Regards, Sudeep The following changes since commit 6ff33f3902c3b1c5d0db6b1e2c70b6d76fba357f: Linux 4.3-rc1 (2015-09-12 16:35:56 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git tags/arm-scpi-for-v4.4 for you to fetch changes up to 68acc77a2d5197141ba376fd8872eccb43bfcd7d: hwmon: Support thermal zones registration for SCP temperature sensors (2015-10-09 11:05:53 +0100) ---------------------------------------------------------------- ARM System Control and Power Interface(SCPI) support It adds support for the following features provided by SCP firmware using different subsystems in Linux: 1. SCPI mailbox protocol driver which using mailbox framework 2. Clocks provided by SCP using clock framework 3. CPU DVFS(cpufreq) using existing arm-big-little driver 4. SCPI based sensors including temperature sensors ---------------------------------------------------------------- Punit Agrawal (4): Documentation: add DT bindings for ARM SCPI sensors firmware: arm_scpi: Extend to support sensors hwmon: Support sensors exported via ARM SCP interface hwmon: Support thermal zones registration for SCP temperature sensors Sudeep Holla (5): Documentation: add DT binding for ARM System Control and Power Interface(SCPI) protocol firmware: add support for ARM System Control and Power Interface(SCPI) protocol clk: add support for clocks provided by SCP(System Control Processor) clk: scpi: add support for cpufreq virtual device cpufreq: arm_big_little: add SCPI interface driver Documentation/devicetree/bindings/arm/arm,scpi.txt | 188 +++++ Documentation/hwmon/scpi-hwmon | 33 + MAINTAINERS | 10 + drivers/clk/Kconfig | 10 + drivers/clk/Makefile | 1 + drivers/clk/clk-scpi.c | 325 +++++++++ drivers/cpufreq/Kconfig.arm | 10 + drivers/cpufreq/Makefile | 1 + drivers/cpufreq/scpi-cpufreq.c | 124 ++++ drivers/firmware/Kconfig | 19 + drivers/firmware/Makefile | 1 + drivers/firmware/arm_scpi.c | 771 +++++++++++++++++++++ drivers/hwmon/Kconfig | 8 + drivers/hwmon/Makefile | 1 + drivers/hwmon/scpi-hwmon.c | 288 ++++++++ include/linux/scpi_protocol.h | 78 +++ 16 files changed, 1868 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/arm,scpi.txt create mode 100644 Documentation/hwmon/scpi-hwmon create mode 100644 drivers/clk/clk-scpi.c create mode 100644 drivers/cpufreq/scpi-cpufreq.c create mode 100644 drivers/firmware/arm_scpi.c create mode 100644 drivers/hwmon/scpi-hwmon.c create mode 100644 include/linux/scpi_protocol.h
