Kernel driver xgene-hwmon
========================
Supported chips:
* APM X-Gene SoC
Description
-----------
This driver adds hardware temperature and power reading support for
APM X-Gene SoC using the mailbox communication interface.
For device tree, it is the standard DT mailbox.
For ACPI, it is the PCC mailbox.
The following sensors are supported
* Temperature
- SoC on-die temperature in milli-degree C
- Alarm when high/over temperature occurs
* Power
- CPU power in uW
- IO power in uW
sysfs-Interface
---------------
temp0_input - SoC on-die temperature (milli-degree C)
temp0_critical_alarm - An 1 would indicates on-die temperature exceeded threshold
power0_input - CPU power in (uW)
power1_input - IO power in (uW)
