From a1f4efe4416dbd8d58486e60752f3a8145aa84c9 Mon Sep 17 00:00:00 2001 From: Patrik Jakobsson Date: Wed, 10 Jul 2013 18:23:29 +0200 Subject: [PATCH] drm/gma500/cdv: Convert to generic gamma funcs There is a slight difference in how we pick the palette register in the generic function but we should be ok as long as psb_intel_crtc->pipe and the register map is sane.
