From bb0516f4d03ffe9bcc06f840e477ea665af94e9d Mon Sep 17 00:00:00 2001 From: Jernej Skrabec Date: Sun, 25 Aug 2019 14:40:10 +0200 Subject: [PATCH] arm64: dts: allwinner: a64: pine64-plus: Add PHY regulator delay Depending on kernel and bootloader configuration, it's possible that Realtek ethernet PHY isn't powered on properly. It needs some time before it can be used. Fix that by adding 100ms ramp delay to regulator responsible for powering PHY.
