2016-07-17	usb: musb: add tracepoints to dump interrupt events	Bin Liu	1	-0/+21
	This adds tracepoints to dump musb interrupt events. Signed-off-by: Bin Liu <b-liu@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-07-17	usb: musb: add tracepoints for register access	Bin Liu	1	-0/+87
	This adds tracepoints to musb register read/write wrappers to get trace log for register access. The default tacepoint log prefix here would be musb_readX/writeX(), which is not much helpful. So this patch let the tracepoints use __buildin_return_address(0) to print the caller funciton name to provide more context of the register access.
