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.
