Mark Brown	90ca2979ed	ARM: S3C64XX: Reduce residency requirement for cpuidle WFI mode ... Entering and leaving WFI is really cheap so there's no reason to have much of a residency requirement for the state. Lower it to 1ms.

Mark Brown	2abf13c9ff	ARM: S3C64XX: Add basic cpuidle driver ... Add a very basic cpuidle driver for S3C64xx which merely drives the CPU into IDLE mode. We could do this with pm_idle but the more modern idiom is to use cpuidle and the intention is to go further and support STOP and DEEP-STOP states in conjunction with the pm_domain framework. The actual state entry code was lifted from Tomasz Figa's work on spica.
