Cosmo Chou f9bd09ef2c usb: typec: tcpm: Use configured PD revision for negotiation
Initialize negotiated_rev and negotiated_rev_prime based on the port's
configured PD revision (rev_major) rather than always defaulting to
PD_MAX_REV. This ensures ports start PD communication using their
appropriate revision level.

This allows proper communication with devices that require specific
PD revision levels, especially for the hardware designed for PD 1.0
or 2.0 specifications.

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.
