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 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 | 94 ++++++- drivers/devfreq/Kconfig | 10 + drivers/devfreq/Makefile | 1 + drivers/devfreq/mt8183-cci-devfreq.c | 309 +++++++++++++++++++++ drivers/opp/core.c | 63 +++++ include/linux/pm_opp.h | 11 + 8 files changed, 507 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 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
