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 - reg:          Address and length of the register set for LCDIF
10 - interrupts:   Should contain LCDIF interrupt
11 - clocks:       A list of phandle + clock-specifier pairs, one for each
12                 entry in 'clock-names'.
13 - clock-names:  A list of clock names. For MXSFB it should contain:
14     - "pix" for the LCDIF block clock
15     - (MX6SX-only) "axi", "disp_axi" for the bus interface clock
16
17 Required sub-nodes:
18   - port: The connection to an encoder chip.

20 Example:
21
22         lcdif1: display-controller@2220000 {
23                 compatible = "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";

33                                 remote-endpoint = <&panel_in_parallel>;
34                         };
35                 };
