Merge tag 'omap-for-v3.15/dt-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt

Pull "omap device tree changes for v3.15, part 3" from Tony Lindgren:

Device tree related changes to the omap iommu driver as that
is finally getting updated. Also few trivial board related
.dts updates to add more devices.

* tag 'omap-for-v3.15/dt-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: dts: Add MMC2/SDIO/WLAN support for cm-t3530
  ARM: dts: am335x-evmsk: enable DMA controller for USB
  ARM: dts: OMAP5: Add IOMMU nodes
  ARM: dts: OMAP4: Add IOMMU nodes
  ARM: dts: OMAP3: Add IVA IOMMU node
  ARM: dts: OMAP3: Update ISP IOMMU node
  ARM: OMAP2+: extend iommu pdata-quirks to OMAP5
  ARM: OMAP5: hwmod data: add mmu data for ipu & dsp
  ARM: OMAP2+: use pdata quirks for iommu reset lines
  ARM: OMAP2+: change the ISP device archdata MMU name for DT
  ARM: OMAP3: fix iva mmu programming issues
  ARM: OMAP3: remove deprecated CONFIG_OMAP_IOMMU_IVA2
