Merge tag 'mfd-3.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFD changes from Samuel Ortiz: "Besides the usual cleanups, this one brings: * Support for 5 new chipsets: Intel's ICH LPC and SCH Centerton, ST-E's STAX211, Samsung's MAX77693 and TI's LM3533. * Device tree support for the twl6040, tps65910, da9502 and ab8500 drivers. * Fairly big tps56910, ab8500 and db8500 updates. * i2c support for mc13xxx. * Our regular update for the wm8xxx driver from Mark." Fix up various conflicts with other trees, largely due to ab5500 removal etc. * tag 'mfd-3.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (106 commits) mfd: Fix build break of max77693 by adding REGMAP_I2C option mfd: Fix twl6040 build failure mfd: Fix max77693 build failure mfd: ab8500-core should depend on MFD_DB8500_PRCMU gpio: tps65910: dt: process gpio specific device node info mfd: Remove the parsing of dt info for tps65910 gpio mfd: Save device node parsed platform data for tps65910 sub devices mfd: Add r_select to lm3533 platform data gpio: Add Intel Centerton support to gpio-sch mfd: Emulate active low IRQs as well as active high IRQs for wm831x mfd: Mark two lm3533 zone registers as volatile mfd: Fix return type of lm533 attribute is_visible mfd: Enable Device Tree support in the ab8500-pwm driver mfd: Enable Device Tree support in the ab8500-sysctrl driver mfd: Add support for Device Tree to twl6040 mfd: Register the twl6040 child for the ASoC codec unconditionally mfd: Allocate twl6040 IRQ numbers dynamically mfd: twl6040 code cleanup in interrupt initialization part mfd: Enable ab8500-gpadc driver for Device Tree mfd: Prevent unassigned pointer from being used in ab8500-gpadc driver ...
