Hi Hans,

The following is the latest test log, which does not report a failure, but
also reports "Unknown Function".

I make the following settings in the stf-isp.c file:
v4l2_subdev.entity.function = MEDIA_ENT_F_PROC_VIDEO_ISP;

# 
# v4l2-compliance -m /dev/media0
v4l2-compliance 1.25.0, 64 bits, 64-bit time_t
