PM855 PMIC Simulator



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

PM855 PMIC chip.



Supported Properties:



- compatible

	Usage:      required

	Value type: <string>

	Definition: Must be "qcom,pm855-sim".



- qcom,sid-offset

	Usage:      required

	Value type: <u32>

	Definition: Global slave ID (SID) offset of PM855 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:



pm855-sim {

	compatible = "qcom,pm855-sim";

	qcom,spmi-sim = <&spmi_sim>;

	qcom,sid-offset = <0>;

};

	  The PM855 PMIC Simulator configures the read/write permissions of all

	  PM855 SPMI registers and loads default register values.  It is used

	  in conjunction with the SPMI Controller Simulator to help test PMIC

	  peripheral drivers before physical PMIC chips are available.
