   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.

  21 Example:
  22
  23         lcdif1: display-controller@2220000 {

  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         };
