Subject: Question on OTG transceivers
Date: Wed, 17 Mar 2010 16:35:02 -0500 [thread overview]
Message-ID: <4BA14B06.8050202@billgatliff.com> (raw)
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.
