Question on OTG transceivers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Guys:


I have a Beagleboard-like unit here that uses two SMSC USB3320C-EZK
PHYs: one for EHCI (usb1), the other for OTG (usb0).

Two questions.  First, the code in drivers/usb/otg/ulpi.c looks like it
might be what I need (my attempts so far with the "nop" transceiver have
ended in failure).  Am I right?

Second, it looks like otg_set_transceiver() assumes there is only one
transceiver in the system.  On a device like the OMAP3530 with multiple
ports, this seems like an odd assumption--- and one that clearly isn't
accurate for my platform.  Or am I paying attention to the wrong stuff?

Can anyone help navigate me through the trees in this forest?  :)


Thanks!


b.g.
