  • acfdd1859   firmware: xilinx: Use hash-table for api feature check ... Browse Code »

    Currently array of fix length PM_API_MAX is used to cache
    the pm_api version (valid or invalid). However ATF based
    PM APIs values are much higher then PM_API_MAX.
    So to include ATF based PM APIs also, use hash-table to
    store the pm_api version status.

    This check is done by firmware and returns respective

    This change is done to restrict VPLL use count. It is

  • e502ff860   soc: xilinx: Set CAP_UNUSABLE requirement for versal while powering down domain ... Browse Code »

    For "0" requirement which is used to inform firmware that device is
    not required currently by master, Versal PLM (Platform Loader and
    Manager) which runs on Platform Management Controller and is responsible
    platform management of devices that disables clock, power it down
    and reset the device. genpd_power_off() is being called during runtime
    suspend also. So, if any device goes to runtime suspend state during
    resumes it needs to be re-initialized again. It is possible that
    drivers do not reinitialize device upon resume from runtime suspend
    every time ans so dont want it to be powered down or get reset
    during runtime suspend.

    In Versal PLM new PM_CAP_UNUSABLE capability is added, which disables
    clock only and avoids power down and reset during runtime suspend. Power
    and reset will be gated with core suspend.So, this patch sets
    CAPABILITY_UNUSABLE requirement during gpd_power_off()
    if platform is other than zynqmp.
