Yes, this is patch v3 Change since v2: - Separate cpufreq modification into 3 patches. - Modify dt-binding for more HW information. - Refine cci devfreq coding style. - patch 6 ~ patch 8 are for SVS support > > > 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: cci devfreq register opp notification for SVS support > > > > Stephen Boyd (1): > > PM / OPP: Support adjusting OPP voltages at runtime > > > > .../bindings/devfreq/mt8183-cci-devfreq.txt | 20 ++ > > drivers/cpufreq/cpufreq-dt-platdev.c | 1 + > > drivers/cpufreq/mediatek-cpufreq.c | 88 +++++- > > drivers/devfreq/Kconfig | 10 + > > drivers/devfreq/Makefile | 1 + > > drivers/devfreq/mt8183-cci-devfreq.c | 310 +++++++++++++++++++++ > > drivers/opp/core.c | 78 ++++++ > > include/linux/pm_opp.h | 11 + > > 8 files changed, 517 insertions(+), 2 deletions(-) > > create mode 100644 Documentation/devicetree/bindings/devfreq/mt8183-cci-devfreq.txt > > create mode 100644 drivers/devfreq/mt8183-cci-devfreq.c > > > > -- > > 2.12.5 >
