config I2C
	tristate "I2C support"
	---help---
	  I2C (pronounce: I-square-C) is a slow serial bus protocol used in
	  many micro controller applications and developed by Philips.  SMBus,
	  or System Management Bus is a subset of the I2C protocol.  More
	  information is contained in the directory <file:Documentation/i2c/>,
	  especially in the file called "summary" there.

	  Both I2C and SMBus are supported here. You will need this for
	  hardware sensors support, and also for Video For Linux support.

	  If you want I2C support, you should say Y here and also to the
	  specific driver for your bus adapter(s) below.

	  This I2C support can also be built as a module.  If so, the module
	  will be called i2c-core.

config I2C_BOARDINFO
	boolean
	depends on I2C
	default y

config I2C_CHARDEV
	tristate "I2C device interface"
	depends on I2C
	help
	  Say Y here to use i2c-* device files, usually found in the /dev
	  directory on your system.  They make it possible to have user-space
	  programs use the I2C bus.  Information on how to do this is
	  contained in the file <file:Documentation/i2c/dev-interface>.

	  This support is also available as a module.  If so, the module 
	  will be called i2c-dev.

config I2C_DEBUG_CORE
	bool "I2C Core debugging messages"
	depends on I2C
	help
	  Say Y here if you want the I2C core to produce a bunch of debug
	  messages to the system log.  Select this if you are having a
	  problem with I2C support and want to see more of what is going on.

config I2C_DEBUG_ALGO
	bool "I2C Algorithm debugging messages"
	depends on I2C
	help
	  Say Y here if you want the I2C algorithm drivers to produce a bunch
	  of debug messages to the system log.  Select this if you are having
	  a problem with I2C support and want to see more of what is going
	  on.

config I2C_DEBUG_BUS
	bool "I2C Bus debugging messages"
	depends on I2C
	help
	  Say Y here if you want the I2C bus drivers to produce a bunch of
	  debug messages to the system log.  Select this if you are having
	  a problem with I2C support and want to see more of what is going
	  on.

config I2C_DEBUG_CHIP
	bool "I2C Chip debugging messages"
	depends on I2C
	help
	  Say Y here if you want the I2C chip drivers to produce a bunch of
	  debug messages to the system log.  Select this if you are having
	  a problem with I2C support and want to see more of what is going
	  on.
