Merge tag 'mfd-for-linus-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd
Pull MFD update from Lee Jones: "Changes to existing drivers: - checkpatch fixes throughout the subsystem - use Regmap to handle IRQs in max77686, extcon-max77693 and mc13xxx-core - use DMA in rtsx_pcr - restrict building on unsupported architectures on timberdale, cs5535 - SPI hardening in cros_ec_spi - more robust error handing in asic3, cros_ec, ab8500-debugfs, max77686 and pcf50633-core - reorder PM runtime and regulator handing during shutdown in arizona - enable wakeup in cros_ec_spi - unused variable/code clean-up in pm8921-core, cros_ec, htc-i2cpld, tps65912-spi, wm5110-tables and ab8500-debugfs - add regulator handing into suspend() in sec-core - remove pointless wrapper functions in extcon-max77693 and i2c-cros-ec-tunnel - use cross-architecture friendly data sizes in stmpe-i2c, arizona, max77686 and tps65910 - devicetree documentation updates throughout - provide power management support in max77686 - few OF clean-ups in max77686 - use manged resources in tps6105x New drivers/supported devices: - add support for s2mpu02 to sec-core - add support for Allwinner A32 to sun6i-prcm - add support for Maxim 77802 in max77686 - add support for DA9063 AD in da9063 - new driver for Intel PMICs (generic) and specifically Crystal Cove (Re-)moved drivers == - move out keyboard functionality cros_ec ==> input/keyboard/cros_ec_keyb" * tag 'mfd-for-linus-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd: (101 commits) MAINTAINERS: Update MFD repo location mfd: omap-usb-host: Fix improper mask use. mfd: arizona: Only free the CTRLIF_ERR IRQ if we requested it mfd: arizona: Add missing handling for ISRC3 under/overclocked mfd: wm5110: Add new interrupt register definitions mfd: arizona: Rename thermal shutdown interrupt mfd: wm5110: Add in the output done interrupts mfd: wm5110: Remove non-existant interrupts mfd: tps65912-spi: Remove unused variable mfd: htc-i2cpld: Remove unused code mfd: da9063: Add support for AD silicon variant mfd: arizona: Map MICVDD from extcon device to the Arizona core mfd: arizona: Add MICVDD to mapped regulators for wm8997 mfd: max77686: Ensure device type IDs are architecture agnostic mfd: max77686: Add Maxim 77802 PMIC support mfd: tps6105x: Use managed resources when allocating memory mfd: wm8997-tables: Suppress 'line over 80 chars' warnings mfd: kempld-core: Correct a variety of checkpatch warnings mfd: ipaq-micro: Fix coding style errors/warnings reported by checkpatch mfd: si476x-cmd: Remedy checkpatch style complains ...
