…arm/arm-soc

Pull ARM SoC board updates, take 2 from Olof Johansson:
 "This branch contains board updates for shmobile that had dependencies
  on earlier branches past the first driver branch, and thus are merged
  separately.

  Most of these are to enable audio and USB on shmobile.  They contain a
  dependent ASoC branch that has been coordinated with Mark Brown."

* tag 'boards2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  ARM: shmobile: mackerel: Add FLCTL IRQ resource
  ARM: shmobile: use FSI driver's audio clock on ap4evb
  ARM: shmobile: use FSI driver's audio clock on mackerel
  ARM: shmobile: use FSI driver's audio clock on armadillo800eva
  ARM: shmobile: mackerel: enable DMAEngine on USB Host
  ARM: shmobile: marzen: add USB OHCI driver support
  ARM: shmobile: marzen: add USB EHCI driver support
  ARM: shmobile: marzen: add USB phy support
  ASoC: fsi: add master clock control functions
  ASoC: fsi: care fsi_hw_start/stop() return value
  ASoC: fsi: fsi_set_master_clk() was called from fsi_hw_xxx() only
  ASoC: fsi: use devm_request_irq()
  ASoC: fsi: fixup channels_min/max
