The PM branch hosted in my linux-omap-pm repo[1] has been updated.
Significant changes:
- rebased to omap/master (currently v2.6.31-rc1)
- Using new omap_hwmod and omap_device infrastructure from Paul Walmsley
- more reorg into groups of commits for easier submission upstream
Tested on the following platforms using omap3_pm_defconfig with
busybox-based initramfs, and tested full-chip RET and OFF in idle and
suspend:
- 3430SDP
- OMAP3EVM
- Beagle
- Overo
- RX51
- Zoom2 (use 'pm-staging/zoom2' branch as well, which is Vikram's
zoom2 branch rebased on top of PM branch with DEBUG_LL
support and misc. fixes)
Known problems:
- no DVFS because of next item...
- SRF driver broken, needs update for new hwmod/omap_device layer
(default config used PM NOOP)
- network drivers and off-mode
- various hangs when using off-while-idle and NFS-mounted rootfs
- network drivers likely need some context save/restore support
- SDRAM on 2 CSes (Beagle, Overo, RX51)
- need to boot with mem=128M so only a single CS is used
- 2 CS support patches from Jean Pihet solve this problem,
but not yet merged.
- 3430SDP ES3.0
- UART1 doesn't come back from off-while-idle (ok on es3.1 SDP)
