The series includes changes for the mei driver: - add ability to use polling instead of interrupts - add ability to use extended timeouts - setup extended operational memory for GSC The series includes changes for the i915 driver: - allocate extended operational memory for GSC - GSC on XeHP SDV offsets and definitions Greg KH, please review and ACK the MEI patches. (The patch 13 is one that you asked to change in prev version) We are pushing these patches through gfx tree as the auxiliary device belongs there. V2: rebase over merged DG1 series and DG2 enablement patch, fix commit messages V3: rebase over latest tip V4: add missed changelog in pxp dbugfs patch 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.
