I can't see any difference with that.

I used fbv to display the tux. With CONFIG_FRAMEBUFFER_CONSOLE=n the
display stays with a small atmel logo and u-Boot version information. If
i set CONFIG_FRAMEBUFFER_CONSOLE=y, the display is black after kernel
start and fbv just works as expected.

I applied your and Robert's patches on a 3.15-rc2 kernel and tried the
framebuffer device on the sama5d31-ek. Seems to work.

Tested to show a little tux png, but it's appearing only after 
'echo 0 > /sys/devices/ahb.1/apb.2/f003.hlcdc/graphics/fb0/rotate'
is there missing some initializing?

> * a simple panel
> * a backlight driver
Tested to set brightness to 0, 20 and 255. Works.

Thanks for your work.
