[PATCH 9/9] arm64: dts: qcom: ipq9574: Flatten usb controller node

[George Moussalem via B4 Relay]

From: George Moussalem <george.moussalem@xxxxxxxxxxx>

Flatten usb controller nodes and update to using latest bindings and
flattened driver approach.

Add property to the USB node to select UTMI as reference clock for the
DWC3 core to calculate the right values for the period and frame length
adjustment.
