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 at vger.kernel.org/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?

regards,
Rajendra

- 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.
