Description¶
Chips in this series are multi-phase step-down converters with one or twooutput channels and up to 8 phases per channel.
Usage Notes¶
This driver does not probe for PMBus devices. You will have to instantiatedevices explicitly.
Example: the following commands will load the driver for an TPS53681 at address0x60 on I2C bus #1:
# modprobe tps53679# echo tps53681 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
