+This is bus driver for Sandbox. It includes part of emulated pm8916 pmic.

+Required properties:
+- compatible: "sandbox,spmi"
+- #address-cells: 0x1 - childs slave ID address
+- #size-cells: 0x1
+
+Example:
+
+spmi: spmi@0 {
+ compatible = "sandbox,spmi";
+ #address-cells = <0x1>;
+ #size-cells = <0x1>;
+ pm8916@0 {
+ compatible = "qcom,spmi-pmic";
+ reg = <0x0 0x1>;
+ #address-cells = <0x1>;
+ #size-cells = <0x1>;
+
+ spmi_gpios: gpios@c000 {
+ compatible = "qcom,pm8916-gpio";
+ reg = <0xc000 0x400>;
+ gpio-controller;
+ gpio-count = <4>;
