After a double check, the two patches are not merged to 3.2, but have
been merged to the latest linus tree and can be seen in 3.3-rc1.

Also the commit 3c50729b(ARM: OMAP4: PM: Initialise all the clockdomains
to supported states) has been merged to linus tree too.

So if you just tested the latest linus tree simply, you need to apply
the patch[1]
(I have mentioned the problem in the thread.)
