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- 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
17Required sub-nodes:
18 - port: The connection to an encoder chip.

21
22 lcdif1: display-controller@2220000 {
23 compatible = "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";
24 reg = <0x02220000 0x4000>;
25 interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>;
26 clocks = <&clks IMX6SX_CLK_LCDIF1_PIX>,
27 <&clks IMX6SX_CLK_LCDIF_APB>,
28 <&clks IMX6SX_CLK_DISPLAY_AXI>;
29 clock-names = "pix", "axi", "disp_axi";

31 port {
32 parallel_out: endpoint {
33 remote-endpoint = <&panel_in_parallel>;
34 };
35 };
