I'm confused by the part numbers. 7182 or 7280? In any case, I'd just drop the part number from the property name. > > Signed-off-by: Fabio Estevam <festevam@gmail.com> > --- > Documentation/devicetree/bindings/media/i2c/adv7180.yaml | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/Documentation/devicetree/bindings/media/i2c/adv7180.yaml b/Documentation/devicetree/bindings/media/i2c/adv7180.yaml > index bcfd93739b4f..83e47b0c9fa2 100644 > --- a/Documentation/devicetree/bindings/media/i2c/adv7180.yaml > +++ b/Documentation/devicetree/bindings/media/i2c/adv7180.yaml > @@ -35,6 +35,11 @@ properties: > powerdown-gpios: > maxItems: 1 > > + adv,adv7182-force-bt656-4: > + description: > + Indicates that ADV7182 should output a BT.656-4 compatible stream. > + type: boolean > + > port: > $ref: /schemas/graph.yaml#/properties/port > > -- > 2.25.1

Yes, dropping the part number from the property name is less confusing. Will do as suggested in v2. Thanks

Captured NTSC video would be out of sync when using the adv7280 with the BT.656-4 protocol. Certain registers (0x04, 0x31, 0xE6) need to be configured properly to ensure BT.656-4 compatibility. Introduce the 'adv,adv7182-force-bt656-4' property to allow the ADV7280 behavior to be consistent with the ADV7180, where BT.656-4 timing is used.
