-Qualcomm PON Device
-
-The Power On device for Qualcomm PM8xxx is MFD supporting pwrkey
-and resin along with the Android reboot-mode.
-
-This DT node has pwrkey and resin as sub nodes.
-
-Required Properties:
--compatible: Must be one of:
-	"qcom,pm8916-pon"
-	"qcom,pms405-pon"
-	"qcom,pm8998-pon"
-
--reg: Specifies the physical address of the pon register
-
-Optional subnode:
--pwrkey: Specifies the subnode pwrkey and should follow the
- qcom,pm8941-pwrkey.txt description.
--resin: Specifies the subnode resin and should follow the
- qcom,pm8xxx-pwrkey.txt description.
-
-The rest of the properties should follow the generic reboot-mode description
-found in reboot-mode.txt
-
-Example:
-
-	pon@800 {
-		compatible = "qcom,pm8916-pon";
-
-		reg = <0x800>;
-		mode-bootloader = <0x2>;
-		mode-recovery = <0x1>;
-
-		pwrkey {
-			compatible = "qcom,pm8941-pwrkey";
-			interrupts = <0x0 0x8 0 IRQ_TYPE_EDGE_BOTH>;
-			debounce = <15625>;
-			bias-pull-up;
-			linux,code = <KEY_POWER>;
-		};
-
-		resin {
-			compatible = "qcom,pm8941-resin";
-			interrupts = <0x0 0x8 1 IRQ_TYPE_EDGE_BOTH>;
-			debounce = <15625>;
-			bias-pull-up;
-			linux,code = <KEY_VOLUMEDOWN>;
