1Device-Tree bindings for Atmel's HLCDC (High LCD Controller) DRM driver
2
3The Atmel HLCDC Display Controller is subdevice of the HLCDC MFD device.
4See ../mfd/atmel-hlcdc.txt for more details.
5
6Required 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
13Required 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.
