+From c056e7c76f4949acc006db8929de369ae487b249 Mon Sep 17 00:00:00 2001

+Subject: [PATCH 3135/4256] drm/amdgpu/powerplay: add a new interface to set
+ the mp1 state
+
+This is required for certain cases such as various GPU resets
+(mode1, mode2), BACO, shutdown, unload, etc. to put the SMU into
+the appropriate state for when the hw is re-initialized.
