ARM: dts: sun8i: r40: bananapi-m2-berry: Fix dcdc1 regulator
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") Signed-off-by: Pablo Greco <pgreco@centosproject.org> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Link: https://lore.kernel.org/r/1604326755-39742-1-git-send-email-pgreco@centosproject.org
