Merge tag 'armsoc-cleanups-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups and fixes from Arnd Bergmann:
 "Traditionally we've had two separate branches for cleanups and
  non-critical bug fixes, but both of these got smaller with each
  release and the differences are rather unclear now, so it seems more
  appropriate to have a combined branch.

  The most notable change is for OMAP, which gets a small rework to
  simplify handling of the AUXDATA mechanism used on machines that are
  not completely DT based yet, along with other work that is used as
  preparation for dropping the legacy board files"

* tag 'armsoc-cleanups-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  ARM: dts: exynos: Add interrupt line to MAX8997 PMIC on exynos4210-trats
  ARM: dts: exynos: Fix regulator name to avoid forbidden character on exynos4210-trats
  ARM: dts: exynos: Add MFC memory banks for Peach boards
  ARM: OMAP2+: n900 needs MMC slot names for legacy user space
  ARM: OMAP2+: Add more functions to pwm pdata for ir-rx51
  ARM: debug: remove extraneous DEBUG_HI3716_UART option
  ARM: OMAP2+: Simplify auxdata by using the generic match
  of/platform: Allow secondary compatible match in of_dev_lookup
  ARM: davinci: use IRQCHIP_DECLARE for cp_intc
  ARM: davinci: remove unused DA8XX_NUM_UARTS
  ARM: davinci: simplify call to of populate
  ARM: DaVinci USB: removed deprecated properties from MUSB config
