1Device-Tree bindings for Atmel's HLCDC (High LCD Controller) MFD driver
2
3Required properties:
4 - compatible: value should be one of the following:
5   "atmel,sama5d3-hlcdc"
6 - reg: base address and size of the HLCDC device registers.
7 - clock-names: the name of the 3 clocks requested by the HLCDC device.
8   Should contain "periph_clk", "sys_clk" and "slow_clk".
9 - clocks: should contain the 3 clocks requested by the HLCDC device.
10 - interrupts: should contain the description of the HLCDC interrupt line
11
12The HLCDC IP exposes two subdevices:
13 - a PWM chip: see ../pwm/atmel-hlcdc-pwm.txt
14 - a Display Controller: see ../drm/atmel-hlcdc-dc.txt

16Example:

18	hlcdc: hlcdc@f0030000 {
19		compatible = "atmel,sama5d3-hlcdc";
20		reg = <0xf0030000 0x2000>;
21		clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>;
22		clock-names = "periph_clk","sys_clk", "slow_clk";
23		interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>;
24		status = "disabled";
25
26		hlcdc-display-controller {
27			compatible = "atmel,hlcdc-display-controller";
28			pinctrl-names = "default";
29			pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb888>;
30			#address-cells = <1>;
31			#size-cells = <0>;
32
33			port@0 {
34				#address-cells = <1>;
35				#size-cells = <0>;
36				reg = <0>;
37
38				hlcdc_panel_output: endpoint@0 {
39					reg = <0>;
40					remote-endpoint = <&panel_input>;
41				};
42			};
43		};

45		hlcdc_pwm: hlcdc-pwm {
46			compatible = "atmel,hlcdc-pwm";
47			pinctrl-names = "default";
48			pinctrl-0 = <&pinctrl_lcd_pwm>;
49			#pwm-cells = <3>;
