The mode parsing code recognizes named modes only if they are explicitly listed in the internal whitelist, which is currently limited to "NTSC" and "PAL". Provide a mechanism for drivers to override this list to support custom mode names. Ideally, this list should just come from the driver's actual list of modes, but connector->probed_modes is not yet populated at the time of parsing.

Like we discussed on IRC, I'm not sure allowing drivers to handle named modes is the right thing to do. Named modes in general were a workaround the fact that we were missing infos in drm_display_mode to describe all the modes. I think we really should focus on addressing that first, and then creating some kind of backward compat layer to create an initial DRM state from a named mode provided on the command line. Maxime
