hwmon: Support sensors exported via ARM SCP interface Create a driver to add support for SoC sensors exported by the System Control Processor (SCP) via the System Control and Power Interface (SCPI). The supported sensor types is one of voltage, temperature, current, and power. The sensor labels and values provided by the SCP are exported via the hwmon sysfs interface.

Description
-----------
This driver supports hardware monitoring for SoC's based on the ARM
System Control Processor (SCP) implementing the System Control
Processor Interface (SCPI). The following sensor types are supported

* temperature
* voltage
* current
* power
The SCP interface provides an API to query the available sensors and
their values which are then exported to userspace by this driver.
Usage Notes
-----------
The driver relies on device tree node to indicate the presence of SCPI
support in the kernel. See
dt-bindings: firmware: update arm,scpi.yaml reference Changeset 1496be719468 ("dt-bindings: firmware: arm,scpi: Convert to json schema") renamed: Documentation/devicetree/bindings/arm/arm,scpi.txt to: Documentation/devicetree/bindings/firmware/arm,scpi.yaml. Update its cross-reference accordingly.
