This SoC has 2 USB typeC and 2 typeA ports those are DWC3 DRD controllers and amoung them, one is USB3.1 DRD combo phy and three USB2.0 phy controllers. This patchset adds and enables USB and USB-PHY nodes in dts. PMIC driver is not implmented 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 vbus regulator using GPIO. USB ports are configured as OTG, and default mode is configured as peripheral. These configurations might be changed based on requirements. This patchset has dependancy on schema and driver implementation[1] and role switch control from userspace[2] patches.

I closed my tree few days ago, so next cycle, but please resend, because this is three months old now. I dropped it from my queue long time ago. Best regards, Krzysztof
