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) |
