* 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. |
|
Should be "fsl,imx8mq-lcdif" for i.MX8MQ. |
|
- 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>; |
|
}; |
|
}; |
|
}; |
