Hello everybody,

This patch series adds a new driver for the BCM2835 (and derivative)
CCP2/CSI2 camera interface named Unicam. This IP core is found in the
VC4-based Raspberry Pi, namely the Pi Zero, Pi 3 and Pi 4.

Camera support for Raspberry Pi 4 currently relies on a downstream
Unicam driver that live in the Raspberry Pi kernel tree ([1]). The
driver uses the V4L2 API, but works around the lack of features in V4L2
to properly support sensor embedded data. Since the Unicam driver
development by Raspberry Pi, some of those features have been merged in
the kernel (namely the V4L2 streams API) or are being developed (namely
generic metadata formats and subdev internal pads), with patches posted
for review on the linux-media mailing list ([2]).

This new upstream driver is based on the downstream code, extensively
reworked to use the new V4L2 APIs.

The series is based on top of a merge of

- v8 of the generic metadata and internal pads, rebased on v6.9-rc1 ([3])
- the downstream ISP driver ported to mainline ([4])

For convenience, it can be found in [5]. Note that the ISP driver is
getting upstreamed separately.

The series starts with five patches that add support for streams and
embedded data to the imx219 driver (01/15 to 05/15). Patches 06/15 to
09/15 then add the Unicam driver, with new V4L2 pixel formats (06/15 and
07/15) and DT bindings (08/15) The remaining patches cover DT
integration (10/15 to 14/15) with a sample DT overlay for the IMX219
camera module (15/15).

The patches have been tested on a Raspberry Pi 4 using an IMX219 camera
module (the Raspberry Pi camera v2), with libcamera. Updates are needed
to libcamera to use the new V4L2 APIs, patches have been posted to [6].
For manual testing with media-ctl, corresponding API updates to
v4l-utils are available at [7].

The changes to the imx219 driver effectively define the interface that
raw sensors should expose to userspace. This needs to be documented
explicitly. When posting v6, I stated that I would like the series to
first get a review round, which will likely raise API questions. and
then work on the documentation. As not many API questions have been
raised yet, I'll give reviewers another chance :-)

As a summary, more work is needed, in particular documenting how to use
the API in raw camera sensor drivers, and implementing support for the
latest generic metadata API in media-ctl and v4l2-compliance. I'm
however happy with the unicam implementation, and I believe we're really
nearing completion. This series, along with the libcamera support, help
validating the new kernel APIs. We have in my opinion reached a point
where we can start converting other sensor drivers from the downstream
Raspberry Pi kernel to the standard APIs for embedded data, as well as
integrating the APIs in the Raspberry Pi 5 CFE driver.

Here's the mandatory v4l2-compliance report. There are 5 errors, which
are caused by v4l2-compliance not supporting the new embedded data APIs
yet. This will be fixed and patches for v4l2-compliance will be
submitted (alongside patches to media-ctl).
