Merge tag 'omap-for-v3.10/timer-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers

From Tony Lindgren <tony@atomide.com>:

Clean-up for omap2+ timers from Jon Hunter <jon-hunter@ti.com>:

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.

Note that this series depends on 7185684 (ARM: OMAP: use
consistent error checking) in RMK's tree and 960cba6 (ARM:
OMAP5: timer: Update the clocksource name as per clock data)
in omap-for-v3.10/fixes-non-critical. So this branch is based
on a merge of 7185684 and omap-for-v3.10/fixes-non-critical
to avoid non-trivial merge conflicts.

* tag 'omap-for-v3.10/timer-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP4+: Fix sparse warning in system timers
  ARM: OMAP2+: Store ID of system timers in timer structure
  ARM: OMAP3: Update clocksource timer selection
  ARM: OMAP2+: Simplify system timers definitions
  ARM: OMAP2+: Simplify system timer clock definitions
  ARM: OMAP2+: Remove hard-coded test on timer ID
  ARM: OMAP2+: Display correct system timer name
  ARM: OMAP2+: fix typo "CONFIG_BRIDGE_DVFS"
  ARM: OMAP1: remove "config MACH_OMAP_HTCWIZARD"
  ARM: OMAP: dpll: enable bypass clock only when attempting dpll bypass
  ARM: OMAP2+: powerdomain: avoid testing whether an unsigned char is less than 0
  ARM: OMAP2+: hwmod: Remove unused _HWMOD_WAKEUP_ENABLED flag
  ARM: OMAP2+: am335x: Change the wdt1 func clk src to per_32k clk
  ARM: OMAP2+: AM33xx: hwmod: Add missing sysc definition to wdt1 entry
