dt-bindings: mxsfb: Add new bindings for the MXSFB driver
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.
|
||||
- reg: Address and length of the register set for lcdif
|
||||
- interrupts: Should contain lcdif interrupts
|
||||
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>;
|
||||
};
|
||||
};
|
||||
};
|
||||
|
||||
