Merge tag 'vexpress/updates-for-3.16' of git://git.linaro.org/people/pawel.moll/linux into next/cleanup
Merge "ARM Versatile Express updates for 3.16" from Pawel Moll: This series reworks VE's platform configuration infrastructure by: - making it possible to instantiate selected devices from the Device Tree, prior to massive population, - converting custom "func" API into standard "regmap", - splitting the existing MFD driver into smaller ones and placing them into relevant directories. The common clock framework driver can now be selected individually (mostly for arm64 sake, where some of them are not used at all). It also simplifies the machine code, by: - moving the shed clock info clocksource driver, - simplifying SMP operations to base them entirely of the DT data, - moving platform ID checks into relevant driver. * tag 'vexpress/updates-for-3.16' of git://git.linaro.org/people/pawel.moll/linux: ARM: vexpress: move HBI check to sysreg driver ARM: vexpress: Simplify SMP operations for DT-powered system ARM: vexpress: remove redundant vexpress_dt_cpus_num to get cpu count clocksource: Sched clock source for Versatile Express clk: versatile: Split config options for sp810 and vexpress_osc mfd: vexpress: Define the device as MFD cells mfd: syscon: Add platform data with a regmap config name mfd: vexpress: Convert custom func API to regmap of: Keep track of populated platform devices + Linux 3.15-rc5 Signed-off-by: Olof Johansson <olof@lixom.net>
