| 8 | Description |
| 9 | ----------- |
| 10 | |
| 11 | This driver adds hardware temperature and power reading support for |
| 12 | APM X-Gene SoC using the mailbox communication interface. |
| 13 | For device tree, it is the standard DT mailbox. |
| 14 | For ACPI, it is the PCC mailbox. |
| 15 | |
| 16 | The following sensors are supported |
| 17 | |
| 18 | * Temperature |
| Mauro Carvalho Chehab | b04f2f7 | 2019-04-17 06:46:28 -0300 | [diff] [blame] | 19 | - SoC on-die temperature in milli-degree C |
| 20 | - Alarm when high/over temperature occurs |
| 21 | |
