Kernel driver sa67mcu¶
Supported chips:
Kontron sa67mcu
Prefix: ‘sa67mcu’
Datasheet: not available
Authors: Michael Walle <mwalle@kernel.org>
Description¶
The sa67mcu is a board management controller which also exposes a hardwaremonitoring controller.
The controller has two voltage and one temperature sensor. The values arehold in two 8 bit registers to form one 16 bit value. Reading the lower bytewill also capture the high byte to make the access atomic. The unit of thevolatge sensors are 1mV and the unit of the temperature sensor is 0.1degC.
Sysfs entries¶
The following attributes are supported.
in0_label | “VDDIN” |
in0_input | Measured VDDIN voltage. |
in1_label | “VDD_RTC” |
in1_input | Measured VDD_RTC voltage. |
temp1_input | MCU temperature. Roughly the board temperature. |
