|
* ingenic,jz4725b-lcd
|
|
- reg: LCD registers location and length
|
|
- clocks: LCD pixclock and device clock specifiers.
|
|
The device clock is only required on the JZ4740.

Example:
|
|
|
|
panel {
|
|
compatible = "sharp,ls020b1dd01d";
|
|
|
|
backlight = <&backlight>;
|
|
power-supply = <&vcc>;
|
|
|
|
port {
|
|
panel_input: endpoint {
|
|
