| 89 | ----------- |
| 90 | |
Masanari Iida | 92417da | 2016-02-28 12:57:57 +0900 | [diff] [blame] | 91 | This driver supports hardware monitoring for various PMBus compliant devices. |
Guenter Roeck | 44f5a40 | 2010-06-28 14:29:03 -0700 | [diff] [blame] | 92 | It supports voltage, current, power, and temperature sensors as supported |
| 93 | by the device. |
| 94 | |
| 95 | Each monitored channel has its own high and low limits, plus a critical |
| 96 | limit. |
| 97 | |
| 98 | Fan support will be added in a later version of this driver. |
| 99 | |
| 100 | |
| 101 | Usage Notes |
| 102 | ----------- |
| 103 | |
| 104 | This driver does not probe for PMBus devices, since there is no register |
| 105 | which can be safely used to identify the chip (The MFG_ID register is not |
| 106 | supported by all chips), and since there is no well defined address range for |
| 107 | PMBus devices. You will have to instantiate the devices explicitly. |
| 108 | |
| 109 | Example: the following will load the driver for an LTC2978 at address 0x60 |

| 116 | Platform data support |
| 117 | --------------------- |
| 118 | |
| 119 | Support for additional PMBus chips can be added by defining chip parameters in |
| 120 | a new chip specific driver file. For example, (untested) code to add support for |
