I am using imx6p solo and I'd like to add OPT3001 Digital Ambient Light Sensor to my linux kernel. However, kernel configuration options (Symbol: OPT3001 [=y]) is missing in the kernel that we are using. here is "uname -a"

Linux acompany 4.1.15-1.2.0+g7d6134 #1 SMP PREEMPT Wed Oct 18 15:25:22 CEST 2017 armv7l GNU/Linux

How I can upgrade kernel in yocto to support it? if not possible why? and how I can port  "drivers/iio/light/opt3001.c" to our kernel?
