Pull ARM SoC fixes from Arnd Bergmann:
 "Here are a bunch of small bug fixes for various ARM platforms, nothing
  really sticks out this week, most of either fixes bugs in code that
  was just added in 4.4, or that has been broken for many years without
  anyone noticing.

  at91/sama5d2:
   - fix sama5de hardware setup of sd/mmc interface
   - proper selection of pinctrl drivers.  PIO4 is necessary for sama5d2

  berlin:
   - fix incorrect clock input for SDIO

  exynos:
   - Fix potential NULL pointer dereference in Exynos PMU driver.

  imx:
   - Fix vf610 SAI clock configuration bug which is discovered by the
     newly added master mode support in SAI audio driver.
   - Fix buggy L2 cache latency values in vf610 device trees, which may
     cause system hang when cpu runs at a higher frequency.

  ixp4xx:
   - fix prototypes for readl/writel functions

  ls2080a:
   - use little-endian register access for GPIO and SDHCI

  omap:
   - Fix clock source for ARM TWD and global timers on am437x
   - Always select REGULATOR_FIXED_VOLTAGE for omap2+ instead of when
     MACH_OMAP3_PANDORA is selected
   - Fix SPI DMA handles for dm816x as only some were mapped
   - Fix up mbox cells for dm816x to make mailbox usable

  pxa:
   - use PWM lookup table for all ezx machines

  s3c24xx:
   - Remove incorrect __init annotation from s3c24xx cpufreq driver
     structures.

  versatile:
   - fix PCI IRQ mapping on Versatile PB"
