I have a customized board running OTG/host and USB2/host (USB1 not connected)
Both ports are connected to a ISP1504 ULPI
a) I need a rs-gpio to reset in addition to the cs-gpio the ISP1504 (done)
b) Implement UPLI viewport (IORESOURCE_MEM) and logic to set the external power 
supply.
The code (b) was rejected and needs rework.

I will fix the problem with (b) and resend my patches.
