PFUZE100 family of regulators
Required properties:
-- compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000"
+- compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000", "fsl,pfuze3001"
- reg: I2C slave address
+Optional properties:
+- fsl,pfuze-support-disable-sw: Boolean, if present disable all unused switch
+ regulators to save power consumption. Attention, ensure that all important
+ regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on"
+ property. If not present, the switched regualtors are always on and can't be
+ disabled. This binding is a workaround to keep backward compatibility with
+ old dtb's which rely on the fact that the switched regulators are always on
+ and don't mark them explicit as "regulator-always-on".
