Vaibhav, I think you're misunderstanding. The soc-camera framework has been designed to fulfill two tasks: (1) create a standard interface between (SoC) camera hosts and video clients, and (2) to simplify implementation of new camera host drivers by taking a part of common for many SoC camera controllers functionality into the soc-camera core. The first task is being replaced by v4l2-subdev, that's correct. But I so far don't see a compelling reason to obsolete the 2nd task, which would migrate that common functionality into each camera host driver. New camera host driver authors are free to either use or not to use soc-camera. If they think, the functionality provided by soc-camera core fits well with their hardware, they can use it. If they think, it is imposing too many restrictions and their hardware is more complicated, than what soc-camera offers, then they can write a complete v4l2-device driver.
