6 Many drivers need to communicate with sub-devices. These devices can do all

12 driver with a consistent interface to these sub-devices the
13 :c:type:`v4l2_subdev` struct (v4l2-subdev.h) was created.
15 Each sub-device driver must have a :c:type:`v4l2_subdev` struct. This struct
16 can be stand-alone for simple sub-devices or it might be embedded in a larger
18 low-level device struct (e.g. ``i2c_client``) that contains the device data as
