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
