Subject: [PATCH -rt 3/4] ARM: OMAP: Add clocksource driver for OMAP

ARM: OMAP: Add clocksource driver for OMAP.

This is an update of

http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=3876/1

from Daniel Walker and Kevin Hilman.

Changes from Dirk Behme:

       - Apply cleanly to recent kernel (pt_regs change)
       - Move clocksource init to extra function. Can be called
         later by clocksource subsystem
       - Remove warning: 'omap_32k_timer_handler' defined but
not used
         when CONFIG_NO_IDLE_HZ isn't set.
       - Minor cleanups

Changes from David Brownell:

       - OMAP1, OMAP2: 32k clocksource is always available on
16xx and 24xx
       - OMAP1 MPU timer:
           * consult clock framework to determine xtal clock
           * bugfix sched_clock() low order bits
           * cleanup
       - Kconfig updates

Note that "MPU timer" still doesn't have lost tick support.
