2019-03-21drm/amdgpu: revert "XGMI pstate switch initial support"Christian König1-15/+0
This reverts commit 9b638f9751308ae3ae8f28e0c6e9decffd97f5f9. Adding this to the mapping is complete nonsense and the whole implementation looks racy. This patch wasn't thoughtfully reviewed and should be reverted for now.
