Required Properties :
|
|
- compatible : Must be "ti,tvp7002"
|
|
|
|
Optional Properties:
|
|
- hsync-active: HSYNC Polarity configuration for the bus. Default value when
|
|
this property is not specified is <0>.
|
|
|
|
- vsync-active: VSYNC Polarity configuration for the bus. Default value when
|
|
this property is not specified is <0>.
|
|
|
|
- pclk-sample: Clock polarity of the bus. Default value when this property is
|
|
not specified is <0>.
|
|
|
|
- sync-on-green-active: Active state of Sync-on-green signal property of the
|
|
endpoint.
|

0 = Normal Operation (Active Low, Default)
|
|
1 = Inverted operation
|
|
|
|
- field-even-active: Active-high Field ID output polarity control of the bus.

|
|
(field 1) and set to logic 0 for an even field (field 0).
|
|
0 = Normal Operation (Active Low, Default)
|
|
1 = FID output polarity inverted
