[Intel-gfx] [PATCH v2 1/2] drm/i915: Move uncore definitions into a separate header
Michal Wajdeczko
michal.wajdeczko at intel.com
Tue May 9 09:20:21 UTC 2017
In order to allow use of e.g. forcewake_domains in a other feature headers
included from the top of i915_drv.h, move all uncore related definitions
into their own header.
v2: move __mask_next_bit macro to utils header (Mika)
