Linux kernel source tree
e03f6fef5e
Add negotiated revision and tx/rx message ids to tcpm_port specific to SOP'. tx_sop_type is added to the tcpm_port to determine whether the current constructed message will be sent over SOP or SOP' if not sent immediately. tcpm_pd_rx_handler updates the received message ids. SOP* messages are not processed afterwards. The handler also calls tcpm_can_communicate_sop_prime to determine if a SOP' message is directed towards the port, and drops SOP' messages it should not respond to. tcpm_can_communicate_sop_prime is added as a helper to determine whether the port is capable of communicating over SOP' at a given moment. Being the Vconn source is a requirement in Power Delivery 3.0 but only a recommendation in Power Delviery 2.0. Because the port should ensure that the cable is powered before communication, always enforce the port is the Vconn source regardless of revision.

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.
