[PATCH 0/3] OMAP4: CPUidle: Add coupled idle support

The series adds the coupled cpuidle support for OMAP4 based on the v2
series posted [1]. This makes OMAP4 to support SMP cpuidle and also
removes the hard dependency of off-lining CPU1 to trigger deeper
C-states.

I have put together a branch which is based on 3.3 kernel with
Len Browns next branch [2] which has time keeping and other cpuidle
patches which will mostly get merged by 3.4-rc1 and rebased coupled
idle series from [1].

Special thanks to Kevin Hilman and Colin Cross on their help on this
series.
