This callback can be implemented by subdevice like a MIPI CSI2 receiver, allowing the host driver to gather additional data into frame buffer passed to user space.

This is just an initial, mostly stub implementation. struct v4l2_mbus_frame_desc is intended to be extended with sub-structures specific to a particular hardware media bus.
