This way concurrent accesses to the iomem range are handled by the regmap
framework, and each subdevice can safely access HLCDC registers.

The HLCDC (HLCD Controller) IP supports 4 different output mode (RGB444,
RGB565, RGB666 and RGB888) and the pin muxing will depend on the chosen
RGB mode.
Split pin definitions to be able to set pin config according to the
selected mode.

That's great news. I knew there were some work in progress on this
topic, but didn't know it was planned for 3.17.
I'll move to this solution.

Changes since v1:
- replace the backlight driver by a PWM driver
- make use of drm_panel infrastructure
- split driver code in several subsystem: MFD, PWM and DRM
- add support for overlays
- add support for hardware cursor
Boris Brezillon (2):
drm: add Atmel HLCDC Display Controll
version.
At the moment, this driver only implements an RGB connector to interface
with LCD panels, but support for other kind of external devices might be
added later.

Hi,
This is a first review, from someone who's clearly not a DRM/KMS expert
but who already thought about this specific driver :-).
I strongly recommend that you wait for DRM/KMS maintainers and/or
experienced developers reviews before modifying anything ;-).
