Yes, I understand it has been coded in haste to assist in debugging
of the driver. Yes, there is a format to it but needs bit of work
I guess, otherwise it will be like opening pandoras box. For now, I will drop
this debugfs patch and later will push with proper explanation of its
need and interface.
Thanks
