I've been through the same case (now I'm trying to use subdev framework and writing a new device driver based on that) As far as I understand, every v4l2 drivers are moving on subdev framework. But in user space there is nothing changed having access to device and control them. As you know, subdev and int-device is all about how to bind interface(or host?) and device and make them communicated each other. But using subdev device driver with int-device supporting interface (or host) device driver? it won't make any communication. So if you are running out of time with your project, you'd better use old driver of TVP. Like TVP driver in kernel 2.6.28 I suppose. But if you have enough time and wanna be challenging, try to convert in-device based omap3 camera interface driver to subdev supporting one.
