Merge tag 'mfd_3.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFD changes from Samuel Ortiz: - 4 new drivers: Freescale i.MX on-chip Anatop, Ricoh's RC5T583 and TI's TPS65090 and TPS65217. - New variants support (8420, 8520 ab9540), cleanups and bug fixes for the abx500 and db8500 ST-E chipsets. - Some minor fixes and update for the wm8994 from Mark. - The beginning of a long term TWL cleanup effort coming from the TI folks. - Various fixes and cleanups for the s5m, TPS659xx, pm860x, and MAX8997 drivers. Fix up trivial conflicts due to duplicate patches and header file cleanups (<linux/device.h> removal etc). * tag 'mfd_3.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (97 commits) gpio/twl: Add DT support to gpio-twl4030 driver gpio/twl: Allocate irq_desc dynamically for SPARSE_IRQ support mfd: Detach twl6040 from the pmic mfd driver mfd: Replace twl-* pr_ macros by the dev_ equivalent and do various cleanups mfd: Micro-optimization on twl4030 IRQ handler mfd: Make twl4030 SIH SPARSE_IRQ capable mfd: Move twl-core IRQ allocation into twl[4030|6030]-irq files mfd: Remove references already defineid in header file from twl-core mfd: Remove unneeded header from twl-core mfd: Make twl-core not depend on pdata->irq_base/end ARM: OMAP2+: board-omap4-*: Do not use anymore TWL6030_IRQ_BASE in board files mfd: Return twl6030_mmc_card_detect IRQ for board setup Revert "mfd: Add platform data for MAX8997 haptic driver" mfd: Add support for TPS65090 mfd: Add some da9052-i2c section annotations mfd: Build rtc5t583 only if I2C config is selected to y. mfd: Add anatop mfd driver mfd: Fix compilation error in tps65910.h mfd: Add 8420 variant to db8500-prcmu mfd: Add 8520 PRCMU variant to db8500-prcmu ...
