[libcamera-devel] [PATCH v3 0/8] v4l2_(sub)dev: improvements and tests

[Jacopo Mondi]

Hello, another round for this mixed improvements and tests for v4l2 subdevice
and v4l2 device.

Compared to v2, the format enumeration has changed to handle subdevices that do
not implement the IOCTL and return ENOTTY when called.

Other minor changes: I've added a patch to update the crop/scale rectangle and
one that makes V4L2Subdevice inherit from Loggable to add a prefix tag to
the log message.

I have not updated the kernel headers yet, as META_OUTPUT will be added in
v5.0 and not v4.20 as I initially though.

Thanks
