 60Description
 61-----------
 62
 63Chips in this series are multi-phase step-down converters with one or two
 64output channels and up to 8 phases per channel.
 65
 66
 67Usage Notes
 68-----------
 69
 70This driver does not probe for PMBus devices. You will have to instantiate
 71devices explicitly.
 72
 73Example: the following commands will load the driver for an TPS53681 at address
 740x60 on I2C bus #1::
 75
 76	# modprobe tps53679
 77	# echo tps53681 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
