    drm/i915/skl: Enabling PSR on Skylake · e3d99845
    Sonika Jindal authored
    Mainly taking care of some register offsets, otherwise things are similar to
    hsw. Also, programming ddi aux to use hardcoded values for psr data select.
    
    v2: introduce  EDP_PSR_AUX_BASE macro (Chris)
    v3: Moving to HW tracking for SKL+ platforms, so activating source psr during
    psr_enabling and then avoiding psr entries and exits for each frontbuffer
    updates.
    v4: Using SKL DDI AUX regs instead of changing PSR_AUX regs definition (Rodrigo)

    [danvet: Drop the hunks to short-circuit sw tracking: We'd need to
    push this down one level, and I don't fully trust the test coverage
    yet to do so. So much prefer we pick a whitelist approach for the
    cases we know work correctly.]
