		Qualcomm Technologies, Inc. SMB1390 Charger Specific Bindings

		SMB1390 charge pump is paired with QTI family of standalone chargers to
		enable a high current, high efficiency Li+ battery charging system.

		=======================
		Required Node Structure
		=======================

		SMB1390 Charger must be described in two levels of device nodes.

		==================================
		First Level Node - SMB1390 Charger
		==================================

		Charger specific properties:
		- compatible
		Usage: required
		Value type: <string>
		Definition: "qcom,smb1390-charger".

		- qcom,pmic-revid
		Usage: required
		Value type: phandle
		Definition: Should specify the phandle of SMB's revid module. This is used
		to identify the SMB subtype.

		- qcom,channel-num
		Usage: required
		Value type: <u32>
		Definition: Specifies the ADC channel number for reading die temperature.

		================================================
		Second Level Nodes - SMB1390 Charger Peripherals
		================================================

		Peripheral specific properties:
		- interrupts
		Usage: required
		Value type: <prop-encoded-array>
		Definition: Peripheral interrupt specifier.

		- interrupt-names
		Usage: required
		Value type: <stringlist>
		Definition: Interrupt names. This list must match up 1-to-1 with the
		interrupts specified in the 'interrupts' property.

		=======
		Example
		=======

		smb1390_charger: qcom,charge_pump {
		compatible = "qcom,smb1390-charger";
		qcom,pmic-revid = <&smb1390_revid>;
		qcom,channel-num = <15>
		interrupt-parent = <&smb1390>;
		qcom,smb-vadc = <&pm8998_vadc>;
		status = "disabled";

		qcom,core {
		interrupts = <0x10 0x0 IRQ_TYPE_EDGE_RISING>,
		<0x10 0x1 IRQ_TYPE_EDGE_RISING>,
		<0x10 0x2 IRQ_TYPE_EDGE_RISING>,
		<0x10 0x3 IRQ_TYPE_EDGE_RISING>,
		<0x10 0x4 IRQ_TYPE_EDGE_RISING>;
		interrupt-names = "switcher-off-window",
		"switcher-off-fault",
		"vph-ov-soft",
		"ilim",
		"temp-alarm";
		};
		};
