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 Signed-off-by: Arnd Bergmann <arnd@arndb.de>
