Jean Pihet c166381d40 OMAP2+: disable idle early in the suspend sequence
Some bad interaction between the idle and the suspend paths has been
identified: the idle code is called during the suspend enter and exit
sequences. This could cause corruption or lock-up of resources.

The solution is to move the calls to disable_hlt at the very beginning
of the suspend sequence (ex. in omap3_pm_begin instead of
omap3_pm_prepare), and the call to enable_hlt at the very end of
the suspend sequence (ex. in omap3_pm_end instead of omap3_pm_finish).

Tested with RET and OFF on Beagle and OMAP3EVM.

Rajendra Nayak 5643aebbc0 omap4: suspend: Add basic system suspend support
This patch adds support for basic suspend doing a CPUx wfi
for OMAP4. All powerdomains are for now are kept programmed
in ON state.
