From 32f6c700a5eee59ab723a25f8a363b95559d71bf Mon Sep 17 00:00:00 2001 From: Corentin Labbe Date: Mon, 9 Jul 2018 19:51:54 +0000 Subject: [PATCH] ARM: dts: sun8i: a83t: bananapi-m3: increase vcc-pd voltage to 3.3V [ Upstream commit 5f8208f557065163f9a8089ea2ea7888f9d96922 ] Since commit d7c5f6863550 ("ARM: dts: sun8i: a83t: bananapi-m3: Add AXP813 regulator nodes") my BPIM3 no longer works at gigabit speed. With the default setting, dldo3 is regulated at 2.9v which seems sufficient for the PHY but the aforementioned commit drops it to 2.5V which is insufficient. Note that this behaviour is random for all BPIM3. Some work with 2.5V, but some don't. Finnaly, someone from Bananapi confirmed that this regulator must be set to 3.3V.
