Hi all,

Here's v3 series to udpate omaps to use drivers/clocksource timers for
the 32k counter and dmtimer, and to remove the old legacy platform code.
Please review and test.

I've updated the timer-ti-dm-systimer.c patch based on the comments from
Daniel and Rob, and added support for selecting the preferred timers to
use.

Then for merging when folks are happy with this series, Daniel if you
can please apply the first three patches into an immutable branch it
would be great.

Regards,

Tony


Changes since v2:

- Drop extra compatible and use timer capabilities instead as suggested
  by Rob

- Add support for detecting the preferred system timers to use

Changes since v1:

- Updated to be self-contained based on comments from Daniel

Oops sorry, just first two are needed as we no longer need the
device tree binding changes :)
