Merge tag 'ux500-multiplatform-asoc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/multiplatform

From Linus Walleij <linus.walleij@linaro.org>:

Ux500 multiplatform support.  This tag builds upon the MFD-specific base
tag "ux500-multiplatform-mfd". This removes all <mach/*> dependencies
and makes the ux500 fully multi-platform.

* tag 'ux500-multiplatform-asoc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
  ARM: ux500: build hotplug.o for ARMv7-a
  ARM: ux500: move to multiplatform
  ARM: ux500: make remaining headers local
  ARM: ux500: make irqs.h local to platform
  ARM: ux500: get rid of <mach/[hardware|db8500-regs].h>
  staging: ste_rmi4: kill platform_data hack
  ARM: ux500: move mach/msp.h to <linux/platform_data/*>
  clk: ux500: pass clock base adresses in init call
  ARM: ux500: make debug macro stand-alone
  ARM: ux500: move debugmacro to debug includes
  ARM: ux500: split out prcmu initialization
  mfd: db8500-prcmu: drop unused includes
  ARM: ux500: move PM-related PRCMU functions to machine
  mfd: db8500-prcmu: get base address from resource
  mfd: prcmu: pass a base and size with the early initcall
