c

mt8173 and mt2712 both support 2 clusters, and the main difference 
is that mt2712 currently only support fixed voltage.

Of course, DT bindings require ACKs from DT maintainers to be applied.

I didn't knew that we need Acks from DT maintainers for dts files as well? Yeah,
its very much required while defining new bindings for sure.

I will take the dts parts through the Mediatek SoC tree, so you don't have to
worry about them.

Please let me know when you take patch 1 and 2.

Applied now, thanks!

Do you need the branch containing them to be exposed?

Thanks,
Rafael

No, that's not necessary.

I pushed the two patches to v4.15-next/dts64 now.

Re: [PATCH v1 2/4] cpufreq: mediatek: Add mediatek related projects into blacklist

[Sean Wang]

Hi, Rafael and Viresh

Can you kindly guide me how to let the patch also be applied to 4.14 and
4.15 tree? Do I need to submit another patches for them?

These trees really need them. Otherwise, multi_v7_defconfig setup will
cause an occasional hang or unexpected behaviors on related boards as
[1] kernelci reported :-(

You need to send them for stable kernels, just follow the following doc on how
to send patches for stable kernels.
