+Driver for part of pm8916 PMIC - gpio and power/reset keys
+
+This device should be child of SPMI pmic.
+
+1) GPIO driver
+
+Required properties:
+- compatible: "qcom,pm8916-gpio"
+- reg: peripheral ID, size of register block
+- gpio-controller
+- gpio-count: number of GPIOs
+- #gpio-cells: 2
+
+Optional properties:
+- gpio-bank-name: name of bank (as default "pm8916" is used)
+
+Example:
+
+pmic_gpios: gpios@c000 {
+	compatible = "qcom,pm8916-gpio";
+	reg = <0xc000 0x400>;
+	gpio-controller;
+	gpio-count = <4>;
+	#gpio-cells = <2>;
+	gpio-bank-name="pmic";
+};
+
+
+2) Power/Reset key driver
+
+Required properties:
+- compatible: "qcom,pm8916-pwrkey"
+- reg: peripheral ID, size of register block
+- gpio-controller
+- #gpio-cells: 2
+
+Optional properties:
+- gpio-bank-name: name of bank (as default "pm8916_key" is used)
+
+
+Example:
+
+pmic_pon: pon@800 {
+	compatible = "qcom,pm8916-pwrkey";
+	reg = <0x800 0x96>;
+	#gpio-cells = <2>;
+	gpio-controller;
+};
