Add media bus codes introduced by the Mali C55 ISP support to describe
the 20-bit input formats supported by the ISP. This manual addition is
a temporary measure until the kernel driver changes are merged, from
which point this will be managed through the usual merge of the upstream
kernel headers.
Add the following formats
- MEDIA_BUS_FMT_RGB202020_1X60
for processed input formats
https://lore.kernel.org/linux-media/20241106100534.768400-2-dan.scally@ideasonboard.com/
- MEDIA_BUS_FMT_SBGGR20_1X20
MEDIA_BUS_FMT_SGBRG20_1X20
MEDIA_BUS_FMT_SGRBG20_1X20
MEDIA_BUS_FMT_SRGGB20_1X20
for the RAW bayer input format

Patches have been posted to the linux-media@vger.kernel.org mailing list
to add i.MX8MP support to the rkisp1 driver ([1]). As no changes are
expected to the userspace API in future versions of the series, add the
RKISP1_V_IMX8MP version manually to the rkisp1-config.h header already.
Once the patches get merged in the kernel, the changes will trickle down
to libcamera with the next kernel headers update.

The intel-ipu3.h public interface from the kernel does not define how to
parse the statistics for a cell. This had to be identified by a process
of reverse engineering, and later identifying the structures from [0]
leading to our custom definition of struct Ipu3AwbCell.

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.

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. A full header update will be

In order to avoid depending on system headers that may be outdated compared
to the kernel version available at runtime, import the Linux kernel headers
related to the APIs that libcamera requires a recent version of. This allows
libcamera to use the latest kernel APIs even when compiled on older systems.
The library must of course test at runtime whether those APIs are available
and fallback to older APIs in order to support older kernels.
Import media.h for the recent media controller APIs. The file is extracted
verbatim from kernel v4.19.
