[OpenWrt-Devel] [PATCH 8/8] staging: mt7621-dts: add interrupt device tree nodes for the gpio controller

[Rosen Penev]

From: Sergio Paracuellos <sergio.paracuellos at gmail.com>

The GPIO controller of mt7621 can receive interrupts on any
of the GPIOs, either edge or level. It then interrupts the CPU using
GIC INT12. Update device tree accordly.
