Kernel driver ltc4215
=====================
Supported chips:
* Linear Technology LTC4215
Prefix: 'ltc4215'
Addresses scanned: 0x44
Datasheet:
http://www.linear.com/pc/downloadDocument.do?navId=H0,C1,C1003,C1006,C1163,P17572,D12697
Author: Ira W. Snyder <iws@ovro.caltech.edu>
Description
-----------
The LTC4215 controller allows a board to be safely inserted and removed
from a live backplane.
Usage Notes
-----------
This driver does not probe for LTC4215 devices, due to the fact that some
of the possible addresses are unfriendly to probing. You will have to
instantiate the devices explicitly.
Example: the following will load the driver for an LTC4215 at address 0x44
on I2C bus #0:
$ modprobe ltc4215
$ echo ltc4215 0x44 > /sys/bus/i2c/devices/i2c-0/new_device
Sysfs entries
-------------
The LTC4215 has built-in limits for overvoltage, undervoltage, and
undercurrent warnings. This makes it very likely that the reference
circuit will be used.
in1_input input voltage
in2_input output voltage
in1_min_alarm input undervoltage alarm
in1_max_alarm input overvoltage alarm
curr1_input current
curr1_max_alarm overcurrent alarm
power1_input power usage
power1_alarm power bad alarm
