media: v4l2-async: Improve v4l2_async_notifier_add_*_subdev() API

2021-02-06T08:18:53+00:00

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.

media: v4l2-async: Clean v4l2_async_notifier_add_fwnode_remote_subdev

2021-02-06T07:40:36+00:00

Change v4l2_async_notifier_add_fwnode_remote_subdev semantics
so it allocates the struct v4l2_async_subdev pointer.

This makes the API consistent: the v4l2-async subdevice addition
functions have now a unified usage model. This model is simpler,
as it makes v4l2-async responsible for the allocation and release
of the subdevice descriptor, and no longer something the driver
has to worry about.

On the user side, the change makes the API simpler for the drivers
to use and less error-prone.

Pull media fixes from Mauro Carvalho Chehab:

 - a V4L2 core regression at videobuf2 when checking for single-plane
   dmabuf

 - a change at uAPI header v4l2-subdev.h, fixing a breakage as BIT()
   macro is not available in userspace

 - fix some regressions at RC core due to the usage of microseconds
   everywhere on it

 - a fix for a race condition at RC core

 - a rename on a newly-introduced kAPI symbol (v4l2_get_link_rate),
   currently used only by a single driver

 - Regression fixes for rcar-vin, cedrus, ite-cir, hantro, css, venus,
   and cec drivers.

media: imx6-mipi-csi2: Call remote subdev get_mbus_config to get active lanes

2021-01-27T13:43:36+00:00

Currently, the CSI2 subdevice is using the data-lanes from the
neareast endpoint to config the CSI2 lanes.

While this may work, the proper way to configure the hardware is
to obtain the remote subdevice in v4l2_async_notifier_operations.bound(),
and then call get_mbus_config using the remote subdevice to get
the active lanes.
