From: Jesse Barnes Date: Thu, 25 Apr 2013 19:55:02 +0000 (-0700) Subject: drm/i915: move PCH pfit controls into pipe_config X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b074cec8c652f2d273907a4b35239b4766c894ac;p=openwrt%2Fstaging%2Fblogic.git drm/i915: move PCH pfit controls into pipe_config And put the pfit stuff into substructs while we're at it.
