From 229fca97437310c04033ce4708c449ecfbb1b90c Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 24 Apr 2014 23:55:09 +0200 Subject: [PATCH] drm/i915: Shovel hw setup code out of hsw_crtc_mode_set Again the same story: This code just transform sw state from the pipe config into hardware state. And again we can't move the pll code, but this time around because the state isn't properly tracked in the pipe config.
