* Analog Devices ADV748X video decoder with HDMI receiver
The ADV7481 and ADV7482 are multi format video decoders with an integrated
HDMI receiver. They can output CSI-2 on two independent outputs TXA and TXB
from three input sources HDMI, analog and TTL.
Required Properties:
- compatible: Must contain one of the following
- "adi,adv7481" for the ADV7481
- "adi,adv7482" for the ADV7482
- reg: I2C slave address
Optional Properties:
- interrupt-names: Should specify the interrupts as "intrq1", "intrq2" and/or
"intrq3". All interrupts are optional. The "intrq3" interrupt
is only available on the adv7481
- interrupts: Specify the interrupt lines for the ADV748x
The device node must contain one 'port' child node per device input and output
port, in accordance with the video interface bindings defined in
Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
are numbered as follows.
Name Type Port
---------------------------------------
AIN0 sink 0
AIN1 sink 1
AIN2 sink 2
AIN3 sink 3
AIN4 sink 4
AIN5 sink 5
AIN6 sink 6
AIN7 sink 7
HDMI sink 8
TTL sink 9
TXA source 10
TXB source 11
The digital output port nodes must contain at least one endpoint.
Ports are optional if they are not connected to anything at the hardware level.
Example:
video-receiver@70 {
compatible = "adi,adv7482";
reg = <0x70>;
#address-cells = <1>;
#size-cells = <0>;
interrupt-parent = <&gpio6>;
interrupt-names = "intrq1", "intrq2";
interrupts = <30 IRQ_TYPE_LEVEL_LOW>,
<31 IRQ_TYPE_LEVEL_LOW>;
port@7 {
reg = <7>;
adv7482_ain7: endpoint {
remote-endpoint = <&cvbs_in>;
};
};
port@8 {
reg = <8>;
adv7482_hdmi: endpoint {
remote-endpoint = <&hdmi_in>;
};
};
port@a {
reg = <10>;
adv7482_txa: endpoint {
clock-lanes = <0>;
data-lanes = <1 2 3 4>;
remote-endpoint = <&csi40_in>;
};
};
port@b {
reg = <11>;
adv7482_txb: endpoint {
clock-lanes = <0>;
data-lanes = <1>;
remote-endpoint = <&csi20_in>;
};
};
};
