[PATCH 10/14] drm/amd/display: Add boot option to reduce PHY SSC for HBR3

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Hansen Dsouza <Hansen.Dsouza@xxxxxxx>

[Why]
Spread on DPREFCLK by 0.3 percent can have a negative effect on sink
when PHY SSC is also spread by 0.3 percent
[How]
Add boot option for DMU to lower PHY SSC
