[PATCH v4 00/29] Metadata series preparation

Hi folks,

This smallish set contains patches that prepare for merging the metadata
series.

There are simple cleanups but also two noteworthy changes: the addition of
the VALIDATE_LATE media link flag and the addition of the new struct
v4l2_subdev_client_info struct to the get_fmt, set_fmt, get_selection and
set_selection pad operation arguments.

The series now begins with a set of imx219 patches, fixes and cleanups
accrued during the conversion of the imx219 driver to use the common raw
sensor model. I wonder if all these should be backported.

The VALIDATE_LATE allows using the link_validate callback as the way to
validate the links connected to the sink pads of video nodes on pipelines
with multiple capture video nodes. Without this flag, the entire pipeline
will be validated at the time of the first streamon, with the V4L2 pixel
(or other) format set on the other capture video nodes at the time,
requiring all formats to be set before starting streaming anywhere. But
this does generally not match with what the userspace would do, hence the
new flag. The patches in the upcoming metadata series version adds the
support for the flag to the IPU6 driver.

The new struct v4l2_subdev_client_info enables passing around file handler
specific client capability information, which is used to differentiate
UAPI between existing users and those that are aware of the new common raw
sensor model. This is effectively required if we want to add support for
the new model to existing raw sensor drivers: the new model is in a direct
conflict with how things worked before the model. There still needs to be
a single driver internal state, the different UAPIs simply offer a
different view to that state. In-kernel users that do not deal with
capabilities just use NULL when calling these ops. This also means that
whatever client capabilities are being used, there may not be a change to
inter-driver interfaces such as get_fmt() when dealing with external pads.

I'm leaving the last Coccinelle-generated patch out this time as it's more
than 200 kiB. The patch can be found here
<URL:<https://git.linuxtv.org/sailus/media_tree.git/log/?h=metadata-pre>.
Patches 19--22 will be squashed together before merging.

The Coccinelle spatch used to generate the 22nd patch is below, as is a
Perl script to generate another Coccinelle patch doing the rest of the
job:

------------------8<----------------------

since v3:

- Include the patch adding v4l2_subdev_get_frame_desc(); compared to the
version posted earlier, this one uses get_fmt() pad op.

- Removed kernel-doc documentation from sub-device ops in drivers. These
comments are redundant.

- Include v4l2_subdev_client_info changes for ov2732 and t4ka3 drivers.

- Fix setting media link flags.

- Fix the condition for skipping early validation (and doing it later).
The old condition sometimes caused the link being validated too early.

since v2:

- Include imx219 driver fixes accrued during imx219 Common Raw Sensor
Model support implementation. This includes fixes to control ranges and
the removal of the rate_factor, among other things.

- Reword documentation of the VALIDATE_LATE link flag.

- Require that VALIDATE_LATE links sink (origin entity in this case) may
have a single pad only.

- Drop the pipe argument from __media_pipeline_validate_one() as the
function doesn't use it.

- Fix MUST_CONNECT flag validation for links that also have VALIDATE_LATE
flag.

- Rename the macros to create wrapper functions, define one for "! defined
CONFIG_MEDIA_CONTROLLER" case as well.

- Call v4l2_subdev_call_waive_fourth() v4l2_subdev_call_drop_fourth() now.

- Comment the link validation code a little better.

- Fix copying the routes in the routing cleanup patch (copy the same
number of routes as before), rename the function doing it well. Make the
new function copy_routes_state_to_routing() to take just routing and
state arguments, for all callers have this information.

- Add a patch bumping the STREAMS sub-device capability bit and document
that bit 0x2 is reserved.

since v1:

- Address compilation issues. I had only tested on arm64 previously.

- Introduce v4l2_subdev_call_ci_state_active(), to call pad ops with
client info argument with active state. Getting around needing a new
function doesn't seem easy (probably requires one more layer of
indirection I'd like to do without).
