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.
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.
regards, Rahul Sharma.

What I've done to avoid that so far is that the master device registers the drivers for it's output sub-devices before registering it's own device.
I'm not sure to follow you here. The master device doesn't register anything, do you mean the master device driver ? If so, how does the master device driver register its own device ? Devices are not registered by their driver.
sorry, that should have read "master driver registers drivers for it's sub-devices.."
