Hi Florian,
I think patches 04/10 ("ARM: dts: bcm2835-rpi: Move firmware-clocks from
bcm2711 to bcm2835"), 07/10 ("ARM: dts: bcm2711-rpi: Add pinctrl-based
multiplexing for I2C0"a), 08/10 ("ARM: dts: bcm2711-rpi-cm4-io: Add RTC on
I2C0") and 09/10 ("ARM: dts: bcm2711-rpi-4-b: Add CAM1 regulator") are
ready for you to merge. This would help reducing further iterations of
this series.
A review from Dave would be nice for 05/10 and 09/10 though.

Please do nudge me if there are patches you specifically want me to review. I'm not directly involved in the camera side at present, so only keeping a passing eye on these patchsets.

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 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]) with a set of patches for the imx219 driver applied on top. For convenience, it can be found in [5]. Note that the ISP driver is getting upstreamed separately. Compared to v7, I have left the imx219 patches out, as they don't need to be bundled with the Unicam driver for review. They will be resubmitted separately. The series starts with four patches that add the Unicam driver (04/10), with new V4L2 pixel formats (01/10 and 02/10) and DT bindings (03/10). The remaining patches cover DT integration (05/10 to 09/10) with a sample DT overlay for the IMX219 camera module (10/10). 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 [6]. For manual testing with media-ctl, corresponding API updates to v4l-utils are available at [7]. While more work is needed to be able to merge the generic metadata API (namely implementing support for the latest API version in media-ctl and v4l2-compliance), I'm 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 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.
