From 501bcbd1b233edc160d0c770c03747a1c4aa14e5 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 16 Apr 2014 09:52:31 +0200 Subject: [PATCH] drm/tegra: dc - Do not touch power control register Setting the bits in this register is dependent on the output type driven by the display controller. All output drivers already set these properly so there is no need to do it here again.
