  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
