This series adds a smd client for the RPM as well as the regulator driver ontop of this RPM abstraction. It depends on the pending smd patches: https://patchwork.kernel.org/patch/6200611/ Bjorn Andersson (3): mfd: devicetree: bindings: Add Qualcomm SMD based RPM DT binding mfd: qcom-smd-rpm: Driver for the Qualcomm RPM over SMD regulator: qcom: smd: Regulator driver for the Qualcomm RPM .../devicetree/bindings/mfd/qcom-rpm-smd.txt | 136 ++++++++ drivers/mfd/Kconfig | 14 + drivers/mfd/Makefile | 1 + drivers/mfd/qcom-smd-rpm.c | 234 ++++++++++++++ drivers/regulator/Kconfig | 12 + drivers/regulator/Makefile | 1 + drivers/regulator/qcom_smd-regulator.c | 351 +++++++++++++++++++++ include/linux/mfd/qcom-smd-rpm.h | 35 ++ 8 files changed, 784 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/qcom-rpm-smd.txt create mode 100644 drivers/mfd/qcom-smd-rpm.c create mode 100644 drivers/regulator/qcom_smd-regulator.c create mode 100644 include/linux/mfd/qcom-smd-rpm.h -- 1.8.2.2 ^ permalink raw reply [flat|nested] 4+ messages in thread
