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. depend on: https://patchwork.kernel.org/patch/11193513/ Change since v4: - Remove redundant code Andrew-sh.Cheng (5): cpufreq: mediatek: add clock enable for intermediate clock 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 .../bindings/devfreq/mt8183-cci-devfreq.txt | 20 ++ drivers/cpufreq/mediatek-cpufreq.c | 92 +++++- drivers/devfreq/Kconfig | 10 + drivers/devfreq/Makefile | 1 + drivers/devfreq/mt8183-cci-devfreq.c | 308 +++++++++++++++++++++ 5 files changed, 429 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/devfreq/mt8183-cci-devfreq.txt create mode 100644 drivers/devfreq/mt8183-cci-devfreq.c
