    Subject[PATCH v3 0/5] ARM64: juno: add SCPI mailbox protocol, clock and CPUFreq support
    Date
    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 CPU DVFS on
    ARM64 JUNO development platforms.

    The SCPI protocol document is available @[1],[2]

    I am not sure which tree would be appropriate to merge this. The
    clock and cpufreq drivers depend on the SCPI protocol header.

    Changes v2->v3:
    - Minor fix in SCPI driver and added Tixy's reviewed-by tag
    - Updated scpi clock driver to incorporate all the comments from
    Stephen
    - Added Viresh's ack

    Changes v1->v2:
    - Updated the token handling in scpi driver as per Tixy's
    suggestion along with other review comments
    - Removed multiple drivers in scpi clock as Lorenzo suggested
    - Added free_opp_table in scpi-cpufreq as Viresh suggested
    - Separated the DT binding document
    - Moved SCPI protocol driver to drivers/firmware

    Regards,
    Sudeep
