Merge tag 'mfd-for-linus-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFD fixes from Samuel Ortiz: "We have 3 build fixes, a OMAP USB host PHY reset fix and the twl6040 conversion to an i2c driver. The latter may not sound like a fix but the twl6040 MFD driver won't probe without it, triggering an OMAP4 audio regression." * tag 'mfd-for-linus-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: mfd: Fix modular builds of rc5t583 regulator support mfd: Fix asic3_gpio_to_irq ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issue mfd: Convert twl6040 to i2c driver, and separate it from twl core mfd : Fix dbx500 compilation error
