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
