Why?  Where was that discussion?

Again, where was that discussion?

Ok, will look at this later.

Really?  I see no description of the ioctls and the structures used in
them, no any explaination of any of the sysfs files used in the driver
in that file.  Please fix this up.  The proper format for all sysfs
files is described in Documentation/ABI/README and the ioctls you can
also use the same format.

It's not clear at all.  Where is the userspace tools that interact with
this driver that allows me to test that the code works properly?  That
would be a good first step as I do have access to this hardware around
here to test with.  Do any distros already have it packaged anywhere?
