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
