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]). This new upstream driver is based on the downstream code, extensively reworked to use the new V4L2 APIs. The series is based on v8 of the generic metadata and internal pads patches, rebased on v6.9-rc2. It can be found in my tree in [3]. 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/v8/base: The V4L2 embedded data patches, stripped from the sensor-specific parts - rpi/v6.9/metadata/v8/sensors: The sensor-specific parts of the V4L2 embedded data patches - rpi/v6.9/unicam/next: The Unicam driver, based on the rpi/v6.9/metadata/v8/base branch that it depends on - rpi/v6.9/imx219: Embedded data support for the imx219 driver, based on the rpi/v6.9/metadata/v8/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 v9, I have dropped the patches that have already been merged in -next branches targeting upstream for v6.10. I have also left the sample DT overlay out, moving it to a different branch. The resulting series contains only the patches I would like to merge in 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 [4]. For manual testing with media-ctl, corresponding API updates to v4l-utils have been posted to the linux-media mailing list ([5], [6] and [7]) in multiple series. A consolidated version is available for convenience in a git branch at [8]. With this version I believe we are getting very closed to merging 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 are mostly 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 is planning to send a v9 of the embedded data API soon, which hopefully will be the last version. I will rebase the test branches on top and test the result. I don't expect this will require changes to patches in this series. Below you will find the mandatory v4l2-compliance reports. It requires the v4l-utils updates from [8]. 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.
