A sub-device device node can be registered in user space only if the
CONFIG_VIDEO_V4L2_SUBDEV_API Kconfig option is selected. Currently the
open/close file operations and the ioctl handler have some parts of
their implementations guarded by #if
defined(CONFIG_VIDEO_V4L2_SUBDEV_API), while they are actually not
accessible without a video device node registered to user space.
Guard the whole open, close and ioctl handler and provide stubs if the
VIDEO_V4L2_SUBDEV_API Kconfig option is not selected.
This slightly reduces the kernel size when the option is not selected
and simplifies the file ops and ioctl implementations.
Add to the V4L2 core a function to register device nodes for video
subdevices in read-only mode.
Registering a device node in read-only mode is useful to expose to
userspace the current sub-device configuration, without allowing

media: v4l2: Extend VIDIOC_ENUM_FMT to support MC-centric devices
The VIDIOC_ENUM_FMT ioctl enumerates all formats supported by a video
node. For MC-centric devices, its behaviour has always been ill-defined,
with drivers implementing one of the following behaviours:
- No support for VIDIOC_ENUM_FMT at all
- Enumerating all formats supported by the video node, regardless of the
configuration of the pipeline
- Enumerating formats supported by the video node for the active
configuration of the connected subdevice
The first behaviour is obviously useless for applications. The second
behaviour provides the most information, but doesn't offer a way to find
what formats are compatible with a given pipeline configuration. The
third behaviour fixes that, but with the drawback that applications
can't enumerate all supported formats anymore, and have to modify the
active configuration of the pipeline to enumerate formats.
The situation is messy as none of the implemented behaviours are ideal,
and userspace can't predict what will happen as the behaviour is
driver-specific.
To fix this, let's extend the VIDIOC_ENUM_FMT with a missing capability:
enumerating pixel formats for a given media bus code. The media bus code
is passed through the v4l2_fmtdesc structure in a new mbus_code field
(repurposed from the reserved fields). With this capability in place,
applications can enumerate pixel formats for a given media bus code
without modifying the active configuration of the device.
The current behaviour of the ioctl is preserved when the new mbus_code
field is set to 0, ensuring compatibility with existing userspace. The
API extension is documented as mandatory for MC-centric devices (as
advertised through the V4L2_CAP_IO_MC capability), allowing applications
and compliance tools to easily determine the availability of the
VIDIOC_ENUM_FMT extension.
media: pci: Fill v4l2_fmtdesc with designated initializers
Replace initialization of static const v4l2_fmtdesc instances that
specify every struct member with designated initializers. This allows
not zeroing the reserved fields explicitly, and will avoid a need to
patch these drivers every time a reserved field is repurposed.
Add a video device capability flag to indicate that its inputs and/or
outputs are controlled by the Media Controller instead of the V4L2 API.
When this flag is set, ioctl for enum inputs and outputs are
automatically enabled and programmed to call a helper function.
