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
