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
