I've unintentionally answered off-line, sorry, re-adding all Cc:'s.

If you still ask me for my opinion: with patch 3/5 omitted, then not 
being able to run at any other frequency than 60 MHz instead of usual 
150 since the board support was introduced first, isn't this a 
regression? Having a choice of upgrading to 3.2 and running my 
application on not very powerfull board at 60 MHz, or keep running 3.1 
at 150, guess what I chose? If I were a distro kernel package 
maintainer, guess what I would chose?

This was not an issue before dpll1 reprogramming has been moved out from 
omap1_clk_init(), as an rc fix to another bug introduced in 3.2. Perhaps 
we should rather think of reverting a few commits which caused all these 
problems if fixing them all during rc cycle seems not possible? I 
haven't bisected them yet, rather concentrated on providing fixes, but I 
can still try to do it, starting back from the original issue 
(http://www.spinics.net/lists/linux-omap/msg60052.html), if so decided.

I don't feel like a person who makes the final decision.

Anyway, did you mean resending those 2/5 and 5/5 without any changes, 
only renumbered as 1/2 and 2/2?

Thanks,
