This patch implements USB mode setting via a sysfs interface in cros_ec_typec driver. User-space applications can now change the current USB mode by writing to "usb_mode" sysfs entry, replacing the previous ioctl-based method. The embedded controller (EC) currently supports only entering USB4 mode and exiting all modes (including altmodes). Both of these operations trigger Data Reset Message, even if no USB Mode is active. Additionally, the patch exposes the USB modes supported by the port via "usb_capability" sysfs attribute.

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.
