On Pixel 6 (and Pro), a max77759 companion PMIC for USB Type-C applications is used, which contains four functional blocks (at distinct I2C addresses): * top (including GPIO) * charger * fuel gauge * TCPCi While in the same package, TCPCi and Fuel Gauge have separate I2C addresses, interrupt lines and interrupt status registers and can be treated independently. The TCPCi is required to detect and handle connector orientation in Pixel's USB PHY driver, and to configure the USB controller's role (host vs device). This change adds the TCPCi part as it can be independent and doesn't need a top-level MFD.

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.
