Subject: [PATCH AUTOSEL 6.9 07/23] drm/amd/display: add root clock control function pointer to fix display corruption

From: "Xi (Alex) Liu" <xi.liu@....com>

[ Upstream commit de2d1105a3757742b45b0d8270b3c8734cd6b6f8 ]

[Why and how]

External display has corruption because no root clock control function. Add the function pointer to fix the issue.
