Hi Krzysztof, thank you for taking a look at this series. Clearly it
needs some more work. I’ll follow up with a v2 addressing your
comments.

TCPCs and PDCs are different components which can be used for power
delivery messaging on USB-C ports. On ChromeOS devices, they are
mutually exclusive. This line is just saying which driver should be
chosen based on the USB-C port hardware. But, I see that type of
information isn’t really relevant for the device tree documentation.

Thanks,
Jameson
