Even if the Type-C controller supports PD, it is doable to disable PD capabilities with the current state machine in TCPM. Without enabling RX in low-level drivers and with skipping the power negotiation, the port is eligible to be a non-PD Type-C port. Use new flags whose values are populated from the device tree to decide the port PD capability. Adding "pd-disable" property in device tree indicates that the port does not support PD. If PD is not supported, the device tree property "typec-power-opmode" shall be added to specify the advertised Rp value if the port supports SRC role.

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.
