Subject: [PATCH 0/2] arm64: dts: g12a/g12b: add the Ethernet PHY GPIO IRQs

Avoid polling of the PHY status by passing the Ethernet PHY's GPIO
interrupt line to the PHY node.

I tested this successfully on my X96 Max, but I don't have an Odroid-N2
to test it there. The reset and interrupt GPIO part of the schematics
seems to be identical for both boards (and probably other "reference
design" based boards as well).

This depends on two of my other series:
1. "irqchip/meson-gpio: Add support for Meson-G12A SoC" from [0]
2. "Ethernet PHY reset GPIO updates for Amlogic SoCs" from [1]
