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-psy".



- 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.



- io-channels

- io-channel-names

  Usage:      required

  Value type: <phandle>

  Definition: For details about IIO bindings see:

	      Documentation/devicetree/bindings/iio/iio-bindings.txt



================================================

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-psy";

	qcom,pmic-revid = <&smb1390_revid>;

	interrupt-parent = <&smb1390>;

	status = "disabled";



	io-channels = <&pm8150b_vadc ADC_AMUX_THM2>;

	io-channel-names = "cp_die_temp";



	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";

	};
