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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
