[ 1.035759] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver [ 1.042319] usbcore: registered new interface driver usb-storage [ 1.073619] e0002000.ps7-usb supply vbus not found, using dummy regulator [ 1.103560] Registering platform device 'ci_hdrc.0'.

problem 1: vbus not found
reason?
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>;
view-port = <0x170>;
} ;
- order in device tree does not matter
