From 4aa708f5813fc6cf47a2183c1e6924ca03808062 Mon Sep 17 00:00:00 2001 From: Rex Zhu Date: Thu, 4 Jan 2018 16:42:06 +0800 Subject: [PATCH 3173/4131] drm/amd/pp: Add a new pp feature mask bit for OD feature when this bit was set on module load, driver will allow the user over/under gpu clock and voltage through sysfs. by default, this bit was not set.
