Patches have been posted to the linux-media@vger.kernel.org mailing list to add i.MX8MP support to the rkisp1 driver ([1]).

2021-03-03include: linux: Update Linux headers to v5.12-rc1Laurent Pinchart
Update Linux headers to v5.12-rc1, to provide the MEDIA_ENT_F_PROC_VIDEO_ISP entity function. The DRM FourCC and modifiers that were manually added in commits 9db0ed5e2065, 38f2efb05cef and 90c793c6989f are kept. New Intel DRM format modifiers are conflicting with IPU3_FORMAT_MOD_PACKED, which is updated as a result. The V4L2 controls and formats that were manually added in commit 43d81d43fe91 are kept. This causes a conflict in the V4L2 control base for V4L2_CID_USER_BCM2835_ISP_BASE that needs to be resolved in the downstream Raspberry Pi kernel first. The intel-ipu3.h header is manually exported with the scripts/headers_install.sh script. The script complained about a missing "WITH Linux-syscall-note" license extension, which has been worked around manually. The issue has been reported upstream in [1].

Refresh the RkISP1 user-space header to match the latest state in the media-tree [1]. This requires update of symbol names in the RkISP1 IPA but there is no functional change. Unfortunately the upstream header has a few problems that needs to be fixed before it can be used. 1. The SPDX header does not satisfy the Linux scripts/headers_install.sh so the installation step have to be done manually (dropping _UAPI prefix from header include guard). Issue is reported upstream. 2. The BIT() macro is used in the header but unfortunately this macro is not accessible in user-space headers. Fix this by reverting back to open code setting the bit without macro. Fix submitted upstream and acked by maintainer. 1. d7a81a5b07313535 ("media: staging: rkisp1: uapi: remove __packed") 2.

The version of the v4l2-controls.h header file shipped by libcamera had deviated from the upstream one, as it included definitions for v4l2 controls that report camera properties, which were not accepted upstream at the time the header file was updated. Now that the controls definition has been accepted in the master branch of the linux-media kernel tree, update include/linux/v4l2-controls.h with the upstream-accepted definition of the control ids that describe camera properties. The control definition has been imported from the Linux kernel header files generated from the most recent linux-media master branch, at revision ad3a44cbd1b2e ("media: i2c: imx219: Parse and register properties") Instead of updating the whole header, just update the definition of V4L2 controls that describe camera properties.
