Thanks for testing this driver.

Only one issue but not related to your patches, you can't display
quickly the bootup logo since the panel detection takes too much
time.

Yes, actually this is related to the device probe order: the
hlcdc-display-controller device is probed before the simple-panel, thus
nothing is detected on the RGB connector (I use of_drm_find_panel to
check for panel availability) when the display controller is
instantiated. I rely on the default polling infrastructure provided by
the DRM/KMS framework which polls for a new connector every 10s, and
this is far more than you kernel boot time.

Do anyone see a solution to reduce this delay (without changing the
polling interval). I thought we could add a notifier infrastructure to
the DRM panel framework, but I'm not sure this is how you want things
done...

Best Regards,

Boris
