+Description
+-----------
+
+IR35215 is a Dual Output Digital Multi-Phase Controller
+
+
+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 IR35215
+at address 0x40 on I2C bus #4:
+
+# modprobe ir35215
+# echo ir35215 0x40 > /sys/bus/i2c/devices/i2c-4/new_device
+
