Snyder <iws@ovro.caltech.edu>17 18 19Description20-----------21 22The LTC4215 controller allows a board to be safely inserted and removed23from a live backplane.24 25 26Usage Notes27-----------28 29This driver does not probe for LTC4215 devices, due to the fact that some30of the possible addresses are unfriendly to probing. You will have to31instantiate the devices explicitly.32 33Example: the following will load the driver for an LTC4215 at address 0x4434on I2C bus #0::35 36 $ modprobe ltc421537 $ echo ltc4215 0x44 > /sys/bus/i2c/devices/i2c-0/new_device38 39 40Sysfs entries41-------------42 43The LTC4215 has built-in limits for overvoltage, undervoltage, and44undercurrent warnings. This makes it very likely that the reference45circuit will be used.46 47======================= =========================48in1_input input voltage49in2_input output voltage50 51in1_min_alarm input undervoltage alarm52in1_max_alarm input overvoltage alarm53 54curr1_input current55curr1_max_alarm overcurrent alarm56 57power1_input power usage58power1_alarm power bad alarm59======================= =========================60
