ChromeOS devices can have one optional dedicated port. The Dedicated port is unique and similar to the USB PD ports except that it doesn't support as many properties. The presence of a dedicated port is determined from whether the EC's charger port count is equal to 'number of USB PD port' + 1. The dedicated port ID is always the last valid port ID. This commit keeps compatibility with Embedded Controllers that do not support the new EC_CMD_CHARGE_PORT_COUNT command by setting the number of charger port to be equal to the number of USB PD port when this command fails.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
