[v1,0/4] dt-bindings: DT Schema variants of atmel lcdc, hlcdc

Message

The following four patches update the bindings for Atmel
LCDC, HLCDC display controllers to DT Schema.

The bindings were re-written in DT Schema format,
and examples adjusted/updated to fit.

This patch-set introduces a new endpoint property in video-interfaces
used to tell if red and blue wiring is reversed.
Red and blue wires are reversed as the LCDC IP natively supports BGR
whereas most SW expects RGB. With the wires reversed the SW thinks
the IP supports RGB.
See more details in the changelog of the patch.

The Atmel lcdc binding deprecate a lot of properties in other
to update it to an up-to-date binding. There are no users of the
updated binding, thats something I work on.

Note a big difference between LCDC and HLCDC.
LCDC has all in one binding (interrupts, pwm, display controller).
HLCDC has individual sub-nodes for the PWM and the display contoller.

When posting an update on the old atmel,lcdc.txt file the feedback
was back then that we did not want the split like done for hlcdc.
And it makes for a simpler binding in this way - so feedback looks right.

Despite that Microchip has purchased Atmel, the atmel name is kept.
Also the files are placed in a directory named atmel/.

Feedback welcome!
