Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The LTC2978 is an octal power supply monitor, supervisor, sequencer and
|
||
|
|
margin controller.

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 LTC2978 at address
|
||
|
|
0x60 on I2C bus #1:
|
||
|
|
|
||
|
|
# modprobe ltc2978
|
||
|
|
# echo ltc2978 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
