* Analog Devices ADV7604/11 video decoder with HDMI receiver
|
||
|
|
|
||
|
|
The ADV7604 and ADV7611 are multiformat video decoders with an integrated HDMI
|
||
|
|
receiver. The ADV7604 has four multiplexed HDMI inputs and one analog input,
|
||
|
|
and the ADV7611 has one HDMI input and no analog input.
|
||
|
|
|
||
|
|
These device tree bindings support the ADV7611 only at the moment.
|
||
|
|
|
||
|
|
Required Properties:
|
||
|
|
|
||
|
|
- compatible: Must contain one of the following
|
||
|
|
- "adi,adv7611" for the ADV7611
|
||
|
|
|
||
|
|
- reg: I2C slave address
|
||
|
|
|
||
|
|
- hpd-gpios: References to the GPIOs that control the HDMI hot-plug
|
||
|
|
detection pins, one per HDMI input. The active flag indicates the GPIO
|
||
|
|
level that enables hot-plug detection.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||

|

|
|
HDMI 0
|
||
|
|
Digital output 1
|
||
|
|
|
||
|
|
The digital output port node must contain at least one endpoint.
|
||
|
|
|
||
|
|
Optional Properties:
|
||
|
|
|
||
|
|
- reset-gpios: Reference to the GPIO connected to the device's reset pin.
|
||
|
|
|
||
|
|
Optional Endpoint Properties:
|
||
|
|
|
||
|
|
The following three properties are defined in video-interfaces.txt and are
|
||
|
|
valid for source endpoints only.
|
||
|
|
|
||
|
|
- hsync-active: Horizontal synchronization polarity. Defaults to active low.
|
||
|
|
- vsync-active: Vertical synchronization polarity. Defaults to active low.
|
||
|
|
- pclk-sample: Pixel clock polarity. Defaults to output on the falling edge.
|
||
|
|
|
||
|
|
If none of hsync-active, vsync-active and pclk-sample is specified the
|
||
|
|
endpoint will use embedded BT.656 synchronization.
|
||
|
|
|

|
|
|
