[PATCH REPOST v6 0/8] ARM64: juno: add SCPI mailbox protocol, clock and CPUFreq support

[Sudeep Holla]

Hi ARM-SoC guys,

Olof had confused this with PSCI[0]. I assume the confusion is now
resolved ? I have now rebased the series on top of v4.3-rc1 and just
resending them again.

Please pull this series for v4.4

You can access it from:
	git://linux-arm.org/linux-skn.git juno_dvfs

BUT the ARM external git repository is still unreliable and hence I am
avoiding pull request. Can I request to pull it from the mails directly
instead ? Extremely sorry for the inconvenience.

Regards,
Sudeep

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 CPU DVFS on
     ARM64 JUNO development platforms.

The SCPI protocol document is available @[1]
