+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"
+ "microchip,sam9x60-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>;
+ };
+ };
