Subject: [PATCH] ARM: dts: sun8i: r40: bananapi-m2-berry: Fix dcdc1 regulator
Date: Mon, 2 Nov 2020 11:19:14 -0300 [thread overview]
Message-ID: <1604326755-39742-1-git-send-email-pgreco@centosproject.org> (raw)
DCDC1 regulator powers many different subsystems. While some of them can
work at 3.0 V, some of them can not. For example, VCC-HDMI can only work
between 3.24 V and 3.36 V. According to OS images provided by the board
manufacturer this regulator should be set to 3.3 V.
Set DCDC1 and DCDC1SW to 3.3 V in order to fix this.
Fixes: 23edc168bd98 ("ARM: dts: sun8i: Add board dts file for Banana Pi M2 Berry")
Fixes: 27e81e1970a8 ("ARM: dts: sun8i: v40: bananapi-m2-berry: Enable GMAC ethernet controller")
