- 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
