+Kernel driver ltc3815
+=====================
+
+Supported chips:
+
+ * Linear Technology LTC3815
+
+ Prefix: 'ltc3815'

+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
