Subject: [PATCH 2/2] arm64: dts: qcom: x1e80100-t14s: Add external DP
support
The Lenovo Thinkpad T14s has only 2 USB Type-C ports, both of them
supporting external DP altmode. Between each QMP combo PHY and the
corresponding Type-C port, sits one Parade PS8830 retimer which handles
both orientation and SBU muxing. Add nodes for each retimer, fix the
graphs between connectors and the PHYs accordingly add the voltage
regulators needed by each retimer and then enable DP 0 and 1.
