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