Subject: RE: [PATCH] drm: add connector and encoder types for MIPI displays

Based on the descriptions of encoder and connector, MIPI has different hardware for both the encoder and the connector than LVDS.  If it is unnecessary to present encoder and connector type information to userspace, then I agree that it could be simplified.  However, with the current implementation, I think it would be misleading to refer to all internal panels as having the same encoder and connector types unless they did in fact share the same hardware encoders and connectors.  

Cheers,

I wonder if this is all really necessary to present to userspace, or if
MIPI/LVDS/et al should just fall under 'internally-connected panel'?

Cheers,
