Subject: [PATCH 2/2] arm64: dts: meson: g12a: x96-max: add the Ethernet PHY interrupt line
Date: Mon, 10 Jun 2019 18:45:31 +0200
Message-ID: <20190610164531.8303-3-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190610164531.8303-1-martin.blumenstingl@googlemail.com>

X96 Max has the PHY reset and interrupt lines are identical to the
Odroid-N2:
- GPIOZ_14 is the interrupt on X96 Max
- GPIOZ_15 is the reset line on X96 Max

Add GPIOZ_14 as PHY interrupt line on the X96 Max so we don't have to
poll for the PHY status.

Suggested-by: Neil Armstrong <narmstrong@baylibre.com>
