We want to integrate a light sensor driver with Ubuntu's kernel. Please advise how can we do it.

The light sensor code given in opt3001.c here.

It seems this is the mainline upstream kernel, so please have a look at MainlineBuilds, you can probably find the kernel suiting your needs here.

On ubuntu 16.04 , the default kernel (4.4) is too old for compiling this driver. But you can install a more recent kernel HWE using this command : sudo apt-get install --install-recommends linux-generic-hwe-16.04.

Manual compiling, tested on 16.04 with kernel 4.10.0-35-generic

mkdir opt3001 && cd opt3001
wget https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/drivers/iio/light/opt3001.c
echo 'obj-$(CONFIG_OPT3001)     += opt3001.o' > Makefile
make -C /lib/modules/$(uname -r)/build M=$(pwd) modules

Some packages may be necessary (build-essential, linux-headers-$(uname -r), ...).

And you may have a look at this answer if you have troubles with secure boot (insmod: ERROR: could not insert module opt3001.ko: Required key not available).
