Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (59 commits) rtc: max8925: Add function to work as wakeup source mfd: Add pm ops to max8925 mfd: Convert aat2870 to dev_pm_ops mfd: Still check other interrupts if we get a wm831x touchscreen IRQ mfd: Introduce missing kfree in 88pm860x probe routine mfd: Add S5M series configuration mfd: Add s5m series irq driver mfd: Add S5M core driver mfd: Improve mc13xxx dt binding document mfd: Fix stmpe section mismatch mfd: Fix stmpe build warning mfd: Fix STMPE I2c build failure mfd: Constify aat2870-core i2c_device_id table gpio: Add support for stmpe variant 801 mfd: Add support for stmpe variant 801 mfd: Add support for stmpe variant 610 mfd: Add support for STMPE SPI interface mfd: Separate out STMPE controller and interface specific code misc: Remove max8997-muic sysfs attributes mfd: Remove unused wm831x_irq_data_to_mask_reg() ... Fix up trivial conflict in drivers/leds/Kconfig due to addition of LEDS_MAX8997 and LEDS_TCA6507 next to each other.
