The MT6358 PMIC allows changing operating modes for the buck regulators, but not the LDOs. Existing device trees and the Linux implementation already utilize this through the standard regulator-allowed-modes property. The values currently used in existing device trees are simply raw numbers. The values in the Linux driver are matching numbers defined with macros denoting the two supported modes. Turns out these two modes are common across parts of the larger MT63xx PMIC family. The MT6397 regulator binding already has macros for the two modes, with matching numbers. Codify the supported values for regulator-allowed-modes for the MT6358 in the device tree binding: 0 and 1 are supported for buck regulators, and the property should not be present for LDO regulators. Users should use the dt-bindings/regulator/mediatek,mt6397-regulator.h header for the macros, instead of using raw numbers.

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 Restructured Text 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.
