Hi Laurent,
CDF will also be helpful in supporting Panels with integrated audio (HDMI/DP) if we can add audio related control operations to display_entity_control_ops. Video controls will be called by crtc in DRM/V4L and audio controls from Alsa.
I knew that would come up at some point :-) I agree with you that adding audio support would be a very nice improvement, and I'm totally open to that, but I will concentrate on video, at least to start with. The first reason is that I'm not familiar enough with ALSA, and the second that there's only 24h per day :-)
Please feel free, of course, to submit a proposal for audio support.
Secondly, if I need to support get_modes operation in hdmi/dp panel, I need to implement edid parser inside the panel driver. It will be meaningful to add get_edid control operation for hdmi/dp.
Even if EDID data is parsed in the panel driver, raw EDID will still need to be exported, so a get_edid control operation (or something similar) is definitely needed. There's no disagreement on this, I just haven't included that operation yet because my test hardware is purely panel-based.
one of (probably many) places that just keeping CDF (CDH? common display helpers..) inside DRM makes life easier :-P
