This series adds the PM debug infrastructure which is
currently used in the OMAP PM branch[1].
Applies on v2.6.31-rc5 plus previous PM fixes queue:
[PATCH 00/14] OMAP PM fixes for .31-rc series
Kevin
[1] http://elinux.org/OMAP_Power_Management
Peter 'p2' De Schrijver (8):
OMAP: PM counter infrastructure.
OMAP: PM: Hook into PM counters
OMAP: PM: Add closures to clkdm_for_each and pwrdm_for_each.
OMAP: PM: Add pm-debug counters
OMAP: PM debug: make powerdomains use PM-debug counters
OMAP: PM: Add definitions for ETK pads and observability registers
OMAP3: Debug observability and ETK padconf implementation
OMAP3: Add debug observablity (debobs) Kconfig item
Tero Kristo (2):
OMAP: PM debug: Add PRCM register dump support
OMAP: PM: Added suspend target state control to debugfs for OMAP3

Also some new fields are added to the powerdomain struct to keep the time information. NOTE: As of v2.6.29, using getnstimeofday() after drivers are suspended is no longer safe since the timekeeping subsystem is also suspended as part of the suspend process. Instead use sched_clock() which on OMAP returns the 32k SYNC timer in nanoseconds.
