usb: move usb/usb-common.c to usb/common/usb-common.c Since we will have more usb-common things, and it will let usb-common.c be larger and larger, we create a folder named usb/common for all usb common things.

usb: Rename usb-common.c In the next commit, we will want the usb-common module to be composed of two object files. Since Kbuild cannot "append" another object to an existing one, we need to rename usb-common.c to something else (common.c) and create usb-common.o by linking the wanted objects together. Currently, usb-common.o comprises only common.o.

usb: Add LED triggers for USB activity With this patch, USB activity can be signaled by blinking a LED. There are two triggers, one for activity on USB host and one for USB gadget. Both triggers should work with all host/device controllers. Tested only with musb. Performace: I measured performance overheads on ARM Cortex-A8 (TI AM335x) running on 600 MHz. Duration of usb_led_activity(): - with no LED attached to the trigger: 2 ± 1 µs - with one GPIO LED attached to the trigger: 2 ± 1 µs or 8 ± 2 µs (two peaks in histogram) Duration of functions calling usb_led_activity() (with this patch applied and no LED attached to the trigger): - __usb_hcd_giveback_urb(): 10 - 25 µs - usb_gadget_giveback_request(): 2 - 6 µs Signed-off-by: Michal Sojka <sojka@merica.cz> Acked-by: Felipe Balbi <balbi@ti.com> Tested-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

usb: common: rename phy-fsm-usb.c to usb-otg-fsm.c Since usb otg fsm implementation is not related to usb phy. We move it from usb/phy/ to usb/common/, and rename it to reflect its real meaning.
