This patchset is the userspace support for the CSC API RFC v4:
https://patchwork.kernel.org/project/linux-media/list/?series=298891
Patches Summary:
================
patch 1 - allows userspace to set the quantization and {ycbcr/hsv}_enc
fields in the command 'v4l2-ctl --set-fmt-video ..'
it also adds the new enumeration flags to the compliance tests.
patch 2 - adds the new enumeration flags V4L2_FMT_FLAG_CSC* to
the function that prints the string description of the flags.
The array fmtdesc_def is replaced by a macro FMTDESC_DEF(enc_type)
since the flags V4L2_FMT_FLAG_CSC_YCBCR_ENC,V4L2_FMT_FLAG_CSC_HSV_ENC,
have identical value and the string should change according to whether
the pixelformat is HSV or not.
patches 4, 3 - are similar to patches 1, 2 but for subdevices.
So patch 3 adds support for the CSC API for subdevices
and patch 4 adds the new enumeration flags V4L2_SUBDEV_MBUS_CODE_CSC*
to the framework that prints the related string description
Testing:
=======
I added a python script to run all possible combinations of CSC
settings on vivid:
https://gitlab.collabora.com/dafna/v4l-utils/-/blob/csc-rfc-v4-jun-6-mittag/contrib/test/vivid_test_csc.py
The commands to run the script:
git clone --single-branch --branch csc-rfc-v4-jun-6-mittag https://gitlab.collabora.com/dafna/v4l-utils.git
cd v4l-utils/contrib/test/
modprobe vivid
python3 vivid_test_csc.py
Also added test for rkisp1:
https://gitlab.collabora.com/dafna/v4l-utils/-/blob/csc-rfc-v4-jun-6-mittag/contrib/test/rkisp1-unit-tests.sh
To run the test:
git clone --single-branch --branch csc-rfc-v4-jun-6-mittag https://gitlab.collabora.com/dafna/v4l-utils.git
cd v4l-utils/contrib/test/
./rkisp1-unit-tests.sh

With the CSC API, capture drivers can allow userspace to request
to set the quantization or the ycbcr_enc/hsv_enc fields of the
pixelformat. This patch adds supports for this feature.
when calling 'v4l2-ctl --set-fmt-video' on capture devices
userspace can ask to change the quantization or the ycbcr/hsv_enc
of the format if the driver supports it.

Replace the array fmtdesc_def with a macro 'FMTDESC_DEF'
The macro is used to to create two arrays 'fmtdesc_def_ycbcr',
'fmtdesc_def_hsv' that map the format flags to strings.
The function 'fmtdesc2s' is changed to get a parameter 'is_hsv'
that decides which array to use.
The new CSC flags V4L2_FMT_FLAG_CSC* are added to the arries.

The CSC API allows userspace to configure the quantization and
(ycbcr/hsv)_enc fields when setting the formats, so those fields
are not read only in userspace. This patch adds support for
this API in subevices.

Add a new function mbus2s to that prints a descriptive
string of the supported flags of the the v4l2_subdev_mbus_code_enum
Use this function in the print_mbus_code function.
Also add a macro MBUS_DEF(enc_type) to create the two
arries 'mbus_hsv_def' and mbus_ycbcr_def' that maps flags to
string according to the enc_type (ycbcr/hsv)
