Subject: [v4, 0/8] Add cpufreq and cci devfreq for mt8183, and SVS support
Date: Tue, 13 Aug 2019 21:31:45 +0800 [thread overview]
Message-ID: <1565703113-31479-1-git-send-email-andrew-sh.cheng@mediatek.com> (raw)
From: "Andrew-sh.Cheng" <andrew-sh.cheng@mediatek.com>
MT8183 supports CPU DVFS and CCI DVFS, and LITTLE cpus and CCI are in the same voltage domain.
So, this series is to add drivers to handle the voltage coupling between CPU and CCI DVFS.
For SVS support, add OPP_EVENT_ADJUST_VOLTAGE and corresponding reaction.
Change since v3:
- modify example of dt-binding
- change rcu implementation in Support adjusting OPP patch
- Add mutex init in cpufreq driver
Andrew-sh.Cheng (7):
cpufreq: mediatek: change to regulator_get_optional
cpufreq: mediatek: add clock enable for intermediate clock
cpufreq: mediatek: Add support for mt8183
dt-bindings: devfreq: add compatible for mt8183 cci devfreq
devfreq: add mediatek cci devfreq
cpufreq: mediatek: add opp notification for SVS support
devfreq: mediatek: cci devfreq register opp notification for SVS
support
