dt-bindings: phy: qcom,sc8280xp-qmp-usb43dp-phy: Document lanes mapping when not using in USB-C complex
The QMP USB3/DP Combo PHY hosts an USB3 phy and a DP PHY on top
of a combo glue to route either lanes to the 4 shared physical lanes.
The routing of the lanes can be:
- 2 DP + 2 USB3
- 4 DP
- 2 USB3
The layout of the lanes was designed to be mapped and swapped
related to the USB-C Power Delivery negociation, so it supports
a finite set of mappings inherited by the USB-C Altmode layouts.
Nevertheless those QMP Comby PHY can be used to drive a DisplayPort
connector, DP->HDMI bridge, USB3 A Connector, etc... without
an USB-C connector and no PD events.
Document the data-lanes on numbered port@0 out endpoints,
allowing us to document the lanes mapping to DisplayPort
and/or USB3 connectors/peripherals.
