Btw, when testing this I found that generic cpu_suspend seems to be just
fine for OMAP3; the OMAP platforms though do not at this time use the
generic cpu_suspend/resume for sleep, is it planned to change that ?

That's because OMAP was doing changes to their sleep code while I was
consolidating the sleep code, and although I asked several times that
the OMAP folk should participate in this effort, but evidentally I was
unsuccessful in achieving anything in that direction.

Agreed but the situation at that point was the code was not at
all in convertible position. Looking at your below comment,
it's still not :)

Well, I had a look before posting this reply, and ran away from it.
I've gone back to it several times since, and got a similar reaction.

I seem to remember that it looked _more_ convertable when I looked at
it when doing the generic suspend/resume support - I could see a nice
simple way to pull out the saving and just leave the PLL resume stuff
in SRAM.

I'm now convinced that if I try to convert it use the generic support,
it will end up being a horrible broken mess.
