Description
-----------

LTC3815 is a Monolithic Synchronous DC/DC Step-Down Converter.


Usage Notes
-----------

This driver does not probe for PMBus devices. You will have to instantiate
devices explicitly.

Example: the following commands will load the driver for an LTC3815
at address 0x20 on I2C bus #1::

	# modprobe ltc3815
	# echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device
