Snyder <iws@ovro.caltech.edu> 12 13 14Description 15----------- 16 17The LTC4215 controller allows a board to be safely inserted and removed 18from a live backplane. 19 20 21Usage Notes 22----------- 23 24This driver does not probe for LTC4215 devices, due to the fact that some 25of the possible addresses are unfriendly to probing. You will have to 26instantiate the devices explicitly. 27 28Example: the following will load the driver for an LTC4215 at address 0x44 29on I2C bus #0: 30$ modprobe ltc4215 31$ echo ltc4215 0x44 > /sys/bus/i2c/devices/i2c-0/new_device 32 33 34Sysfs entries 35------------- 36 37The LTC4215 has built-in limits for overvoltage, undervoltage, and 38undercurrent warnings. This makes it very likely that the reference 39circuit will be used. 40 41in1_input input voltage 42in2_input output voltage 43 44in1_min_alarm input undervoltage alarm 45in1_max_alarm input overvoltage alarm 46 47curr1_input current 48curr1_max_alarm overcurrent alarm 49 50power1_input power usage 51power1_alarm power bad alarm 52
