837 VIA VX855/VX875 south bridge. You will need to enable the vx855_spi
838 and/or vx855_gpio drivers for this to do anything useful.
840 config MFD_WL1273_CORE
841 tristate "Support for TI WL1273 FM radio."
846 This is the core driver for the TI WL1273 FM radio. This MFD
847 driver connects the radio-wl1273 V4L2 module and the wl1273
850 config MFD_OMAP_USB_HOST
851 bool "Support OMAP USBHS core driver"
852 depends on USB_EHCI_HCD_OMAP || USB_OHCI_HCD_OMAP3
855 This is the core driver for the OAMP EHCI and OHCI drivers.
856 This MFD driver does the required setup functionalities for
857 OMAP USB Host drivers.
862 config MFD_PM8921_CORE
863 tristate "Qualcomm PM8921 PMIC chip"
868 If you say yes to this option, support will be included for the
869 built-in PM8921 PMIC chip.
871 This is required if your board has a PM8921 and uses its features,
872 such as: MPPs, GPIOs, regulators, interrupts, and PWM.
874 Say M here if you want to include support for PM8921 chip as a module.
875 This will build a module called "pm8921-core".
877 config MFD_PM8XXX_IRQ
878 bool "Support for Qualcomm PM8xxx IRQ features"
879 depends on MFD_PM8XXX
880 default y if MFD_PM8XXX
882 This is the IRQ driver for Qualcomm PM 8xxx PMIC chips.
884 This is required to use certain other PM 8xxx features, such as GPIO

892 depends on I2C=y && GENERIC_HARDIRQS
896 If you say yes here you get support for the TPS65090 series of
897 Power Management chips.
898 This driver provides common support for accessing the device,
899 additional drivers must be enabled in order to use the
900 functionality of the device.
902 config MFD_AAT2870_CORE
903 bool "Support for the AnalogicTech AAT2870"
905 depends on I2C=y && GPIOLIB
907 If you say yes here you get support for the AAT2870.
908 This driver provides common support for accessing the device,
909 additional drivers must be enabled in order to use the
910 functionality of the device.

913 bool "Support for Intel MSIC"
914 depends on INTEL_SCU_IPC
917 Select this option to enable access to Intel MSIC (Avatele
918 Passage) chip. This chip embeds audio, battery, GPIO, etc.
919 devices used in Intel Medfield platforms.
922 bool "Ricoh RC5T583 Power Management system device"
923 depends on I2C=y && GENERIC_HARDIRQS
927 Select this option to get support for the RICOH583 Power
928 Management system device.
929 This driver provides common support for accessing the device
930 through i2c interface. The device supports multiple sub-devices
931 like GPIO, interrupts, RTC, LDO and DCDC regulators, onkey.
932 Additional drivers must be enabled in order to use the
933 different functionality of the device.
