From dc5b201384644cf63e7523c2f9a39023435dd661 Mon Sep 17 00:00:00 2001 From: David Wu Date: Sat, 13 Jan 2018 13:53:54 +0800 Subject: [PATCH] rockchip: dts: rk3399-evb: Change the tx/rx delay value for transmission quality Give the mac controller the correct tx-delay and rx-delay value for the rgmii mode transmission. If they are not matched, there would be Ethernet packets lost, the net feature may not work.
