Subject: [PATCH v4] arm64: dts: qcom: lemans-evk: Add OTG support for primary USB controller
Enable OTG support for primary USB controller on EVK Platform. Add
HD3SS3220 Type-C port controller present between Type-C port and SoC
that provides role switch notifications to controller.
Signed-off-by: Krishna Kurapati <krishna.kurapati@....qualcomm.com>
---
Changes in v4:
- Moved remote endpoints to SoC file.
- Renamed vbus regulator name.
- Moved usb-role-swich property to SoC file.
Changes in v3:
- Moved "usb-role-switch" to lemans dtsi file
- Moved vbus supply to connector node
