From 942bdf7f9ebc9a46e3f9b3c235112c0947905453 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 9 Aug 2013 10:05:24 -0400 Subject: drm/radeon/dpm: implement UVD powergating for CI Disable the UVD block when not in use to save power. The block is not actually powergated on CI, but we switch between UVD DPM (where the uvd clocks are adjusted on demand) and clocks off.
