You should avoid using "that patch" in a changelog, since we already
know it is a patch.
You can read 4.c in "The perfect patch" from Andrew Morton:
http://userweb.kernel.org/~akpm/stuff/tpp.txt
> that the fclk nodes can be retrieved by doing a clk_get with the

...or device name.

That comment is not necessarily only for you, but do we have to start
device id at 0?
I think it is really confusing to name the famous gptimer1 device with
"dmtimer.0".
From that list it looks like this is not even consistent across IPs.
McBSP start at 1 for example.
Since we are in the name discussion, I'd like as well to potentially
stop using the dmtimer / gptimer confusing naming convention, and
replace that with a simple name "timer". Or potentially "omap_timer".
Dual Mode timer does not mean at lot and General Purpose timer is not
that better.
We already started that discussion with Kevin some time ago but didn't
really conclude.
Tony, Paul and Kevin,
Do you have any opinion on that subject?
Regards,
Benoit
