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.
