Also those drivers you did not mention in your list are called retu-user and tahvo-user (both in drivers/cbus/ in kernel source) and the whole point of having them in kernel is allowing banging HW registers from userspace. They only offer IOCTL for that, nothing else.

Two examples of abandoned hardware Posted Apr 12, 2007 19:18 UTC (Thu) by oak (subscriber, #2786) [Link] There was a good article on misconception about "somewhere" beingsome perfect documentation for the hardware that the "evil" people had "plotted" to keep away from the open source developers, but unfortunately I couldn't find that article now. Basically it said that many of the device drivers just "bang some HW registers" and only documentation available (anywhere) is the code banging those HW registers. And the "magic" values in the code are something that have been found to work by experimentation. :-)
Two examples of abandoned hardware Posted Apr 12, 2007 20:17 UTC (Thu) by dufkaf (subscriber, #10358) [Link] well one could log all reads and writes that go through those *-user drivers together with pid of calling process so we could guess what those closed userspace parts do ...
