[PATCH 02/13] drm/amd/display: Fix HDCP QUERY Error for eDP and Tiled

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

 



From: Mustapha Ghaddar <mghaddar@xxxxxxx>

[WHY]
For dio_output_encoder ID we are relying on SW concept which is
invisible to HW

[HOW]
Needed to create separate cases for when DPIA and non DPIA for
dio link encoder ID
