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
