[PATCH 0/4] PM_PME support on display hotplug

[Vinod Govindapillai <vinod.govindapillai@intel.com>]

Introduce PME support for PME capable devices and avoid
HPD polling on runtime suspend. For PME capable devices
HPD will trigger PME which will wakeup the system. And
rest of the runtime resume call is same as before.

Vinod Govindapillai (4):
  drm/i915/hpd: plumb keep_hpd through irq reset
  drm/xe/pm: plumb PME capability to runtime suspend handler
  drm/xe/pm: allow the device to signal PME from D3hot
  drm/i915/display: Avoid HPD polling if the device is PME capable
