Changes during conversion: - Drop the USB control module from child nodes, as it physically resides within the System Control Module address space, not the USB wrapper. - Allow standard phy@[0-9a-f]+$ child node names alongside the legacy usb-phy@[0-9a-f]+$. - Mark the legacy ti,hwmods property as deprecated. - Document required #address-cells, #size-cells, and ranges property missing from text binding.
