Re: [PATCH v2 1/3] dt-bindings: chrome: Add Cros EC UCSI driver

What's PDC? What's UCSI?

PDCs are "Power Delivery Controllers". It refers to an IC which
manages PD communication for a USB-C port. UCSI stands for "USB Type-C
Connector System Software Interface". It is a specification maintained
by the USB-IF which defines a standardized interface for communicating
with PDCs. I'll update the description in the v3 series to provide the
full name for both of these terms.

This is the exact same binding as google,cros-ec-typec.yaml. Why are you
duplicating the whole thing rather than just adding a new compatible
string?

I separated these bindings because they are associated with separate
mutually exclusive drivers. But, I'm fine with adding this as a
compatibility string in google,cros-ec-typec.yaml and will make that
change in the v3 series.
