From 275f01b2694a52d13c32358d17d594ec9aba55e3 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 3 May 2013 11:49:47 +0200 Subject: [PATCH] drm/i915: PCH_ prefix for transcoder timings While at it, also extract a common helper to copy the timings from the cpu transcoder to the pch transcoder. That way it's really explicit how the lpt transcoder is hardcoded. v2: - Re-align #defines properly (Paulo). - Use cpu_transcoder when copying pipe timings (Paulo). - s/intel_pch_transcoder_enable/intel_pch_transcoder_set_timings/ since we already have a pch transcoder enable function, and this is clearer, too. - Fixup 80 char line overflow in intel_display.c. I've opted to ignore this in i915_reg.h and i915_ums.c since meh.
