^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) This driver supports hardware monitoring for SoC's based on the ARM
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) System Control Processor (SCP) implementing the System Control
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Processor Interface (SCPI). The following sensor types are supported
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) by the SCP:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) * temperature
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) * voltage
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * current
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * power
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) The SCP interface provides an API to query the available sensors and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) their values which are then exported to userspace by this driver.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) The driver relies on device tree node to indicate the presence of SCPI
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) support in the kernel. See
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) Documentation/devicetree/bindings/arm/arm,scpi.txt for details of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) devicetree node.
