Currently the driver exposes a non-functional graph since the pad links are created and the subdev dev nodes are registered in the v4l2 async .complete callback. Instead, these operations should be done in the .bound callback. Patch #1 just adds a v4l2_device_register_subdev_node() function to allow registering a single device node for a subdev of a v4l2 device. Patch #2 moves the logic of the ipu3-cio2 .complete callback to the .bound callback. The .complete callback is just removed since is empy after that.
