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 lives 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], [3]).

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

The series is based on the generic metadata ([2]) and internal pads
([3], v9) APIs. It can be found in my tree in [4]. Testing it requires
extra branches, which are also pushed to the same tree, and organized as
follows:

- rpi/v6.9/base: The mainline tag that all the work is based on
  (currently v6.9-rc2)
- rpi/v6.9/backports: DT integration fixes for bcm238x, backported from
  linux-next
- rpi/v6.9/isp/v2: The ISP driver, which is getting upstreamed
  separately
- rpi/v6.9/metadata/v10/base: The V4L2 embedded data patches
- rpi/v6.9/metadata/v10/sensors: The V4L2 internal pads patches
- rpi/v6.9/unicam/next: The Unicam driver, based on the
  rpi/v6.9/metadata/v10/base branch that it depends on
- rpi/v6.9/imx219: Embedded data support for the imx219 driver, based on
  the rpi/v6.9/metadata/v10/sensors branch that it depends on
- rpi/v6.9/merge: A merge of the backports, isp/v2, unicam/next and
  imx219 branches
- rpi/v6.9/overlays: A sample overlay for the imx219 camera sensor
  connected to a Raspberry Pi 4

The series starts with two patches that add new V4L2 pixel formats (1/5
and 2/5), followed by the Unicam DT bindings (3/5) and driver (4/5).
Finally, it ends with DT integration for the Unicam devices (5/5).

Compared to v10, I have rebased the patches on top of the latest version
of the generic metadata series ([2]), to prepare for a merge in
(hopefully) v6.10.

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 [5].
For manual testing with media-ctl, corresponding API updates to
v4l-utils have been posted to the linux-media mailing list ([6]) and
pushed to [7].

With this version I believe we are ready to merge the driver upstream.
Sensor driver changes, which require more work, with their corresponding
V4L2 API extensions, have been split out. The Unicam driver now depends
only on the core part of the embedded data API extensions, which I
believe is ready. Corresponding updates for v4l-utils have been
developed and submitted. This series, along with the libcamera support,
helps validating the new kernel APIs.

Sakari, please feel free to apply this on top of your generic metadata
branch and include it in your pull request for v6.10.

Below you will find the mandatory v4l2-compliance reports. It requires
the v4l-utils updates from [7]. There is a total of 4 warnings, all
related to the imx219 driver. They will be addressed separately, as part
of the effort to add embedded data support to the imx219 driver.
