Kernel driver sfctemp

=====================



Supported chips:

 - StarFive JH7100

 - StarFive JH7110



Authors:

 - Emil Renner Berthing <kernel@esmil.dk>



Description

-----------



This driver adds support for reading the built-in temperature sensor on the

JH7100 and JH7110 RISC-V SoCs by StarFive Technology Co. Ltd.



``sysfs`` interface

-------------------



The temperature sensor can be enabled, disabled and queried via the standard

hwmon interface in sysfs under ``/sys/class/hwmon/hwmonX`` for some value of

``X``:



================ ==== =============================================

Name             Perm Description

================ ==== =============================================

temp1_enable     RW   Enable or disable temperature sensor.

                      Automatically enabled by the driver,

                      but may be disabled to save power.

temp1_input      RO   Temperature reading in milli-degrees Celsius.
