|
||
|
|
|
||
|
|
The Atmel HLCDC Display Controller is subdevice of the HLCDC MFD device.
|
||
|
|
See ../mfd/atmel-hlcdc.txt for more details.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: value should be "atmel,hlcdc-display-controller"
|
||
|
|
- pinctrl-names: the pin control state names. Should contain "default".
|
||
|
|
- pinctrl-0: should contain the default pinctrl states.
|
||
|
|
- #address-cells: should be set to 1.
|
||
|
|
- #size-cells: should be set to 0.
|
||
|
|
|
||
|
|
Required children nodes:
|
||
|
|
Children nodes are encoding available output ports and their connections
|
||
|
|
to external devices using the OF graph reprensentation (see ../graph.txt).
|
||
|
|
At least one port node is required.
|
||
|
|
|
||
|
|
