[PATCH 0/4] ARM64: add SCPI mailbox protocol, clock and CPUFreq support

[Sudeep Holla <sudeep.holla@arm.com>]

Hi,

This patch series adds support for:
	1. SCPI(System Control and Power Interface) mailbox protocol
	   driver. It uses ARM MHU mailbox controller driver on Juno
	   but can work with any mailbox controllers using standard
	   mailbox APIs
	2. Add support for clocks provided by SCP firmware through
	   the SCPI interface
	3. Using the existing arm_big_little cpufreq driver and the
	   newly added SCPI clock driver, it also adds support for DVFS
on ARM64 JUNO development platforms.

Regards,
Sudeep
