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
