[PATCH v2 04/12] drm/i915/pvc: Read correct RP_STATE_CAP register

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The SoC registers, including RP_STATE_CAP, have moved to a new location
in GTTMMADR on Ponte Vecchio.  We need to update the register offset
accordingly.
