[PATCH 11/20] drm/amd/display: Enable DCN clock gating for DCN35

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

 



From: Daniel Miess <daniel.miess@xxxxxxx>

[WHY & HOW]
Enable DCN clock gating for DCN35.
Disable DTBCLK gate before link training
and re-enable afterwards
