Hi,

this patch serie implements a simple DRM driver for the ATMEL High end LCD
controller found in the SAMA5 familly. It's based on the tilcdc driver.
It uses the cma_helper for memory and fbdev stuff.
Your comments are welcome !

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.

Supported features:
* the base layer (the main framebuffer)

Tested to show a little tux png, but it's appearing only after 
'echo 0 > /sys/devices/ahb.1/apb.2/f0030000.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.

Best Regards
Tim

* structure to 'easily' add other connectors (it comes from the tilcdc)

On the todo list:
* support overlays as drm_planes
* support for the hardware cursor
* support for the SiI9022 HDMI connector (present on sama5d36ek)
