Subject: [PATCH v2 0/2] arm64: dts: g12a/g12b: add the Ethernet PHY GPIO IRQs
Date: Sat, 15 Jun 2019 12:43:49 +0200 [thread overview]
Message-ID: <20190615104351.6844-1-martin.blumenstingl@googlemail.com> (raw)
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 my other series "Ethernet PHY reset GPIO updates for
Amlogic SoCs" from [0]
Changes since v1 at [1]:
- added Neil's Tested/Acked-by (thank you!)
- rebased on top of v3 of my other series
- updated cover-letter since the GPIO interrupt controller support
is now merged so it's not a dependency anymore
