[RFC 0/3] DRM driver for the ATMEL High end LCD controller

[Jean-Jacques Hiblot]

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 !


Supported features:
* the base layer (the main framebuffer)
* a simple panel
* a backlight driver
* 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)


Jean-Jacques Hiblot (3):
  atmel: drm: added drm driver for the atmel hlcd controller
  atmel: drm: dt: Added DT entry for the atmel hlcdc found in the sama5
  atmel: dt: Add supports for the lcdc support on the sama5d36ek
