Merge tag 'arm-scpi-for-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into next/drivers
Merge "ARM System Control and Power Interface(SCPI) support" from Sudeep Holla
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
* tag 'arm-scpi-for-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux:
hwmon: Support thermal zones registration for SCP temperature sensors
hwmon: Support sensors exported via ARM SCP interface
firmware: arm_scpi: Extend to support sensors
Documentation: add DT bindings for ARM SCPI sensors
cpufreq: arm_big_little: add SCPI interface driver
clk: scpi: add support for cpufreq virtual device
clk: add support for clocks provided by SCP(System Control Processor)
firmware: add support for ARM System Control and Power Interface(SCPI) protocol
Documentation: add DT binding for ARM System Control and Power Interface(SCPI) protocol
