dt-bindings: adv7180: Convert bindings to json-schema
Convert ADV7180 analog video decoder documentation to json-schema. As the examples in the bindings can be tested add another example to test the more advance adv7180cp binding description.

* Analog Devices ADV7180 analog video decoder family
|
||||
|
||||
The adv7180 family devices are used to capture analog video to different
|
||||
digital interfaces like MIPI CSI-2 or parallel video.
|
||||
|
||||
Required Properties :
|
||||
- compatible : value must be one of
|
||||
"adi,adv7180"
|
||||
"adi,adv7180cp"
|
||||
"adi,adv7180st"
|
||||
"adi,adv7182"
|
||||
"adi,adv7280"
|
||||
"adi,adv7280-m"
|
||||
"adi,adv7281"
|
||||
"adi,adv7281-m"
|
||||
"adi,adv7281-ma"
|
||||
"adi,adv7282"
|
||||
"adi,adv7282-m"
|
||||
|
||||
Device nodes of "adi,adv7180cp" and "adi,adv7180st" 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.
|
||||
|
||||
Port adv7180cp adv7180st
|
||||
-------------------------------------------------------------------
|
||||
Input 0-2 0-5
|
||||
Output 3 6
|
||||
|
||||
The digital output port node must contain at least one endpoint.
|
||||
|
||||
Optional Properties :
|
||||
- powerdown-gpios: reference to the GPIO connected to the powerdown pin,
|
||||
if any.
|
||||
|
||||
|
||||
Example:
|
||||
|
||||
i2c0@1c22000 {
|
||||
...
|
||||
...
|
||||
adv7180@21 {
|
||||
compatible = "adi,adv7180";
|
||||
reg = <0x21>;
|
||||
};
|
||||
...
|
||||
};
