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. |

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 |
