[Hiremath, Vaibhav] Hans, I understand your concerns here. The TVP driver has strong dependency on ISP-Camera driver (Master) and without which it really doesn't make sense atleast for me. So actually I was trying to finish the ISP-Camera with V4L2-int and then migrate everything to the sub-devices. I am working with Sergio to finish this as early as possible.
As far as sub-device framework is concerned, we have taken pro-active steps. If I understand correctly Davinci team here has already started migrating to the sub-device framework and the patches are under review internally. Soon you will see some patches on v4L mailing list for this.
