---help---
This is the core driver for CS5535/CS5536 MFD functions. This is
necessary for using the board's GPIO and MFGPT functionality.

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.

bool "X-Powers AXP20X"
select MFD_CORE
select REGMAP_I2C
select REGMAP_IRQ
depends on I2C=y
help
If you say Y here you get support for the X-Powers AXP202 and AXP209.
This driver include only the core APIs. You have to select individual
components like regulators or the PEK (Power Enable Key) under the
corresponding menus.
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
bool "Dialog Semiconductor DA9030/DA9034 PMIC Support"
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.
