Due to an error while handling vbus_pin_active_low in ohci-at91 driver,
the specification of this property was not good in devices/board files.

The DT information are filled in a pdata structure and then passed on
to the usual check code of the probe function. Thus we do not need to
redo the gpio checking and irq configuration in the DT-related code.
On the other hand, we setup GPIO direction in driver for vbus and
overcurrent. It will be useful when moving to pinctrl subsystem.

Did you run this patch through scripts/checkpatch.pl? I have the
feeling that it might complain about some of the changes.

Yes, definitively.
I can modify the patch to comply with error issued by checkpatch.pl: several are
due to a bad replacement of previous code with my regular expression but others
where existing before my modifications.
So what do you think about:
- addressing all style errors in this patch (to prevent carrying them)
- merging this one and the following patch:
"[PATCH v2 07/13] USB: ohci-at91: coding style modifications with one-line ifs
- posting a v3 of this patch only if you agree on this...
Best regards,

Sure, go ahead. Aside from this minor issue I didn't notice anything
objectionable in the patch series.

Change number of ports to 3 for newer SoCs. Modify pdata structure
and ohci-at91 code that was dealing with ports information and check
of port indexes.
Several coding style errors have been addresses as the patch was touching
affected lines of code and was producing errors while run through
checkpatch.pl.

v3: - address all style errors in this patch (to prevent carrying them)
- merge following patch about one-line ifs
v2: - use of AT91_MAX_USBH_PORTS instead of ARRAY_SIZE()
- modify wIndex ohci_at91_hub_control() for simpler code

address on a non-ambiguous device node isn't necessary anyway, so this
patch is still a reasonable thing to do.

It's actually a 'feature' of the way we're including skeleton.dtsi.
skeleton.dtsi has already set the node name, so if the next file
doesn't use exactly the same node name then the .dtb ends up with two
memory nodes, which is really bad.
It real problem is the dtc tooling.

Hi Greg,
I would like to send this "fixes" patch series via arm-soc. Is it
possible for you to have a look at patches that will modify ohci-at91
(and the tiny ehci-atmel one) and give me your "Acked-by" so that I can
ask Arnd and Olof to queue this material for 3.4-rc?
Here is the thread in linux-usb mainling-list:
http://www.spinics.net/lists/linux-usb/msg60798.html
Thanks for your help, best regards,
