From 40db7a9dec92d3e263bd0933b972865061419e2e Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Thu, 28 Dec 2017 19:34:47 +0100 Subject: [PATCH] sunxi: Orange Pi R1: Fix USB Ethernet and activate SPI The USB Ethernet is not working with the patches proposed for upstream, fix this and activate the SPI node as this board always has a SPI flash. Both patches are also targeted for upstream kernel 4.16 and 4.17.
