Sinovoip has released other variants of Bananapi-R4 board.
The known changes affecting only the LAN SFP+ slot which is replaced
by a 2.5G phy with optional PoE.
Just move the common parts to a new dtsi and keep differences (only
i2c for lan-sfp) in dts.

Bananapi R4 Board contains a MT6682A pmic which is compatible to rt5190a.
Add its node to the i2 controller.
The BananaPi R4 board has a MediaTek MT6682A PMIC, a rebrand of the
Richtek RT5190A chip, connected to the I2C0 bus.
Add the relevant node and, while at it, also configure the regulators
from this PMIC that are used on this board.
Only Buck2/Buck3 voltage can be controlled by software.
BUCK4 input is 5V from BUCK1 output, and the resistor (mapped to RP30/RP31
on BPI-R4) configures BUCK4 output to 1.8V.
LDO input is 3.3V from 3.3VD, and the resistor (mapped to RP38/RP40 on
BPI-R4) configures LDO output to 1.8V.

Enable the I2C0, I2C2 controllers found on the BananaPi R4 board.
Both controllers are not accessible from user and having fixed spare
devices. I2C0 have a pmic connected, I2C2 is used with I2C-multiplexer
for e.g. SFP cages.
The missing I2C1 is connected to GPIO header which can have either GPIO
mode or I2C mode.

Add regulator nodes used for mmc to Bananapi R4 board.
This board has 1 MMC controller used for SDMMC and eMMC where only one can
be used at one time, selected by hardware switches. SD uses 3v3 for both
supplies and emmc uses both regulators.
So defining both regulators in board dts and referencing them in the dt
overlay.

MT7988A (AKA MediaTek Filogic 880) is a quad-core ARM Cortex-A73
platform designed for Wi-Fi 7 devices (there is no wireless on SoC
though). The first public MT7988A device is Banana Pi BPI-R4.
Many SoC parts remain to be added (they need their own bindings or
depend on missing clocks). Those present block however are correct and
having base .dtsi will help testing & working on missing stuff.
