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 |
