[Intel-gfx] [PATCH 1/3] drm/i915: Renaming CCK related reg definitions

Vandana Kannan vandana.kannan at intel.com
Thu Aug 7 15:10:01 CEST 2014


Rename the DISPLAY_TRUNK_* and DISPLAY_FREQUENCY_* bits to CCK_... instead
of DISPLAY_... to make it clear they apply to all CCK clock control registers.
Suggested by Ville.
