it contains settings related to AUS mode. This mode sets different
mappings between framebuffer memory and display pixels. It seems that
these mappings were originally defined for displays from AUO.
The only bit from this register that I really need is "AUS mode on/off".
I could put this into the device tree instead of the entire register.
Best regards,
Martin
