dt-bindings: Add snapshot of CX Ipeak cooling device devicetree binding 

Add snapshot of CX Ipeak devicetree binding to the devicetree project.
This snapshot is taken as of 'commit <829fee7bd3d86> ("driver:
thermal: Update CX Ipeak driver to support CX Ipeak v1.1 hardware")'
of the msm-4.14 kernel project.

Qualcomm Technologies, Inc. CX Peak current cooling device



The CX IPEAK cooling device, will be used to set thermal client vote to

CX IPEAK  LM hardware. When all pre-defined clients on CX rail including

thermal client set their vote, CXIP LM hardware throttles pre-defined

client on the same rail.



Required Parameters:

- compatible:

	Usage: required

	Value type: <string>

	Definition: should be "qcom,cxip-lm-cooling-device"



- reg:

	Usage: required

	Value type: <values in hex>

	Definition: Must contain 2 variables <a b> where 'a' is the starting

		register address of the CX IPEAK LM hardware and 'b' is the

		size of the peripheral address space.



- qcom,thermal-client-offset:

	Usage: Optional

	Value type: <value in hex>

	Definition: This property is required for CX IP LM v1.1 and above

		hardware. Must contain offset from CX IPEAK LM reg

		base for thermal client voting. If this property is not defined,

		then CX IPEAK cooling device will use legacy CXIP LM hardware

		offset registers.



- qcom,bypass-client-list:

	Usage: Optional

	Value type: <value in hex>

	Definition: This property is required for CX IP LM v1.1 and above

		hardware. Must contain array of offsets from CX IPEAK LM reg

		base for clients those are not participating voting to CXIP LM

		hardware. This property makes sense only when thermal-client

		is defined.



- #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:



	cxip_cdev: cxip-cdev@1fed000 {

		compatible = "qcom,cxip-lm-cooling-device";

		reg = <0x1fed000 0x24>;

		qcom,thermal-client-offset = <0x8000>;

		qcom,bypass-client-list = <0x2004 0x3004>;

		#cooling-cells = <2>;

	};
