    1 * Freescale MXS LCD Interface (LCDIF)
    2 
    3 New bindings:
    4 =============
    5 Required properties:
    6 - compatible:   Should be "fsl,imx23-lcdif" for i.MX23.
    7                 Should be "fsl,imx28-lcdif" for i.MX28.
    8                 Should be "fsl,imx6sx-lcdif" for i.MX6SX.
    9                 Should be "fsl,imx8mq-lcdif" for i.MX8MQ.
   10 - reg:          Address and length of the register set for LCDIF
   11 - interrupts:   Should contain LCDIF interrupt
   12 - clocks:       A list of phandle + clock-specifier pairs, one for each
   13                 entry in 'clock-names'.
   14 - clock-names:  A list of clock names. For MXSFB it should contain:
   15     - "pix" for the LCDIF block clock
   16     - (MX6SX-only) "axi", "disp_axi" for the bus interface clock
   17 
   18 Required sub-nodes:
   19   - port: The connection to an encoder chip.
   20 
   21 Example:
   22 
   23         lcdif1: display-controller@2220000 {
   24                 compatible = "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";
   25                 reg = <0x02220000 0x4000>;
   26                 interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>;
   27                 clocks = <&clks IMX6SX_CLK_LCDIF1_PIX>,
   28                          <&clks IMX6SX_CLK_LCDIF_APB>,
   29                          <&clks IMX6SX_CLK_DISPLAY_AXI>;
   30                 clock-names = "pix", "axi", "disp_axi";
   31 
   32                 port {
   33                         parallel_out: endpoint {
   34                                 remote-endpoint = <&panel_in_parallel>;
   35                         };
   36                 };
   37         };
