29 This driver does not probe for LTC4215 devices
30 of the possible addresses are unfriendly to pr
31 instantiate the devices explicitly.
32
33 Example: the following will load the driver fo
34 on I2C bus #0::
35
36 $ modprobe ltc4215
37 $ echo ltc4215 0x44 > /sys/bus/i2c/dev

43 The LTC4215 has built-in limits for overvoltag
44 undercurrent warnings. This makes it very like
45 circuit will be used.
