|
|
- 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
|
|
