[PATCH 3/5] drm/amd/display: update HDCP DTM immediately after hardware programming
Bhawanpreet Lakha
Bhawanpreet.Lakha at amd.com
Thu Feb 6 21:14:23 UTC 2020
From: Wenjing Liu <Wenjing.Liu at amd.com>
[why]
HDCP DTM needs to be aware of the upto date display topology
information in order to validate hardware consistency.
[how]
update HDCP DTM on update_stream_config call.
