[PATCH 00/10] ARM: OMAP: DMTIMER fixes and clean-up

This series includes several fixes for the OMAP DMTIMER driver and a few
clean-ups to simplify some of the code. This series is based upon 3.6-rc4.

Tested on OMAP5912 OSK, OMAP2420 H4, OMAP3430 Beagle and OMAP4430 Panda.
Testing includes ...
1. Booting kernel on above boards
2. Set date and ensuring time of day is correct after 24 hours
3. Checking the timer counter is incrementing when configuring and starting
   a timer
4. Checking the timer overflow interrupt when timer expires.
5. Using different clock sources to operate the timer with.
6. Running a loop test overnight that continually runs test #3 and #4 for
   each available timer

On the other hand I have validated this patch-series on both AM37xEVM
and BeagleBone platform. I used the test code which you shared with me
to validate it.

AM33XX Clock tree needs minor change here,
