[PATCH 1/3] dt-bindings: usb: typec: Add Cypress CYPD6129 UCSI controller compatible

[Akash Kumar]

Document the "cypress,cypd6129" compatible string for the Cypress/Infineon
EZ-PD CCGx UCSI controller.

The CYPD6129 is compatible with the existing CCGx binding, so allow it as a
valid compatible and permit the existing "cypress,cypd4226" fallback where
appropriate.
