From 7c798a11d499dbf5c1c12eedec6bd7299b906b2b Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Wed, 20 Mar 2019 15:32:41 +0800 Subject: [PATCH] poplar: enable Ethernet driver support The 'phy' reset of gmac device in kernel device tree is not generic enough for u-boot to use, so we need to overwrite the 'resets' property as needed. With this device tree fixup and poplar_defconfig changes, Ethernet starts working on Poplar board.
