Device-Tree bindings for Atmel's HLCDC (High LCD Controller) DRM driver
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.
Example:
hlcdc: hlcdc@f0030000 {
compatible = "atmel,sama5d3-hlcdc";
reg = <0xf0030000 0x2000>;
interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>;
clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>;
clock-names = "periph_clk","sys_clk", "slow_clk";
status = "disabled";
hlcdc-display-controller {
compatible = "atmel,hlcdc-display-controller";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb888>;
#address-cells = <1>;
#size-cells = <0>;
port@0 {
#address-cells = <1>;
#size-cells = <0>;
reg = <0>;
hlcdc_panel_output: endpoint@0 {
reg = <0>;
remote-endpoint = <&panel_input>;
};
};
};
hlcdc_pwm: hlcdc-pwm {
compatible = "atmel,hlcdc-pwm";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lcd_pwm>;
#pwm-cells = <3>;
};
};
