Device-Tree bindings for Atmel's HLCDC (High LCD Controller) MFD driver
|
|
|
|
Required properties:
|
|
- compatible: value should be one of the following:
|
|
"atmel,at91sam9n12-hlcdc"
|
|
"atmel,at91sam9x5-hlcdc"
|
|
"atmel,sama5d2-hlcdc"
|
|
"atmel,sama5d3-hlcdc"
|
|
"atmel,sama5d4-hlcdc"
|
|
- reg: base address and size of the HLCDC device registers.
|
|
- clock-names: the name of the 3 clocks requested by the HLCDC device.
|
|
Should contain "periph_clk", "sys_clk" and "slow_clk".
|
|
- clocks: should contain the 3 clocks requested by the HLCDC device.
|
|
- interrupts: should contain the description of the HLCDC interrupt line
|
|
|
|
The HLCDC IP exposes two subdevices:
|
|
- a PWM chip: see ../pwm/atmel-hlcdc-pwm.txt
|
|
- a Display Controller: see ../display/atmel/hlcdc-dc.txt
|
|
|
|
Example:
|
|
|
|
hlcdc: hlcdc@f0030000 {
|
|
compatible = "atmel,sama5d3-hlcdc";
|
|
reg = <0xf0030000 0x2000>;
|
|
clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>;
|
|
clock-names = "periph_clk","sys_clk", "slow_clk";
|
|
interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>;
|
|
|
|
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>;
|
|
};
|
|
};
