Subject: [PATCH 3/3] arm: dts: sun6i: a31s: fix: bpi-m2: add missing regulators
Date: Fri, 9 Feb 2018 18:52:36 +0100 [thread overview]
Message-ID: <20180209175236.21215-4-embed3d@gmail.com> (raw)
In-Reply-To: <20180209175236.21215-1-embed3d-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
This patch fixes a bootproblem with the Bananapi M2 board. Since there
are some regulators missing we add them right now. Those values come
from the schematic, below you can find a small overview:
* reg_aldo1: 3,3V, powers the wifi
* reg_aldo2: 2,5V, powers the IO of the RTL8211E
* reg_aldo3: 3,3V, powers the audio
* reg_dldo1: 3,0V, powers the RTL8211E
* reg_dldo2: 2,8V, powers the analog part of the csi
* reg_dldo3: 3,3V, powers misc
* reg_eldo1: 1,8V, powers the csi
* reg_ldo_io1:1,8V, powers the gpio
* reg_dc5ldo: needs to be always on
