Subject: [PATCH v5 0/9] cpufreq: mediatek: Cleanup and support MT8183 and MT8186
Date: Wed, 4 May 2022 21:05:31 +0800 [thread overview]
Message-ID: <20220504130540.5902-1-rex-bc.chen@mediatek.com> (raw)
Cpufreq is a DVFS driver used for power saving to scale the clock frequency
and supply the voltage for CPUs. This series do some cleanup for MediaTek
cpufreq drivers and add support for MediaTek SVS[2] and MediaTek CCI
devfreq[3] which are supported in MT8183 and MT8186.
Changes for v5:
1. Modify the description for the reason we need to use mediatek,cci.
2. Drop [07/14] cpufreq: mediatek: Add .get function.
Changes for V4:
1. Revise drivers from reviewers' suggestion.
2. Fix name of opp table issue.
Changes for V3:
1. Rebased to linux-next-20220414.
2. Drop accepted patches.
3. Drop "cpufreq: mediatek: Use maximum voltage in init stage" because we
make sure the voltage we set is safe for both mediatek cci and cpufreq.
4. Rename cci property to mediatek,cci.
5. Adjust order of cleanup patches.
6. Add new patches for cleanup, handle infinite loop and MT8183 dts.
7. Revise drivers from reviewers' suggestion.
8. Revise commit message of some patches to avoid confusion and misunderstand.
9. Revise "cpufreq: mediatek: Link CCI device to CPU".
We do not return successful to pretend we set the target frequency done
when cci is not ready. Instead, we find and set a safe voltage so that we
can set the target cpufrequency.
Changes for V2:
1. Drop the modification of transforming cpufreq-mediatek into yaml and
only add the MediaTek CCI property for MediaTek cpufreq.
2. Split the original patches into several patches.
