Dear Maintainer,

please set CONFIG_INTEL_SKL_INT3472=m to build the intel-skl-int3472 module.

This module is necessary to use some cameras built into Intel Skylake laptops.

Dear maintainer,

since kernel 6.4.

CONFIG_VIDEO_V4L2_SUBDEV_API=y needs to be set aswell.

It was previously enabled until kernel 6.3.


CONFIG_INTEL_SKL_INT3472=m and
CONFIG_VIDEO_V4L2_SUBDEV_API=y

are needed to compile ipu6-drivers-dkms for the new Intel Computervision 
webcams present in major manufacturer's new designs, for example 
Lenovo's X1 Carbon gen10+ or X1 Yoga Gen7+.

Thank you

Martin

This driver should select VIDEO_V4L2_SUBDEV_API, right?

currently the dkms from ipu6-drivers just fails to compile when 
CONFIG_VIDEO_V4L2_SUBDEV_API is not set. So if I enable some other not 
related media driver that selects CONFIG_VIDEO_V4L2_SUBDEV_API=y I can 
build ipu6-drivers.

I simply noticed that
config-6.3.0-1-amd64 and
config-6.3.0-2-amd64
have CONFIG_VIDEO_V4L2_SUBDEV_API=y while config-6.4.0-1-amd64 has not.

I do not know the reasoning for the removal of that config.

At this point I am just grateful I can use the camera in my device at all :)


Cheers

Martin

If this driver requires this API then it should select VIDEO_V4L2_SUBDEV_API.
Could you eventually send a bug report upstream?

CONFIG_VIDEO_V4L2_SUBDEV_API was available in Linux 6.3 thanks to the 
CONFIG_VIDEO_NOON010PC30 option. However that camera sensor driver has been
dropped in Linux 6.4 and none of the camera sensor drivers enabled in Debian
select CONFIG_VIDEO_V4L2_SUBDEV_API.

Understandable ;)
