Subject: drm/amdgpu: Check pmops for desired suspend state
X-Git-Tag: microblaze-v5.16~369^2^2~5
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=91e273712ab8dd8c31924ac7714b21e011137e98;p=linux-2.6-microblaze.git

drm/amdgpu: Check pmops for desired suspend state

[Why]
User might change the suspend behaviour from OS.

[How]
Check with pm for target suspend state and set s0ix
flag only for s2idle state.

v2: User might change default suspend state, use target state
v3: squash in build fix
