Add new DT bindings for new MXSFB driver that is using the OF graph to parse the video output structure instead of hard-coding the display properties into the MXSFB node. The old MXSFB fbdev driver bindings are preserved in the same file in the "Old bindings" section.

* Freescale MXS LCD Interface (LCDIF)
|
|
|
|
New bindings:
|
|
=============
|
|
Required properties:
|
|
- compatible: Should be "fsl,imx23-lcdif" for i.MX23.
|
|
Should be "fsl,imx28-lcdif" for i.MX28.
|
|
Should be "fsl,imx6sx-lcdif" for i.MX6SX.
|
|
- reg: Address and length of the register set for LCDIF
|
|
- interrupts: Should contain LCDIF interrupt
|
|
- clocks: A list of phandle + clock-specifier pairs, one for each
|
|
entry in 'clock-names'.
|
|
- clock-names: A list of clock names. For MXSFB it should contain:
|
|
- "pix" for the LCDIF block clock
|
|
- (MX6SX-only) "axi", "disp_axi" for the bus interface clock
|
|
|
|
Required sub-nodes:
|
|
- port: The connection to an encoder chip.
|
|
|
|
Example:
|
|
|
|
lcdif1: display-controller@2220000 {
|
|
compatible = "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";
|
|
reg = <0x02220000 0x4000>;
|
|
interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&clks IMX6SX_CLK_LCDIF1_PIX>,
|
|
<&clks IMX6SX_CLK_LCDIF_APB>,
|
|
<&clks IMX6SX_CLK_DISPLAY_AXI>;
|
|
clock-names = "pix", "axi", "disp_axi";
|
|
|
|
port {
|
|
parallel_out: endpoint {
|
|
remote-endpoint = <&panel_in_parallel>;
|
|
};
|
|
};
|
|
};
