At the Linaro Connect Asia 2013, a status of the different cpuidle
drivers available upstream have been presented [1].

It was statued there is a lot of common code, especially in the
init routine, and code duplication (eg. ux500 vs imx6).

The following patchset is the first stone to a single ARM driver
consolidating all the common routine used in the different drivers.

The patchset has been tested on ux500 and at91, compiled on all the other
platforms.

Daniel Lezcano (11):
  cpuidle : handle clockevent notify from the cpuidle framework
  cpuidle / arm : a single cpuidle driver
  cpuidle / ux500 : use common ARM cpuidle driver
  cpuidle / omap3 : use common ARM cpuidle driver
  cpuidle / davinci : use common ARM driver
  cpuidle / at91 : use common ARM cpuidle driver
  cpuidle / shmobile : use common ARM cpuidle driver
  cpuidle / imx : use common ARM cpuidle driver
  cpuidle / s3c64xx : use common ARM cpuidle driver
  cpuidle / calxeda : use common ARM cpuidle driver
  cpuidle / kirkwood : use common ARM cpuidle driver
