[PATCH V3 0/7] ARM: OMAP2+: System timer updates

This series consists mainly of clean-ups for clockevents and
clocksource timers on OMAP2+ devices. The most significant change
in functionality comes from the 5th patch which is changing the
selection of the clocksource timer for OMAP3 and AM335x devices
when gptimers are used for clocksource. This change came about from
Vaibhav Bedia's series for AM335x [1]. See patch for more details on
the exact nature of the change.

Boot tested with and without  device-tree on OMAP2420 H4, OMAP3430 SDP,
OMAP3430 Beagle Board, OMAP4430 SDP and AM335x EVM (AM335x only
supports device-tree boot). Also boot tested boards with kernel boot
parameter "clocksource=gp_timer".

This series is based upon ARM-SoC next branch.

V3 changes:
- Post the intended patches this time!
- Use PTR_ERR() to return the error code if clk_get() fails (thanks
  Russell!)

V2 changes:
- Fixed bug in patch that updates clocksource and clockevents timer
  names to use the hwmod timer names (thanks Vaibhav Bedia!)
- Updated patch that removes the hard-coded ID test to return an error
  as soon as clk_set_parent fails instead of waiting for the end of the
  function.
- Fixed bug in patches that "simplify system timer clock definitions"
  and "simplify system timer definitions" that was prevent omap4/5
  boards from booting with kernel boot parameter "clocksource=gp_timer".
- Updated changelog for patch "simplify system timer definitions" per
  feedback received from Igor.
- Added new patch to store the timer ID in the omap_dm_timer structure
  to clean-up the code.
- Added new patch to fix a sparse warning seen in ARM-SOC next.
