+
+Description
+-----------
+
+Chips in this series are multi-phase step-down converters with one or two
+output channels and up to 8 phases per channel.
+
+
+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 TPS53681 at address
+0x60 on I2C bus #1::
+
+ # modprobe tps53679
+ # echo tps53681 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
+
