Merge tag 'mfd-3.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFD bits from Samuel Ortiz: "We have support for a few new drivers: - Samsung s2mps11 - Wolfson Microelectronics wm5102 and wm5110 - Marvell 88PM800 and 88PM805 - TI twl6041 We also have our regular driver improvements: - Device tree and IRQ domain support for STE AB8500 - Regmap and devm_* API conversion for TI tps6586x - Device tree support for Samsung max77686 - devm_* API conversion for STE AB3100 Besides that, quite a lot of fixing and cleanup for mc13xxx, tps65910, tps65090, da9052 and twl-core." Fix up mostly trivial conflicts, with the exception of drivers/usb/host/ehci-omap.c in particular, which had some re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI: centralize controller initialization") that clashed with commit 2761a6394516 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues"). In particular, commit 2761a6394516 moved the usb_add_hcd() to the *middle* of the reset sequence, which clashes fairly badly with the reset sequence re-organization (although it could have been done inside the new omap_ehci_init() function). I left that part of commit 2761a6394516 just undone. * tag 'mfd-3.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (110 commits) mfd: Ensure AB8500 platform data is passed through db8500-prcmu to MFD Core mfd: Arizone core should select MFD_CORE mfd: Fix arizona-irq.c build by selecting REGMAP_IRQ mfd: Add debug trace on entering and leaving arizone runtime suspend mfd: Correct tps65090 cell names mfd: Remove gpio support from tps6586x core driver ARM: tegra: defconfig: Enable tps6586x gpio gpio: tps6586x: Add gpio support through platform driver mfd: Cache tps6586x register through regmap mfd: Use regmap for tps6586x register access. mfd: Use devm managed resources for tps6586x input: Add onkey support for 88PM80X PMIC mfd: Add support for twl6041 mfd: Fix twl6040 revision information mfd: Matches should be NULL when populate anatop child devices input: ab8500-ponkey: Create AB8500 domain IRQ mapping mfd: Add missing out of memory check for pcf50633 Documentation: Describe the AB8500 Device Tree bindings mfd: Add tps65910 32-kHz-crystal-input init mfd: Drop modifying mc13xxx driver's id_table in probe ...

+* AB8500 Multi-Functional Device (MFD)
+
+Required parent device properties:
+- compatible : contains "stericsson,ab8500";
+- interrupts : contains the IRQ line for the AB8500
+- interrupt-controller : describes the AB8500 as an Interrupt Controller (has its own domain)
+- #interrupt-cells : should be 2, for 2-cell format
+ - The first cell is the AB8500 local IRQ number
+ - The second cell is used to specify optional parameters
+ - bits[3:0] trigger type and level flags:
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive
+
+Optional parent device properties:
+- reg : contains the PRCMU mailbox address for the AB8500 i2c port
+
+The AB8500 consists of a large and varied group of sub-devices:
