| Description |
| ----------- |
| |
| This driver supports hardware montoring for Analog Devices ADM1275 Hot-Swap |
| Controller and Digital Power Monitor. |
| |
| The ADM1275 is a hot-swap controller that allows a circuit board to be removed |
| from or inserted into a live backplane. It also features current and voltage |
| readback via an integrated 12-bit analog-to-digital converter (ADC), accessed |
| using a PMBus. interface. |
| |
| The driver is a client driver to the core PMBus driver. Please see |
| Documentation/hwmon/pmbus for details on PMBus client drivers. |
| |
| |
| Usage Notes |
| ----------- |
| |
| This driver does not auto-detect devices. You will have to instantiate the |
| devices explicitly. Please see Documentation/i2c/instantiating-devices for |
| details. |
| |
| |
| Platform data support |
| --------------------- |
| |
| The driver supports standard PMBus driver platform data. Please see |
| Documentation/hwmon/pmbus for details. |
