From 729e1ffcf47e5e035a9a504e81e8d25403919993 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Sat, 3 Nov 2018 20:32:38 +0800 Subject: [PATCH] arm64: allwinner: h6: add support for the Ethernet on Pine H64 The Pine H64 board has an Ethernet port, which is connected to a RTL8211E PHY, then the PHY is connected to the MAC on H6 SoC. Add support for the Ethernet port. The PHY needs some time to start up, and the time is modelled as enable ramp delay of the regulator.
