Merge tag 'ux500-dma40-for-arm-soc-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/drivers

From Linus Walleij:
Second set of DMA40 changes: refactorings and device tree
support for the DMA40. Now with MUSB and some platform
data removal.

* tag 'ux500-dma40-for-arm-soc-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
  dmaengine: ste_dma40: Fetch disabled channels from DT
  dmaengine: ste_dma40: Fetch the number of physical channels from DT
  ARM: ux500: Stop passing DMA platform data though AUXDATA
  dmaengine: ste_dma40: Allow memcpy channels to be configured from DT
  dmaengine: ste_dma40_ll: Replace meaningless register set with comment
  dmaengine: ste_dma40: Convert data_width from register bit format to value
  dmaengine: ste_dma40_ll: Use the BIT macro to replace ugly '(1 << x)'s
  ARM: ux500: Remove recently unused stedma40_xfer_dir enums
  dmaengine: ste_dma40: Replace ST-E's home-brew DMA direction defs with generic ones
  ARM: ux500: Replace ST-E's home-brew DMA direction definition with the generic one
  dmaengine: ste_dma40: Use the BIT macro to replace ugly '(1 << x)'s
  ARM: ux500: Remove empty function u8500_of_init_devices()
  ARM: ux500: Remove ux500-musb platform registation when booting with DT
  usb: musb: ux500: add device tree probing support
  usb: musb: ux500: attempt to find channels by name before using pdata
  usb: musb: ux500: harden checks for platform data
  usb: musb: ux500: take the dma_mask from coherent_dma_mask
  usb: musb: ux500: move the MUSB HDRC configuration into the driver
  usb: musb: ux500: move channel number knowledge into the driver
