Hi Felipe,
AM335x SoC's used in boards like beagle bone has two instances of USB
modules (2.0) at the hardware level, each having a dedicated phy.
Currently in mainline, only one instance of USB is supported
(including a fix in your latest pull request). To support multi
instance, the biggest obstacle is lack of multi phy support for
usb phy's of same type.
Earlier Kishon was working on usb phy device tree support, later it was
seen that generic phy layer was preferred. And Kishon posted a couple of
versions on generic phy framework, latest being on 26th September 2012,
but I could not see follow up's on that series.
It seems Kishon is not now working on generic phy support. Let me know
your opinion/suggestions on supporting usb phy's of same type. We are
trying to get multi USB instance support in mainline for AM335x.
Regards
Afzal
