Hi,

Changes compared to previous version:

Did you get a chance to look at the issue I reported about autodeps?
http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg72876.html

Not really, I didn't think that bug report was meant for me, I kind of
thought it only happened with your set. But now looking at your email in
detail, I guess you are saying there is a bug in this code (the one that
touches iclk stuff), which causes the USB / DSS domains to follow
MPU/CORE, is that right?

Yes, basically the autodeps remain set, even while the module is not in
use at all, which causes them to come in and out of sleep along with MPU.

- Fixed OMAP4 support (patches 7-10)
- Dropped debugging support from this set for now
- Rebased on top of 3.6-rc5 + func-pwrst + omap4-ret code
    (omap4 support easier to test with these)
- Patch #1:
    * dropped clkdm_usecount_inc / clkdm_usecount_dec APIs
    * clkdm_clk_enable / disable are used now instead
    * some code ordering changed for the new setup to work properly
    * changed BUG_ON calls to WARN_ON
- Patch #2:
    * added spinlock for protecting voltdm callbacks
    * pwrdm lock extended to protect pwrdm callbacks
- Patch #3:
    * dropped generic API call for the cpu pwrdm idle / wakeup
    * instead use pwrdm_clkdm_enable / disable calls directly from PM code
    * omap4 support fixed to work properly with SMP, added omap4 specific
      CPU pwrdm idle / wakeup calls for this purpose
- Patch #4:
    * no changes
    * added 'Reviewed-by' tag for Rajendra
- Patch #5:
    * no changes, just rebase
- Patch #6:
    * no changes

Tested with OMAP3 beagle, omap4460 GP panda + omap4430 EMU blaze boards.

I will be posting new versions for the voltdm fixes + auto retention +
panda board tps6236x support code later on today, which are based on top
of this set.
