Merge "dt-bindings: Add snapshot of RPM SMD devicetree binding"

Qualcomm Technologies, Inc. RPM SMD cooling device

The RPM shared memory(SMD) cooling device, will be used to set

different thermal band level to RPM hardware. When threshold violation

occurs, RPM SMD cooling device sends pre-configured thermal band level

to RPM hardware via SMD.

Required Parameters:

- compatible:

	Usage: required

	Value type: <string>

	Definition: should be "qcom,rpm-smd-cooling-device"

- #cooling-cells:

	Usage: required

	Value type: <integer>

	Definition: Must be 2. This is required by of-thermal and refer the doc

		<devicetree/bindings/thermal/thermal.txt> for more details.

Example:

&rpm_bus {

	rpm_smd_cdev: rpm-smd-cdev {

		compatible = "qcom,rpm-smd-cooling-device";

		#cooling-cells = <2>;

	};

};
