Register Policy Engine recommendations as sensor with thermal framework.
Thermal framework can mitigate cooling devices for the recommendations
from policy engine sensor.

Policy Engine(PE) recommendation as sensor.



The QTI Policy Engine sensor device will register the policy engine

recommendation with thermal framework as a sensor. This will enable

to provide configuration to mitigate cooling devices when a recommendation

is sent from Policy Engine hardware. The recommendations are mitigation

levels based on CX operating level.



There can be multiple Policy Engine hardwares for different rails.



Properties:



- compatible:

	Usage: required

	Value type: <string>

	Definition: should be "qcom,policy-engine"



- reg:

    Usage: required

    Value type: <u32>

    Definition: RDPM_PE base address.



- #thermal-sensor-cells:

	Usage: required

	Value type: <integer>

	Definition: Must be 0. See thermal.txt for description.



- interrupts:

    Usage: required

    Value type: <prop-encoded-array>

    Definition: Policy Engine master interrupt.





Example:



cx_rdpm_pe@0x00635000 {

	compatible = "qcom,policy-engine";

	#thermal-sensor-cells = <0>;

	reg = <0x00635000 0x1000>;

	interrupts = <GIC_SPI 243 IRQ_TYPE_EDGE_RISING>;

};
