Kernel-4.18.0-80.el8_mxsfb

  • Freescale MXS LCD Interface (LCDIF)

New bindings:

Required properties:

  • compatible: Should be “fsl,imx23-lcdif” for i.MX23.
      Should be "fsl,imx28-lcdif" for i.MX28.
      Should be "fsl,imx6sx-lcdif" for i.MX6SX.
    
  • reg: Address and length of the register set for LCDIF
  • interrupts: Should contain LCDIF interrupt
  • clocks: A list of phandle + clock-specifier pairs, one for each
      entry in 'clock-names'.
    
  • clock-names: A list of clock names. For MXSFB it should contain:
    • “pix” for the LCDIF block clock
    • (MX6SX-only) “axi”, “disp_axi” for the bus interface clock

Required sub-nodes:

  • port: The connection to an encoder chip.

Example:

lcdif1: display-controller@2220000 {
    compatible = "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";
    reg = <0x02220000 0x4000>;
    interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>;
    clocks = <&clks IMX6SX_CLK_LCDIF1_PIX>,
         <&clks IMX6SX_CLK_LCDIF_APB>,
         <&clks IMX6SX_CLK_DISPLAY_AXI>;
    clock-names = "pix", "axi", "disp_axi";

    port {
        parallel_out: endpoint {
            remote-endpoint = <&panel_in_parallel>;
        };
    };
};

Deprecated bindings:

Required properties:

  • compatible: Should be “fsl,imx23-lcdif” for i.MX23.
      Should be "fsl,imx28-lcdif" for i.MX28.
    
  • reg: Address and length of the register set for LCDIF
  • interrupts: Should contain LCDIF interrupts
  • display: phandle to display node (see below for details)
  • display node

Required properties:

  • bits-per-pixel: <16> for RGB565, <32> for RGB888/666.
  • bus-width: number of data lines. Could be <8>, <16>, <18> or <24>.

Required sub-node:

  • display-timings: Refer to binding doc display-timing.txt for details.

Examples:

lcdif@80030000 {
compatible = “fsl,imx28-lcdif”;
reg = <0x80030000 2000>;
interrupts = <38 86>;

display: display {
    bits-per-pixel = <32>;
    bus-width = <24>;

    display-timings {
        native-mode = <&timing0>;
        timing0: timing0 {
            clock-frequency = <33500000>;
            hactive = <800>;
            vactive = <480>;
            hfront-porch = <164>;
            hback-porch = <89>;
            hsync-len = <10>;
            vback-porch = <23>;
            vfront-porch = <10>;
            vsync-len = <10>;
            hsync-active = <0>;
            vsync-active = <0>;
            de-active = <1>;
            pixelclk-active = <0>;
        };
