[PATCH 0/2] pinctrl: Enable support for external GPIO interrupts

From: Carlo Caione <carlo at endlessm.com>
In Meson SoCs we have 8 independent GPIO interrupts that can be programmed to
use any of the GPIOs in the chip as interrupt source.
These GPIOs are managed by GIC but they can be conditioned (and enabled) by
some registers external to the GIC.
GPIOs |--[mux1 or mux2]--[polarity]--[filter]--[edge_select]--> GIC
The original work has been done by Beniamino. I cleaned it up, fixed a couple
of bugs, added support for Meson8b and the fix for the .to_irq hook.
