* usb: musb: add tracepoints for register accessBin Liu2016-07-171-0/+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.

* usb: musb: add tracepoints support for debuggingBin Liu2016-07-171-0/+54
To avoid printk() overhead while debugging, this patch implements the foundation of tracepoints logging for musb driver to make debug easier. Signed-off-by: Bin Liu <b-liu@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
