Subject: [PATCH] drm/vc4: dsi: Add support for DSI0
|
|
|
|
Commit 4b265fe11fad4234b12d92dd8091f9aa0c878eea upstream.
|
|
|
|
DSI0 was partially supported, but didn't register with the main
|
|
driver, and the code was inconsistent as to whether it checked
|
|
port == 0 or port == 1.
|
|
|
|
Add compatible string and other support to make it consistent.
