Kernel-4.18.0-80.el8_hlcdc-dc

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";

    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>;
    };
};
