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 - v7 of the generic metadata and internal pads, rebased on v6.8-rc5 ([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. I would like this series to first get a review round, which will likely raise API questions. I will then work on the documentation. As a summary, more work is needed, but I believe we're 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.

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). v4l2-compliance 1.27.0-5180, 64 bits, 64-bit time_t v4l2-compliance SHA: c14579f7e5f5 2024-03-01
