	depends on I2C=y && OF
	help
	  The ams AS3722 is a compact system PMU suitable for mobile phones,
	  tablets etc. It has 4 DC/DC step-down regulators, 3 DC/DC step-down
	  controllers, 11 LDOs, RTC, automatic battery, temperature and
	  over current monitoring, GPIOs, ADC and a watchdog.

config PMIC_ADP5520
	bool "Analog Devices ADP5520/01 MFD PMIC Core Support"
	depends on I2C=y
	help
	  Say yes here to add support for Analog Devices AD5520 and ADP5501,
	  Multifunction Power Management IC. This includes
	  the I2C driver and the core APIs _only_, you have to select
	  individual components like LCD backlight, LEDs, GPIOs and Kepad
	  under the corresponding menus.

config MFD_AAT2870_CORE
	bool "AnalogicTech AAT2870"
	select MFD_CORE
	depends on I2C=y && GPIOLIB
	help
	  If you say yes here you get support for the AAT2870.
	  This driver provides common support for accessing the device,
	  additional drivers must be enabled in order to use the
	  functionality of the device.

config MFD_BCM590XX

	  Support for the BCM590xx PMUs from Broadcom

config MFD_CROS_EC
	tristate "ChromeOS Embedded Controller"
	select MFD_CORE
	help
	  If you say Y here you get support for the ChromeOS Embedded
	  Controller (EC) providing keyboard, battery and power services.
	  You also need to enable the driver for the bus you are using. The
	  protocol for talking to the EC is defined by the bus driver.

config MFD_CROS_EC_I2C
	tristate "ChromeOS Embedded Controller (I2C)"
	depends on MFD_CROS_EC && I2C

	help
	  If you say Y here, you get support for talking to the ChromeOS
	  EC through an I2C bus. This uses a simple byte-level protocol with
	  a checksum. Failing accesses will be retried three times to
	  improve reliability.

config MFD_CROS_EC_SPI
	tristate "ChromeOS Embedded Controller (SPI)"
	depends on MFD_CROS_EC && SPI && OF

	---help---
	  If you say Y here, you get support for talking to the ChromeOS EC
	  through a SPI bus, using a byte-level protocol. Since the EC's
	  response time cannot be guaranteed, we support ignoring
	  'pre-amble' bytes before the response actually starts.

config MFD_ASIC3
	bool "Compaq ASIC3"
	depends on GPIOLIB && ARM
	select MFD_CORE
	 ---help---
	  This driver supports the ASIC3 multifunction chip found on many
	  PDAs (mainly iPAQ and HTC based ones)

config PMIC_DA903X

	depends on I2C=y
	help
	  Say yes here to add support for Dialog Semiconductor DA9030 (a.k.a
	  ARAVA) and DA9034 (a.k.a MICCO), these are Power Management IC
	  usually found on PXA processors-based platforms. This includes
	  the I2C driver and the core APIs _only_, you have to select
	  individual components like LCD backlight, voltage regulators,
	  LEDs and battery-charger under the corresponding menus.

	  Say yes here for support of Dialog Semiconductor DA9055. This is
	  a Power Management IC. This driver provides common support for
	  accessing the device as well as the I2C interface to the chip itself.
	  Additional drivers must be enabled in order to use the functionality
	  of the device.

	  This driver can be built as a module. If built as a module it will be
	  called "da9055"
