==problem 1: vbus not found==
===reason?===
the problem is not critical

==problem 2: unable to init phy: -110==
===reason?===
* corrected the device tree record (s/viewport/view-port/):
usb_phy0: phy0{
compatible = "ulpi-phy";
#phy-cells = <0>;
reg = <0xe0002000 0x1000>;
<b>view-port</b> = <0x170>;
} ;
* order in device tree does not matter
