This adds device tree bindings for the Faraday TVE200 IP block. This IP block is present in the Gemini ARM SoC and also in some Grain Media GMxxxx SoCs.

* Faraday TV Encoder TVE200
|
|
|
|
Required properties:
|
|
|
|
- compatible: must be one of:
|
|
"faraday,tve200"
|
|
"cortina,gemini-tvc", "faraday,tve200"
|
|
|
|
- reg: base address and size of the control registers block
|
|
|
|
- interrupts: contains an interrupt specifier for the interrupt
|
|
line from the TVE200
|
|
|
|
- clock-names: should contain "PCLK" for the clock line clocking the
|
|
silicon and "TVE" for the 27MHz clock to the video driver
|
|
|
|
- clocks: contains phandle and clock specifier pairs for the entries
|
|
in the clock-names property. See
|
|
Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
Optional properties:
|
|
|
|
- resets: contains the reset line phandle for the block
|
|
|
|
Required sub-nodes:
|
|
|
|
- port: describes LCD panel signals, following the common binding
|
|
for video transmitter interfaces; see
|
|
Documentation/devicetree/bindings/media/video-interfaces.txt
|
|
This port should have the properties:
|
|
reg = <0>;
|
|
It should have one endpoint connected to a remote endpoint where
|
|
the display is connected.
|
|
|
|
Example:
|
|
|
|
display-controller@6a000000 {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
compatible = "faraday,tve200";
|
|
reg = <0x6a000000 0x1000>;
|
|
interrupts = <13 IRQ_TYPE_EDGE_RISING>;
|
|
resets = <&syscon GEMINI_RESET_TVC>;
|
|
clocks = <&syscon GEMINI_CLK_GATE_TVC>,
|
|
<&syscon GEMINI_CLK_TVC>;
|
|
clock-names = "PCLK", "TVE";
|
|
|
|
port@0 {
|
|
reg = <0>;
|
|
display_out: endpoint {
|
|
remote-endpoint = <&panel_in>;
|
|
};
|
|
};
|
|
};
