15-----------
16
17The LTC4215 controller allows a board to be safely inserted and removed
18from a live backplane.

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 need to use
26the "force" parameter to tell the driver where to find the device.
27
28Example: the following will load the driver for an LTC4215 at address 0x44
29on I2C bus #0:
30$ modprobe ltc4215 force=0,0x44

36The LTC4215 has built-in limits for overvoltage, undervoltage, and
37undercurrent warnings. This makes it very likely that the reference
38circuit will be used.
