I will add gpio-line-name for the two accessible GPIOs on X16 that are
not mapped to specific functions. I will also add the heartbeat LED that
is located on the SoM. Regarding the two switches on the phyBOARD, they
reset the CPU and the board so I am not sure that they can have an entry
in the device tree.

Thanks,

Mathieu
