22The LTC4215 controller allows a board to be safely inserted and removed
23from a live backplane.

26Usage Notes
27-----------
28
29This driver does not probe for LTC4215 devices, due to the fact that some
30of the possible addresses are unfriendly to probing. You will have to
31instantiate the devices explicitly.
32
33Example: the following will load the driver for an LTC4215 at address 0x44
34on I2C bus #0::
35
36	$ modprobe ltc4215
37	$ echo ltc4215 0x44 > /sys/bus/i2c/devices/i2c-0/new_device

43The LTC4215 has built-in limits for overvoltage, undervoltage, and
44undercurrent warnings. This makes it very likely that the reference
45circuit will be used.
