PM855B PMIC Simulator



This device simulates the registers found within a Qualcomm Technologies, Inc.

PM855B PMIC chip.



Supported Properties:



- compatible

	Usage:      required

	Value type: <string>

	Definition: Must be "qcom,pm855b-sim".



- qcom,sid-offset

	Usage:      required

	Value type: <u32>

	Definition: Global slave ID (SID) offset of PM855B local SID 0.

		    Supported values: 0 - 14

		    Typical values: 0, 2, or 4



- qcom,spmi-sim

	Usage:      required

	Value type: <phandle>

	Definition: phandle of the spmi-sim bus device that the simulated PMIC

		    device should be used with.



Example:



pm855b-sim {

	compatible = "qcom,pm855b-sim";

	qcom,spmi-sim = <&spmi_sim>;

	qcom,sid-offset = <2>;

};
