1* Freescale MXS LCD Interface (LCDIF)
2
3New bindings:
4=============
5Required 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
18Required sub-nodes:
19  - port: The connection to an encoder chip.
20
21Example:
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	};
