I woudn't refer to "endpoint" here, perhaps to the specific hardware bus instead ? So it is clear what part of the device it refers to ? > +- pclk-sample: Clock polarity of the endpoint. This description is not very useful, my feeling is that this property is better described in video-interfaces.txt. > +- sync-on-green-active: Active state of Sync-on-green signal property of the > + endpoint, 0/1 for normal/inverted operation respectively. > + > +- field-even-active: Active-high Field ID polarity of the endpoint. I find it hard to understand what this property is about exactly. Not sure if you need to repeat detailed description of the signal polarity properties. Perhaps its sufficient to list which properties are relevant for this device, but I'm not opposed to having supplementary description here. I would just make it more specific to the TVP7002 chip. Also please note that only 'compatible' property is required, all other are optional. And it probably makes sense to specify what are default values for each property when it is not specified. Otherwise the patch looks good. -- Thanks, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
