There was a discussion [0] recently about what license(s) should be
used for Device Tree source files. It seems that we have been using
GPLv2-only just because is the Linux kernel license but unlike other
source files, the DTS could be used verbatim in other operating
systems / bootloaders so we have to better think the implications of
the licensing.
Of course this shouldn't hold your patch, I'm just mentioning so you
can keep an eye in case an agreement is made while you are pushing
this.

You are already including <dt-bindings/gpio/gpio.h> so please use the
GPIO constants instead of magic numbers (e.g: GPIO_ACTIVE_HIGH in this
case). Same for others gpios properties.
