   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.
  12
  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.
