OMAPDRM works fine.
Display seems to be running at 30Hz due to the clock speed for 60Hz not working properly.
Brightness needs a correct PWM clock value until that is done it flickers at low brightness.
Touchscreen is MMS136 and it works fine. Already in upstream.
Bluetooth does not work, looks like firmware has some issue (?).
Fuel gauge works fine. The charger driver is WIP, if connected to usb during boot, then only it charges.
OMAP4 has different subsystem (Ducati) for camera which is non free. Probably will never work on mainline.
3D GPU Acceleration
3D acceleration works fine. It crashes sometimes like when opening firefox. Video decoding does not work as it is done by Ducati subsystem.
