The MediaTek MT6366 PMIC is similar to the MT6358 PMIC. It is designed to be paired with the MediaTek MT8186 SoC. It has 9 buck regulators and 29 LDO regulators, not counting ones that feed internally and basically have no controls. The regulators are named after their intended usage for the SoC and system design, thus not named generically as ldoX or dcdcX, but as vcn33 or vgpu. The differences compared to the MT6358 are minimal: - Regulators removed: VCAMA1, VCAMA2, VCAMD, VCAMIO, VLDO28 - Regulators added: VM18, VMDDR, VSRAM_CORE Both PMIC models contain a chip ID register at the same address that can be used to differentiate the actual model. Thus, even though the MT6366 is not fully backward compatible with the MT6358, it still falls back on the MT6358 compatible string. It is up to the implementation to use the chip ID register as a probing mechanism. Update the MT6358 regulator binding and add entries for all the MT6366's regulators and their supplies. The regulator node names follow a cleaned up style without type prefixes and with underscores replaced with hyphens.

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.
