| Description | |
| ----------- | |
| The LTC4215 controller allows a board to be safely inserted and removed | |
| from a live backplane. | |
| Usage Notes | |
| ----------- | |
| This driver does not probe for LTC4215 devices, due to the fact that some | |
| of the possible addresses are unfriendly to probing. You will have to | |
| instantiate the devices explicitly. | |
| Example: the following will load the driver for an LTC4215 at address 0x44 | |
| on I2C bus #0: | |
| $ modprobe ltc4215 | |
| $ echo ltc4215 0x44 > /sys/bus/i2c/devices/i2c-0/new_device | |
| Sysfs entries | |
| ------------- | |
| The LTC4215 has built-in limits for overvoltage, undervoltage, and | |
| undercurrent warnings. This makes it very likely that the reference | |
| circuit will be used. | |
