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. 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 V5: rebase over latest tip fix changelog in pxp dbugfs patch put HAX patch last to the ease of merging 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.
