Hi Greg,

Thanks for the speedy replies. Yes, I will add more background information and make the quick formatting changes for a v2. We'll reply to your other email comments and get those resolved as well. I was trying to be terse but looks like I was too terse. I thought the changelog text should be brief and the cover letter would be more verbose?

Regards,
Dave

A bit more description of exactly _what_ these devices do would be
helpful.

Also, how does userspace interact with the driver?  What api(s) are you
using/creating?  What userspace tools work with the device?

In short, we need more than just a one sentance description to be able
to properly review the code and provide text for a user to know what to
do with this driver.

Can you fix all that up and send a v2?

thanks,
