menuconfig I2C
	bool "I2C support"
	default y
	help
	  Note:
	  This is a stand-in for an option to enable I2C support. In fact this
	  simply enables building of the I2C directory for U-Boot. The actual
	  I2C feature is enabled by DM_I2C (for driver model) and
	  the #define CONFIG_SYS_I2C_LEGACY (for the legacy I2C stack).

	  So at present there is no need to ever disable this option.

	  Eventually it will:

	  Enable support for the I2C (Inter-Integrated Circuit) bus in U-Boot.
	  I2C works with a clock and data line which can be driven by a
	  one or more masters or slaves. It is a fairly complex bus but is
	  widely used as it only needs two lines for communication. Speeds of
	  400kbps are typical but up to 3.4Mbps is supported by some
	  hardware. Enable this option to build the drivers in drivers/i2c as
	  part of a U-Boot build.

	  This provides an I2C bus that will tunnel i2c commands through to
	  the other side of the Chrome OS EC to the I2C bus connected there.

	bool "Provide access to LDOs on the Chrome OS EC"

	On many Chromebooks the main PMIC is inaccessible to the AP. This is
	often dealt with by using an I2C pass-through interface provided by
	the EC. On some unfortunate models (e.g. Spring) the pass-through
	is not available, and an LDO message is available instead. This
	option enables a driver which provides very basic access to those
	regulators, via the EC. We implement this as an I2C bus	which
	emulates just the TPS65090 messages we know about. This is done to
	avoid duplicating the logic in the TPS65090 regulator driver for
	enabling/disabling an LDO.

	help
	  Support for Tegra I2C controllers managed by the BPMP (Boot and
	  Power Management Processor). On Tegra186, some I2C controllers are
	  directly controlled by the main CPU, whereas others are controlled
	  by the BPMP, and can only be accessed by the main CPU via IPC
	  requests to the BPMP. This driver covers the latter case.

	  I2C Slave address channel 0 for all buses in the legacy drivers.
	  Many boards/controllers/drivers don't support an I2C slave
	  interface so provide a default slave address for them for use in
	  common code.  A real value for CONFIG_SYS_I2C_SLAVE should be
