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 Conflicts: arch/arm/Kconfig Signed-off-by: Arnd Bergmann <arnd@arndb.de>
