Hi!
For power management experiments, I tried
CONFIG_USB_OHCI_HCD=y
CONFIG_USB_OHCI_HCD_OMAP3=m
CONFIG_USB_OHCI_HCD_PLATFORM=y
and could not find resulting .ko.
Help text says:
CONFIG_USB_OHCI_HCD_OMAP3:
This option is deprecated now and the driver was removed, use
USB_OHCI_HCD_PLATFORM instead.
Enables support for the on-chip OHCI controller on
OMAP3 and later chips.
Which may partly explain it. But if the option no longer does
anything, why keep it? Certainly second part is confusing if option is
NOP...

Yeah it's ohci-platform now, I think we decided to keep the old one
around to avoid breaking people's .config files for booting rather
than silently fail.

Ok, what about this? (Should I do the same for the other drivers?)
Or at least put (DEPRECATED) as other drivers do?
Situation is quite confusing if you already have PLATFORM=y. OMAP=m
can be selected, but nothing happens.

Sure works for me, let's see what linux-usb people think.
