Cover letter [PATCH 00/11] Fixes for omap PM for making omap3 DT only

I'm on vacation from tomorrow until next week's weekend, but I will have a look the week after next (if still needed).
OK

I have not yet read much of TWL/OMAP PM documentation, but I wonder if it makes sense to move the powerscripting stuff into the DTS file somehow. On a first look the added N900 tables in
drivers/mfd/twl4030-power.cseem like a step back to me.
Need to think about it a bit more, but I think we can have generic scripts based on the tables in "Recommended Sleep Sequences for the Zoom Platform" pdf at:
http://omappedia.com/wiki/File:Recommended_Sleep_Sequences_Zoom.pdf
Then we can have a function that patches in board specific stuff as needed as changes to the generic rconfig table.
I'll take a look at that, let's see how that works. If that works, the board specific increments to the generic data should be pretty small and the data can easily live in the twl4030-power.c with no need to stuff it into the .dts files.
BTW, the situation is also a bit different from the original N900 kernel as we now have runtime PM and drivers can easily manage their regulators.
Regards,
Tony
