[PATCH v2 0/4] OMAP4: CPUidle: Add coupled idle support

Now Colin's v3 [1] is apearing in Len Brown's next branch, I have rebased
OMAP4 support against it. I need to pick up couple of fixes [2] posted on
top of v3 [1] version and arm-soc 'omap/cpuidle-cleanup' branch lined up
for 3.5.

This series adds the coupled cpuidle support for OMAP4 and also removes
the hard dependency of off-lining CPU1 to trigger deeper CPU C-states.
It has been build tested for all OMAP builds and functionally tested
on OMAP4430 SDP.

I have put together a branch with:
1) Len Brown's 'next'
	: git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux 
2) ARM-SOC 'omap/cpuidle-cleanup'
	: git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
3) Two couple_idle_fixes picked up from [2]

And same is available:


Kevin Hilman (1):
  ARM: OMAP4: CPUidle: add synchronization for coupled idle states

Santosh Shilimkar (3):
  ARM: OMAP: timer: allow gp timer clock-event to be used on both cpus
  ARM: OMAP4: CPUidle: Use coupled cpuidle states to implement SMP
  ARM: OMAP4: CPUidle: Open broadcast clock-event device.
