hi ,

I have one question about LED indication on AM3352 platform USB OTG .

I am programming a driver to toggle LED while USB HDD/storage data access.

But i can not find the correct access function that i can toggle LED indicator in kernel.

Could you please tell where i can add LED toggle function in AM3352 kernel to indicate if USB is accessing?
