Merge tag 'mfd-3.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFD changes from Samuel Ortiz: "MFD bits for the 3.7 merge window. As usual we have a few new drivers: - TI LP8788 - TI OMAP USB TLL - Maxim MAX8907 - SMSC ECE1099 - Dialog Semiconductor DA9055 - A simpler syscon driver that allow us to get rid of the anatop one. Drivers are also gradually getting Device Tree and IRQ domain support. The following drivers got DT support: - palmas, 88pm860x, tc3589x and twl4030-audio And those ones now use the IRQ domain APIs: - 88pm860x, tc3589x, db8500_prcmu Also some other interesting changes: - Intel's ICH LPC now supports Lynx Point - TI's twl4030-audio added a GPO child - tps6527 enabled its backlight subdevice - The twl6030 pwm driver moved to the new PWM subsystem And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family." Fix up various annoying conflicts: the DT and IRQ domain support came in twice and was already in 3.6. And then it was apparently rebased. Guys, DON'T REBASE! * tag 'mfd-3.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (89 commits) ARM: dts: Enable 88pm860x pmic mfd: 88pm860x: Move gpadc init into touch mfd: 88pm860x: Device tree support mfd: 88pm860x: Use irqdomain mfd: smsc: Add support for smsc gpio io/keypad driver backlight: tps65217_bl: Add missing platform_set_drvdata in tps65217_bl_probe mfd: DA9055 core driver mfd: tps65910: Add alarm interrupt of TPS65910 RTC to mfd device list mfd: wm5110: Add register patches for revision B mfd: wm5110: Disable control interface error report for WM5110 rev B mfd: max8907: Remove regulator-compatible from DT docs backlight: Add TPS65217 WLED driver mfd: Add backlight as subdevice to the tps65217 mfd: Provide the PRCMU with its own IRQ domain mfd: Fix max8907 sparse warning mfd: Add lp8788 mfd driver mfd: dbx500: Provide a more accurate smp_twd clock mfd: rc5t583: Fix warning messages regulator: palmas: Add DT support mfd: palmas: Change regulator defns to better suite DT ...
