	  If you say yes here you get support for the Philips ISP1301
	  transceiver working with the OMAP SYNOPSYS controller.
	  The ISP1301 is used in products including H2 and H3 development
	  boards for Texas Instruments OMAP processors.

	  This driver can also be built as a module.  If so, the module
	  will be called isp1301_omap.

# NOTE:  This isn't really OMAP-specific, except for the current
# interface location in  <include/asm-arm/arch-omap/tps65010.h>
# and having mostly OMAP-specific board support
config TPS65010
	tristate "TPS6501x Power Management chips"

	default y if MACH_OMAP_H2 || MACH_OMAP_H3 || MACH_OMAP_OSK
	help
	  If you say yes here you get support for the TPS6501x series of
	  Power Management chips.  These include voltage regulators,
	  lithium ion/polymer battery charging, and other features that
	  are often used in portable devices like cell phones and cameras.

	  This driver can also be built as a module.  If so, the module
	  will be called tps65010.

config SENSORS_TLV320AIC23
	tristate "Texas Instruments TLV320AIC23 Codec"
	depends on I2C && I2C_OMAP
	help
	  If you say yes here you get support for the I2C control
	  interface for Texas Instruments TLV320AIC23 audio codec.

config GPIOEXPANDER_OMAP
	bool "GPIO Expander PCF8574PWR for OMAP"
	depends on I2C && (ARCH_OMAP16XX || ARCH_OMAP24XX)
	help
	  If you say yes here you get support for I/O expander calls

        depends on TWL4030_CORE
        default "26"
        help
          The TWL4030 interrupt service routine must read TWL4030 registers via
          the I2C bus.  The I2C driver can't be invoked from interrupt context,
          so the TWL4030 driver must use a kernel thread to complete the
          servicing of interrupts.  This option selects the scheduling priority
          of the kernel thread.

config TWL4030_GPIO
	bool "TWL4030 GPIO Driver"

	depends on PPC32
	help
	  If you say yes here you get support for the ST M41T00 RTC chip.

	  This driver can also be built as a module.  If so, the module
	  will be called m41t00.

	tristate "Maxim MAX6875 Power supply supervisor"
	depends on EXPERIMENTAL
	help
	  If you say yes here you get support for the Maxim MAX6875
	  EEPROM-programmable, quad power-supply sequencer/supervisor.
