Tejas Patel e502ff8606 soc: xilinx: Set CAP_UNUSABLE requirement for versal while powering down domain ... 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.
