1 Kernel driver ltc4215 2 ===================== 3 4 Supported chips: 5 * Linear Technology LTC4215 6 Prefix: 'ltc4215' 7 Addresses scanned: 0x44 8 Datasheet: 9 http://www.linear.com/pc/downloadDocument.do?navId=H0,C1,C1003,C1006,C1163,P17572,D12697 10 11 Author: Ira W. Snyder <iws@ovro.caltech.edu> 12 13 14 Description 15 ----------- 16 17 The LTC4215 controller allows a board to be safely inserted and removed 18 from a live backplane. 19 20 21 Usage Notes 22 ----------- 23 24 This driver does not probe for LTC4215 devices, due to the fact that some 25 of the possible addresses are unfriendly to probing. You will have to 26 instantiate the devices explicitly. 27 28 Example: the following will load the driver for an LTC4215 at address 0x44 29 on I2C bus #0: 30 $ modprobe ltc4215 31 $ echo ltc4215 0x44 > /sys/bus/i2c/devices/i2c-0/new_device 32 33 34 Sysfs entries 35 ------------- 36 37 The LTC4215 has built-in limits for overvoltage, undervoltage, and 38 undercurrent warnings. This makes it very likely that the reference 39 circuit will be used. 40 41 in1_input input voltage 42 in2_input output voltage 43 44 in1_min_alarm input undervoltage alarm 45 in1_max_alarm input overvoltage alarm 46 47 curr1_input current 48 curr1_max_alarm overcurrent alarm 49 50 power1_input power usage 51 power1_alarm power bad alarm
