Author: Guenter Roeck <linux@roeck-us.net>

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
