So my module does not seem to take account of what i set for lcdif in device tree
Once the kernel has booted i can issue fbset commands
fbset -g 800 480 800 480 32 fbset -t 42000 10 1 10 3 5 5
and the display is the correct size and set to the correct position on the physical lcd
Is there a way to set the frame buffer values in the device tree ?
