[PATCH] ARM: dts: sun8i: r40: bananapi-m2-berry: Fix dcdc1 regulator

[Pablo Greco]

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.

[PATCH] ARM: dts: sun7i: bananapi: Enable RGMII RX/TX delay on Ethernet PHY

[Pablo Greco]

The Ethernet PHY on the Bananapi M1 has the RX and TX delays enabled on
the PHY, using pull-ups on the RXDLY and TXDLY pins.

Fix the phy-mode description to correct reflect this so that the
implementation doesn't reconfigure the delays incorrectly. This
happened with commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e
rx/tx delay config").
