Subject: [PATCH 0/7] add support for GSC in XeHP SDV platform

Add support for GSC in XeHP SDV (Intel(R) dGPU without display).
 
XeHP SDV GSC controller uses the same hardware settings as DG1, but uses
polling instead of interrupts and runs the firmware in slow pace due to
hardware limitations.

This series should be applied over "Add driver for GSC controller"
patch series.

Greg KH, please review and ACK the MEI patches.
We are pushing all through gfx tree as the device belongs there.

Alexander Usyskin (5):
  drm/i915/gsc: add slow_fw flag to the mei auxiliary device
  drm/i915/gsc: add slow_fw flag to the gsc device definition
  drm/i915/gsc: add GSC XeHP SDV platform definition
  mei: gsc: wait for reset thread on stop
  mei: extend timeouts on slow devices.

Tomas Winkler (1):
  mei: gsc: use polling instead of interrupts

Vitaly Lubart (1):
  drm/i915/gsc: skip irq initialization if using polling
