    Subject[PATCH 00/20] GSC support for XeHP SDV and DG2 platforms
    Date
    Add GSC support for XeHP SDV and DG2 platforms.

    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
    - GSC on DG2 offsets and definitions

    The first six patches of the series are copied from the
    already reviewed series [1] to provide series that
    can be built in CI.
    This series will be rebased and merged only after
    series [1] merge.

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