  "message": "usb: Add LED triggers for USB activity\n\nWith this patch, USB activity can be signaled by blinking a LED. There\nare two triggers, one for activity on USB host and one for USB gadget.\n\nBoth triggers should work with all host/device controllers. Tested only\nwith musb.\n\nPerformace: I measured performance overheads on ARM Cortex-A8 (TI\nAM335x) running on 600 MHz.\n\nDuration of usb_led_activity():\n- with no LED attached to the trigger:        2 ± 1 µs\n- with one GPIO LED attached to the trigger:  2 ± 1 µs or 8 ± 2 µs (two peaks in histogram)\n\nDuration of functions calling usb_led_activity() (with this patch\napplied and no LED attached to the trigger):\n- __usb_hcd_giveback_urb():    10 - 25 µs\n- usb_gadget_giveback_request(): 2 - 6 µs\n\nSigned-off-by: Michal Sojka \u003csojka@merica.cz\u003e\nAcked-by: Felipe Balbi \u003cbalbi@ti.com\u003e\nTested-by: Felipe Balbi \u003cbalbi@ti.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n",
