PM branch updated

Hello,

I just pushed an updated PM branch to my linux-omap-pm repo[1], and it will be sync'd to Tony's linux-omap tree shortly.

What's changed: Not many functional changes, but lots of restructuring to organize/regroup patches into changesets for upstream. In addition to the various fixes coming in from the list, here are some other user-visible changes:

- 600 MHz OPP (a.k.a. overdrive) allowed in CPUfreq
- default CPUfreq governor: userspace, so default OPP is determined by bootloader, and not changed during kernel boot
- UARTs obey /sys/devices/.../power/wakeup
- serial ports separated so each port can be controlled separately under /sys/devices

Basic retention/off while idle and suspend testing on the following OMAP3 boards:

- 3430SDP (NFS root)
- OMAP3EVM (NFS root)
- Beagle (MMC rootfs)
- RX51 (OneNAND rootfs)
- Overo (Water + Tobi) (thanks to Gumstix for the hardware!) ** Known problems: retention during idle eventually hangs with what looks like memory corruption (not debugged further.) Looks like Overo support in linux-omap needs some updates, including a sanity check of the SDRC settings.

Upcoming changes:

The next PM branch will drop the current omapdev code and replace it with the latest versions of omap_hwmod and omap_device code from Paul Walmsely.
