Maybe ask around. (Not that we actually run userspace on the device).Looking at the list of connector types (and wondering if we're gonna need more when converting existing fbdev drivers to drm drivers), there seem to be two different families of connector types, for 1. transports between CRTC and display (e.g. VGA, DVID, HDMI), 2. transports between CPU and CRTC (e.g. SPI, possibly USB, and the proposed I2C)?
I think I had a similar discussion when we merged the gud driver. gud is a driver for a RasPi-based usb display adapter. My point was that USB is just an internal transport bus, like PCI. But that wasn't convincing. So now we have USB and other busses as connector types.
My preference would be to use a panel type as Daniel suggested; and maybe 'Unknown' for a few special cases.
