Subject: [PATCH] drm/amd/pm: Remove arcturus min power limit
Caution: This message originated from an External Source. Use proper caution when opening attachments, clicking links, or responding.
As per power team, there is no need to impose a lower bound on arcturus power limit. Any unreasonable limit set will result in frequent throttling.
