From dc082d188f3d3803206282c81ac9c0bf56674e2c Mon Sep 17 00:00:00 2001 From: Antony Antony Date: Thu, 24 Aug 2017 18:50:37 +0200 Subject: [PATCH] Add kernel DT support for Nano Pi Neo Plus 2 (nanopineoplus2) This DT is based on OrangePi PC 2 sun50i-h5-orangepi-pc2 kernel 4.13-rc6 Modify DT to support Gigabit Ethernet using dwmac-sun8i driver. https://www.spinics.net/lists/arm-kernel/msg586106.html Then compared the schematics of "Nano Pi Neo2" and "Nano Pi Neo Plus 2" and the change looks good for Nano Pi Neo Plus2 too.
