[PATCH] arm64: dts: qcom: sm6115: Add EUD dt node and dwc3 connector

From: Bhupesh Sharma
Date: Sat Dec 31 2022 - 08:20:04 EST


Add the Embedded USB Debugger(EUD) device tree node for
SM6115 / SM4250 SoC.

The node contains EUD base register region and EUD mode
manager register regions along with the interrupt entry.

Also add the typec connector node for EUD which is attached to
EUD node via port. EUD is also attached to DWC3 node via port.

- This patch is based on my earlier sm6115 usb related changes, which can
be seen here:
https://lore.kernel.org/linux-arm-msm/20221215094532.589291-1-bhupesh.sharma@xxxxxxxxxx/
- This patch is also dependent on my sm6115 eud dt-binding and driver changes
sent earlier, which can be seen here:
