[PATCH 14/17] drm/amdgpu: add si dpm support in amdgpu_atombios
Alex Deucher
alexdeucher at gmail.com
Sat May 14 19:26:26 UTC 2016
From: Maruthi Srinivas Bayyavarapu <Maruthi.Bayyavarapu at amd.com>
v2: renamed _atom_ to _atombios_ for consistency
added ulClockParams to _COMPUTE_MEMORY_ENGINE_PLL_PARAMETERS_V3 and
_COMPUTE_MEMORY_ENGINE_PLL_PARAMETERS_V5 to avoid build break
