This SoC has 2 USB typeC and 2 typeA ports those are DWC3 DRD
controllers and among them, one single USB3.1 DRD combo phy and three
USB2.0 only phy controllers. This patchset adds and enables USB and
USB-PHY nodes in dts.
PMIC is not implemented yet, we rely on USB LDOs being enabled by the
bootloader and used dummy regulators for now.
To drive vbus for host mode, it needs GPIO pin to enable vbus regulator.
GPIO expander is present in the dts, we used it to enable the regulator
using GPIO.
USB ports are configured as OTG, and default mode is configured as
peripheral. It will be changed based on requirements.
