0060 Description
0061 -----------
0062
0063 Chips in this series are multi-phase step-down converters with one or two
0064 output channels and up to 8 phases per channel.
0065
0066
0067 Usage Notes
0068 -----------
0069
0070 This driver does not probe for PMBus devices. You will have to instantiate
0071 devices explicitly.
0072
0073 Example: the following commands will load the driver for an TPS53681 at address
0074 0x60 on I2C bus #1::
0075
0076 # modprobe tps53679
0077 # echo tps53681 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
