Merge tag 'timer' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: timer cleanup work" from Arnd Bergmann: "These are split out from the generic soc and driver updates because there was a lot of conflicting work by multiple people. Marc Zyngier worked on simplifying the "localtimer" interfaces, and some of the platforms are touching the same code as they move to device tree based booting. Signed-off-by: Arnd Bergmann <arnd@arndb.de>" * tag 'timer' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (61 commits) ARM: tegra: select USB_ULPI if USB is selected arm/tegra: pcie: fix return value of function ARM: ux500: fix compilation after local timer rework ARM: shmobile: remove additional __io() macro use ARM: local timers: make the runtime registration interface mandatory ARM: local timers: convert MSM to runtime registration interface ARM: local timers: convert exynos to runtime registration interface ARM: smp_twd: remove old local timer interface ARM: imx6q: convert to twd_local_timer_register() interface ARM: highbank: convert to twd_local_timer_register() interface ARM: ux500: convert to twd_local_timer_register() interface ARM: shmobile: convert to twd_local_timer_register() interface ARM: tegra: convert to twd_local_timer_register() interface ARM: plat-versatile: convert to twd_local_timer_register() interface ARM: OMAP4: convert to twd_local_timer_register() interface ARM: smp_twd: add device tree support ARM: smp_twd: add runtime registration support ARM: local timers: introduce a new registration interface ARM: smp_twd: make local_timer_stop a symbol instead of a #define ARM: mach-shmobile: default to no earlytimer ...
