-Subject: [PATCH] drm: vc4: Probe DPI/DSI timings from the firmware
-
-For DPI and DSI displays query the firmware as to the configuration
-and add it as the only mode for DRM.
-
-In theory we can add plumbing for setting the DPI/DSI mode from
-KMS, but this is not being added at present as the support frameworks
-aren't present in the firmware.
