Merge tag 'mfd-3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next
Pull MFD update from Samuel Ortiz: "For the 3.11 merge we only have one new MFD driver for the Kontron PLD. But we also have: - Support for the TPS659038 PMIC from the palmas driver. - Intel's Coleto Creek and Avoton SoCs support from the lpc_ich driver. - RTL8411B support from the rtsx driver. - More DT support for the Arizona, max8998, twl4030-power and the ti_am335x_tsadc drivers. - The SSBI driver move under MFD. - A conversion to the devm_* API for most of the MFD drivers. - The twl4030-power got split from twl-core into its own module. - A major ti_am335x_adc cleanup, leading to a proper DT support. - Our regular arizona and wm* updates and cleanups from the Wolfson folks. - A better error handling and initialization, and a regulator subdevice addition for the 88pm80x driver. - A bulk platform_set_drvdata() call removal that's no longer need since commit 0998d0631001 ("device-core: Ensure drvdata = NULL when no driver is bound") * tag 'mfd-3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next: (102 commits) mfd: sec: Provide max_register to regmap mfd: wm8994: Remove duplicate check for active JACKDET MAINTAINERS: Add include directory to MFD file patterns mfd: sec: Remove fields not used since regmap conversion watchdog: Kontron PLD watchdog timer driver mfd: max8998: Add support for Device Tree regulator: max8998: Use arrays for specifying voltages in platform data mfd: max8998: Add irq domain support regulator: palmas: Add TPS659038 support mfd: Kontron PLD mfd driver mfd: palmas: Add TPS659038 PMIC support mfd: palmas: Add SMPS10_BOOST feature mfd: palmas: Check if irq is valid mfd: lpc_ich: iTCO_wdt patch for Intel Coleto Creek DeviceIDs mfd: twl-core: Change TWL6025 references to TWL6032 mfd: davinci_voicecodec: Fix build breakage mfd: vexpress: Make the driver optional for arm and arm64 mfd: htc-egpio: Use devm_ioremap_nocache() instead of ioremap_nocache() mfd: davinci_voicecodec: Convert to use devm_* APIs mfd: twl4030-power: Fix relocking on error ...
