USB 3.0 support for Rockchip RK3328

[Denis Polygalov]

After application of this patch:
https://patchwork.kernel.org/patch/10853381/
and recompiling kernel I got this in dmesg:

# dmesg | egrep 'usb|dwc|USB'
dwc0: <Rockchip Gigabit Ethernet Controller> mem 0xff540000-0xff54ffff 
irq 43 on ofwbus0
miibus0: <MII bus> on dwc0
dwc0: Ethernet address: 82:d6:05:ce:da:87

usbus0 on dwcotg0
usbus1 on ohci0

uhub1 on usbus0
uhub1: <DWCOTG OTG Root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus0
Root mount waiting for: usbus1 usbus0
dwc0: link state changed to DOWN
dwc0: link state changed to UP

but no response to connection of any USB device.
Also I noticed that 'gpioctl -f /dev/gpioc4 26 1'
make sense only for ROCKPro64 which is not what I have:

  # ls /dev/gp*
/dev/gpioc0     /dev/gpioc1     /dev/gpioc2     /dev/gpioc3

Is there some similar magic command to turn on USB parts on ROCK64?

Regards,
Denis.
