The HX3 is a family of USB3.0 hub controllers that comes in different variants: CYUSB330x/CYUSB331x/CYUSB332x/CYUSB230x. To support this hub, controlling of reset pin and two power supplies is required. The reset time is set to 10ms, based on the datasheet [1]. Power-on delay time is not required, so it is set to 0. The compatible strings added to of_match table are compliant with usb/cypress,hx3.yaml bindings.
