A few patches ago, I removed the reset_resume callback, changing it to resume instead. Now that the usb-serial core supports reset_resume, put this driver callback back as well, so it should work identically to how it was originally. Now if this function really is doing what it should be doing, well, that's a different story, but we are at least doing the identical thing that we were before...

The callback is now hooked up for any USB to serial driver that wants it. We only register the callback if any of the usb-serial structures want it, this keeps the USB core happy.

This patch (as1556) works around a bug in the Philips ISP1562 EHCI controller. Although the controller claims to support frame-list lengths smaller than the default of 1024 for its periodic schedule, in fact smaller values don't work. A new quirk flag is added to indicate when the bug is present, and if it is then the schedule size is left at the default value.

This patch (as1555) improves the code ehci-hcd uses while checking the periodic schedule for isochronous transfers to full-speed devices. In addition to making sure that a new transfer does not violate the restrictions on the high-speed schedule, it also has to check the restrictions on the full-speed part of the bus, i.e., the part beyond the Transaction Translator (TT). It does this by calling tt_available() (or tt_no_collision() if CONFIG_USB_EHCI_TT_NEWSCHED isn't enabled). However it calls that routine on each pass through a loop over the frames being modified, which is an unnecessary expense because tt_available() (or tt_no_collision) already does its own loop over frames. It is sufficient to do the check just once, before starting the loop. In addition, the function calls incorrectly converted the transfer's period from microframes to frames by doing a left shift instead of a right shift. The patch fixes this while moving the calls.

Basically, ->vbus_session() calls should be served when VBUS session starts and ends (it's not whenever transciever drivers detect VBUS _changes_). Otherwise, if UDC gadget drivers don't want for some reason ->vbus_session() calls with the same "is_active" value, either OTG or UDC drivers need to have some protection handlings. Also, on platforms using this 'gpio_vbus' driver, the driver is only allowed to check whether VBUS is applied. There is no kernel-standard way prepared for UDC gadget drivers to do that. With this in mind, gpio_vbus should try to prevent unnecessary consecutive vbus_session calls being served with the same "in_active" value.

In commit c2344f13 (USB: gpio_vbus: add delayed vbus_session calls, 2009-01-24), usb_gadget_vbus_connect() and ...disconnect() were extracted from the interrupt handler, so to allow vbus_session handlers to deal with msleep() calls. This patch takes the approach one step further. USB2.0 specification (7.1.7.3 Connect and Disconnect Signaling) says that the USB system software (shall) provide a debounce interval with a minimum duration of 100 ms, which ensures that the electrical and mechanical connection is stable before software attempts to reset the attached device.

ACPI offers two methods that allow us to infer whether or not a USB port is removable. The _PLD method gives us information on whether the port is "user visible" or not. If that's not present then we can fall back to the _UPC method which tells us whether or not a port is connectable.

This adds EHCI host support to the chipidea driver. We want it to be part of the hdrc driver and not a standalone (sub-)driver module, as the structure of ehci-hcd.c suggests, so for chipidea controller we hack it to not provide platform-related code, but only the ehci hcd. The ehci-platform driver won't work for us here too, because the controller uses the same registers for both device and host mode and also otg-related bits, so it's not really possible to put ehci registers into a separate resource. This is not a pretty solution, but the alternative is exporting symbols from the chipidea driver to a ehci-chipidea driver and doing all the module refcounting.

Add some generic code for roles and implement simple role switching based on ID pin state and/or a sysfs file. At this, we also rename the device to ci_hdrc, which is what it is. The "manual" switch is made into a sysfs file and not debugfs, because it might be useful even in non-debug context. For some boards, like sheevaplug, it seems to be the only way to switch roles without modifying the hardware, since the ID pin is always grounded.
