Subject: [PATCH 00/12] Add cpufreq and cci devfreq for mt8183, and SVS support
Date: Wed, 20 May 2020 11:42:55 +0800 [thread overview]
Message-ID: <20200520034307.20435-1-andrew-sh.cheng@mediatek.com> (raw)
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, need OPP_EVENT_ADJUST_VOLTAGE and corresponding reaction.
Change since v5:
- Changing dt-binding format to yaml.
- Extending current devfreq passive_governor instead of create a new one.
- Resend depending patches of Sravana Kannan base on kernel-5.7
Andrew-sh.Cheng (6):
cpufreq: mediatek: add clock and regulator enable for intermediate
clock
dt-bindings: devfreq: add compatible for mt8183 cci devfreq
devfreq: add mediatek cci devfreq
opp: Modify opp API, dev_pm_opp_get_freq(), find freq in opp, even it
is disabled
cpufreq: mediatek: add opp notification for SVS support
devfreq: mediatek: cci devfreq register opp notification for SVS
support
Saravana Kannan (6):
OPP: Allow required-opps even if the device doesn't have power-domains
OPP: Add function to look up required OPP's for a given OPP
OPP: Improve required-opps linking
PM / devfreq: Cache OPP table reference in devfreq
PM / devfreq: Add required OPPs support to passive governor
PM / devfreq: Add cpu based scaling support to passive_governor
