Panning in the y-direction can be done by simply changing the DMA base address. This code is already in place, but FBIOPAN_DISPLAY will currently fail because ypanstep is 0. Set ypanstep to 1 to indicate that we do support y-panning and also set the necessary acceleration flags on AT91 (AVR32 already have them.) Signed-off-by: Haavard Skinnemoen <redacted> ---
Probably you both (Haavard and Stanislaw) should sign-off this patch. Acked-by: Krzysztof Helt <redacted>
