Other Parts Discussed in Thread: TFP410
I am trying to get the tilcdc panel driver working with the DRM subsystem but without the TFP410. We have the Sitara connected directly to a TFT panel, like on the EVMSK board - but a different panel. When I boot the board, because there is no TFP410 in the device tree the DRM finds no encoders or connectors:
[drm] Initialized drm 1.1.0 20060810
[ 0.983480] Error: Driver 'tfp410' is already registered, aborting...
[ 0.993494] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

[ 1.133064] [drm] Initialized tilcdc 1.0.0 20121205 on minor 0
Based on this output, I wouldn't expect that the LCD will work - and it doesn't. I assume using the DRM somehow works on the EVMSK, but how? Thanks.
