+Description
+-----------
+
+IR35221 is a Digital DC-DC Multiphase 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 IR35221
+at address 0x70 on I2C bus #4:
+
+# modprobe ir35221
+# echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
