6 Required properties:
7  - compatible: value should be "atmel,hlcdc-display-controller"
8  - pinctrl-names: the pin control state names. Should contain "default".
9  - pinctrl-0: should contain the default pinctrl states.
10  - #address-cells: should be set to 1.
11  - #size-cells: should be set to 0.

13 Required children nodes:
14  Children nodes are encoding available output ports and their connections
15  to external devices using the OF graph reprensentation (see ../graph.txt).
16  At least one port node is required.
