The RK3399 Puma SoM contains the internal Cypress CYUSB3304 USB hub, that shows instability due to improper reset pin configuration. Currently reset pin is modeled as a vcc5v0_host regulator, that might result in too short reset pulse duration. Starting with the v6.6, the Onboard USB hub driver (later renamed to Onboard USB dev) contains support for Cypress HX3 hub family. It can be now used to correctly model the RK3399 Puma SoM hardware.
