| 2 | ======================== |
| 3 | |
| 4 | Supported chips: |
| 5 | * APM X-Gene SoC |
| 6 | |
| 7 | Description |
| 8 | ----------- |
| 9 | |
| 10 | This driver adds hardware temperature and power reading support for |
| 11 | APM X-Gene SoC using the mailbox communication interface. |
| 12 | For device tree, it is the standard DT mailbox. |
| 13 | For ACPI, it is the PCC mailbox. |
| 14 | |
| 15 | The following sensors are supported |
| 16 | |
| 17 | * Temperature |
| 18 | - SoC on-die temperature in milli-degree C |
| 19 | - Alarm when high/over temperature occurs |
| 20 | * Power |
| 21 | - CPU power in uW |
| 22 | - IO power in uW |
| 23 | |
| 24 | sysfs-Interface |
| 25 | --------------- |
| 26 | |
| 27 | temp0_input - SoC on-die temperature (milli-degree C) |
| 28 | temp0_critical_alarm - An 1 would indicates on-die temperature exceeded threshold |
| 29 | power0_input - CPU power in (uW) |
| 30 | power1_input - IO power in (uW) |
