Steve Longerbeam acee6033c5 media: Revert "media: v4l2-fwnode: Add a convenience function for registering subdevs with notifiers"
The users of v4l2_async_register_fwnode_subdev() have switched to
parsing their endpoints and setting up async sub-device lists in their
notifiers locally, without using the endpoint parsing callbacks. There
are no more users of v4l2_async_register_fwnode_subdev() so this
convenience function can be removed.

This reverts commit 1634f0eded.

Steve Longerbeam 0e63a5e4bb media: imx: Parse information from firmware without using callbacks
Instead of using the convenience functions
v4l2_async_notifier_parse_fwnode_endpoints*() or
v4l2_async_register_fwnode_subdev(), parse the input endpoints
and set up the async sub-devices without using callbacks. The drivers
know which ports it must parse and how to handle unconnected remotes,
so it makes the code simpler to transfer control of endpoint parsing
to the driver.

Steve Longerbeam 0d3c81e82d media: v4l2-mc: add v4l2_create_fwnode_links helpers
Add functions to create media links between source and sink subdevices,
based on the fwnode endpoint connections between them:

v4l2_create_fwnode_links_to_pad() - create links from a source subdev to
                                    a single sink pad based on fwnode
                                    endpoint connections.

v4l2_create_fwnode_links() - create all links from a source to sink subdev
                             based on fwnode endpoint connections.

These functions can be used in a sink's v4l2-async notifier subdev
bound callback to make the links from the bound subdev.

that apps can call to determine that it is indeed a V4L2 device, there
is currently no equivalent for v4l-subdev nodes. Adding this ioctl will
solve that, and it will allow utilities like v4l2-compliance to be used
with these devices as well.

SUBDEV_QUERYCAP currently returns the version and capabilities of the
subdevice. Define a capability flag to report if the subdevice is
registered in read-only mode.

Jacopo Mondi fb15db8c00 media: v4l2-subdev: Guard whole fops and ioctl hdlr
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.

Laurent Pinchart e5b6b07a1b 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.

The log_addrs->log_addr_type[i] value is a u8 which is controlled by
the user and comes from the ioctl.  If it's over 31 then that results in
undefined behavior (shift wrapping) and that leads to a Smatch static
checker warning.  We already cap the value later so we can silence the
warning just by re-ordering the existing checks.

I think the UBSan checker will also catch this bug at runtime and
generate a warning.  But otherwise the bug is harmless.

Arnd Bergmann 6c8d0cdd6c media: ti-vpe: avoid gcc-9 warning
gcc warns about empty array declarations, which we get in this driver
when compile-testing without CONFIG_OF:

drivers/media/platform/ti-vpe/cal.c:2194:34: warning: array 'cal_of_match' assumed to have one element
 2194 | static const struct of_device_id cal_of_match[];

Since all users of this driver do need CONFIG_OF anyway, there is no
point in making the array definition conditional to save space, so
just remove the #ifdef and move the array up a little.

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Steve Longerbeam 54ac3fc348 media: imx: utils: Default colorspace to SRGB
The function imx_media_init_mbus_fmt() initializes the imx subdevice
mbus colorimetry to some sane defaults when the subdevice is registered.
Currently it guesses at a colorspace based on the passed mbus pixel
format. If the format is RGB, it chooses colorspace V4L2_COLORSPACE_SRGB,
and if the format is YUV, it chooses V4L2_COLORSPACE_SMPTE170M.

While that might be a good guess, it's not necessarily true that a RGB
pixel format encoding uses a SRGB colorspace, or that a YUV encoding
uses a SMPTE170M colorspace. Instead of making this dubious guess,
just default the colorspace to SRGB.

arch/arm64/boot/dts/rockchip/rk3328-evb.dt.yaml: video-codec@ff350000:

With the conversion of rockchip-vpu.txt to yaml the correct
'interrupt-names' for rk3328 was not included, so add them now.
Also add 'minItems' to 'interrupts'for the completeness.

In selfpath, RGB capture formats are received in the sink pad as YUV
and are converted to RGB only when writing to memory. So the validation
function should accept YUV bus formats with RGB capture encoding.
