[PATCH 73/89] drm/amd/display: Add DCN3.1 DIO
Alex Deucher
alexander.deucher at amd.com
Wed Jun 2 16:48:52 UTC 2021
From: Nicholas Kazlauskas <nicholas.kazlauskas at amd.com>
Add support for the DIO (Display IO) block of DCN3.1 which controls
legacy HDMI/DP stream/link encoding.
HW Blocks:
+--------+ +--------+
| DIO | | DCCG |
+--------+ +--------+
Includes some updates to core logic for link encoder assignment and
future support for new high bandwidth output.
