2021-02-06media: v4l2-async: Improve v4l2_async_notifier_add_*_subdev() APILaurent Pinchart
The functions that add an async subdev to an async subdev notifier take as an argument the size of the container structure they need to allocate. This is error prone, as passing an invalid size will not be caught by the compiler. Wrap those functions in macros that take a container type instead of a size, and cast the returned pointer to the desired type. The compiler will catch mistakes if the incorrect type is passed to the macro, as the assignment types won't match.

2021-02-06media: st-mipid02: Use v4l2_async_notifier_add_fwnode_remote_subdevEzequiel Garcia
The use of v4l2_async_notifier_add_subdev will be discouraged. Drivers are instead encouraged to use a helper such as v4l2_async_notifier_add_fwnode_remote_subdev. This fixes a misuse of the API, as v4l2_async_notifier_add_subdev should get a kmalloc'ed struct v4l2_async_subdev, removing some boilerplate code while at it. Use the appropriate helper v4l2_async_notifier_add_fwnode_remote_subdev, which handles the needed setup, instead of open-coding it.

2019-06-24media: st-mipid02: add support of V4L2_CID_LINK_FREQHugues Fruchet
Ask device connected on sink pad for link frequency in order to configure CLK_LANE_REG1 (ui_x4). If not available, ask for pixel rate information to compute it. This is needed to deal with compressed format such as JPEG where number of bits per pixel is unknown: computation of link frequency from pixel rate is not possible.
