<![CDATA[libgpiod support on the Onion Omega]]>Hello,
I was wondering if the Onion Omega Linux OS has libgpiod support and if someone has tested it already. I realize that sysfs gpio support already exists as does custom gpio libraries, but I was interested in playing around with the libgpiod implementation as well.

I have yet to test building gpio apps with libgpiod, but the basic libgpiod bash commands such as gpioinfo, gpiodetect, gpioset and gpioget all work on gpio pins 15,16 & 17 (attached to the RGB LED on the expansion dock). I will be experimenting further with this in the coming days.

So each OpenWrt 18.06 based Omega2 firmware from v0.3.2 b217 supports them too.
