Just noticed that it says ts2004 instead of tsc2004 in the subject.
Otherwise, I am fine with it.
Thanks for the assistance.
Still no acks or reviews for the other patches in the series.
I would like for someone to test the tsc2005 support to see if it still works.
The tsc2004 works very well on the target that I have here.
