[v1,00/11] Used onboard HUB to reset and add power to hub

Message

Amlogic board use gpio-hog to reset the USB hub.
so using onboard hub we could reset the USB hub and
also enable power to the USB hub.

On Odroid C1, it seem this feature is not working as expected
so just included the patch for testing. Maybe we can drop this.

$ lsusb -t
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc2/1p, 480M

On Odroid C2, C4, N2 is seem to work as expected.

$ lsusb -t
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/2p, 480M
    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M

Any inputs?

Thanks
