[PATCH 25/51] drm/amd/powerplay: add Fiji DPM support.
Alex Deucher
alexdeucher at gmail.com
Wed Nov 11 22:18:15 PST 2015
From: Eric Huang <JinHuiEric.Huang at amd.com>
This enabled DPM support for Fiji. DPM is dynamic
clock and voltage scaling.
v2: rename fiji_hwmgr_early_init to fiji_hwmgr_init
v3: (agd) fold in endian fix, additional function addition
