From 1a4e6203f0c870aab89eb6727759374fddb071aa Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Fri, 15 Mar 2019 01:05:30 +0000 Subject: [PATCH] arm64: dts: rockchip: Add nanopi4 ethernet phy The nanopi4 boards have the INTB pin of the RTL8211E phy wired up, so we can make use of that and avoid having to poll for line status changes. Apparently RTL8211E only requires 30ms of post-reset delay, so we may as well save a little bit of time there as well.
