Power consumption will increase slightly on older boards, VextSmps1 (the external regulator connected to VextSupply1) has a typical quiescent current of 40 uA.

2012-05-22regulator: db5500: Correct propagation to power stateBengt Jonsson
This patch solves an issue with the power state count (which is used when CPUidle takes the decision to go to sleep). When a db5500 regulator is enabled/disabled, the power state count should only be updated if there is a change in the regulator state. Normally, this error is not visible because the regulator framework will check if the regulator is enabled before enabling. But if the suspend/resume functionality of the regulator framework is activated, there may be calls to enable even if the regulator is already enabled.

Handle ABB irq as a nested thread because otherwise the READ_POINTER which indicates which buffer to use for the ABB events could change (after the ack_dbb_wakeup()) before the ABB interrupt handler has a chance to handle it.

2012-05-22mach-ux500: Fixup use of supend|resume_noirqUlf Hansson
Changes needed due to the following commit: PM: Limit race conditions between runtime PM and system sleep (v2) Previously it was was possible for drivers doing pm_runtime_suspend and pm_runtime_put_sync directly from it's suspend callbacks. Now suspend_noirq shall be used, thus this is implemented for AMBA. Additionally pm_runtime is now disabled during system suspend, meaning "pm_runtime_status_suspended" must be used in suspend|resume_noirq context instead of "pm_runtime_suspended".
