This adds the USB nodes to RK3528 and therefore needs both the dwc3
compatible [0], as well as the phy support [1] to be merged first.
changes in v3:
- moved snps,dis_u2_susphy_quirk to the soc dtsi
- describe both usb2- and usb3-phy in the host0
if boards only wire up half of the functionality, they get
to override the phy-properties - as they already do
- add vbus-supply to armsom sige1
changes in v2:
- split off from original series [2], that added all 3 parts

Rockchip RK3528 has one USB 3.0 DWC3 controller and oneUSB 2.0 EHCI/OHCI
controller and uses an Innosilicon-USB2PHY for USB 2.0. The DWC3
controller additionally uses the Naneng Combo PHY for USB3.
Add device tree nodes to describe these USB controllers along with the
USB 2.0 PHYs.

The semicolon is missing at the end.
It should be located in the otg node:
&usb2phy0_otg {
phy-supply = <&vcc5v0_usb_otg>;
status = "okay";
};
Thanks,
