Hi Rajesh,

can you provide instructions on how to test that this driver does what
it's supposed to? I could probably figure out how to run this with the
kernel's built-in dmatest module, but if you could provide a set of
parameters that you've used or other instructions on how to validate
this it would greatly help.

Thanks,
Thierry
