GDSCs (Global Distributed Switch Controllers) control switches that supply power to an on-chip power domain and hence can be programmed in SW to safely power collapse and restore power to the respective PDs. They are part of a considerable number of recent QCOM SoCs (This series adds support for msm8974, msm8916 and apq8084 devices) and are part of the Clock control block. The series implements support for GDSC using the genpd framework modelling these as SW controllable power domains. * Patch 3/6 has a dependency on 8916 GCC support series [1] * Client drivers which plan to use GDSC can refer to Documentation/devicetree/bindings/power/power_domain.txt to know how to hook up the power domain for the device through DT * Runtime PM specific documentation can be found in Documentation/power/runtime_pm.txt Changes since v1: * added err checks for regmap apis * added gdsc_register() in gdsc.c [1] https://lkml.org/lkml/2015/3/18/408 Rajendra Nayak (3): clk: qcom: gdsc: Prepare common clk probe to register gdscs clk: qcom: gdsc: Add GDSCs in msm8916 GCC clk: qcom: gdsc: Add GDSCs in apq8084 GCC Stephen Boyd (3): clk: qcom: Add support for GDSCs clk: qcom: gdsc: Add GDSCs in msm8974 GCC clk: qcom: gdsc: Add GDSCs in msm8974 MMCC arch/arm/boot/dts/qcom-apq8084.dtsi | 1 + arch/arm/boot/dts/qcom-msm8974.dtsi | 2 + drivers/clk/qcom/Kconfig | 9 ++ drivers/clk/qcom/Makefile | 1 + drivers/clk/qcom/common.c | 14 ++- drivers/clk/qcom/common.h | 2 + drivers/clk/qcom/gcc-apq8084.c | 38 ++++++ drivers/clk/qcom/gcc-msm8916.c | 46 ++++++++ drivers/clk/qcom/gcc-msm8974.c | 14 +++ drivers/clk/qcom/gdsc.c | 161 ++++++++++++++++++++++++++ drivers/clk/qcom/gdsc.h | 43 +++++++ drivers/clk/qcom/mmcc-msm8974.c | 54 +++++++++ include/dt-bindings/clock/qcom,gcc-apq8084.h | 6 + include/dt-bindings/clock/qcom,gcc-msm8916.h | 8 ++ include/dt-bindings/clock/qcom,gcc-msm8974.h | 3 + include/dt-bindings/clock/qcom,mmcc-msm8974.h | 8 ++ 16 files changed, 409 insertions(+), 1 deletion(-) create mode 100644 drivers/clk/qcom/gdsc.c create mode 100644 drivers/clk/qcom/gdsc.h -- QUALCOMM INDIA, on behalf of Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
