I'll have to read the usb/ulpi specification more carefuly - if anyone with greater knowledge is interested - please, don't hasitate to join the discussion :-)

this seems to continue being fun...
ISP1707 have all ULPI registers in range 0x0 - 0x1B,
plus PWR_CTRL registers 0x3D - 0x3F.
Most interesting - OTG_CTRL 0xA - 0xC and
Function Control 0x4 - 0x6.
