+The BD718x7 supports two different HW states as reset target states. States
+are called as SNVS and READY. At READY state all the PMIC power outputs go
+down and OTP is reload. At the SNVS state all other logic and external
+devices apart from the SNVS power domain are shut off. Please refer to NXP
+i.MX8 documentation for further information regarding SNVS state. When a
+reset is done via SNVS state the PMIC OTP data is not reload. This causes
+power outputs that have been under SW control to stay down when reset has
+switched power state to SNVS. If reset is done via READY state the power
+outputs will be returned to HW control by OTP loading. Thus the reset
+target state is set to READY by default. If SNVS state is used the boot
+crucial regulators must have the regulator-always-on and regulator-boot-on

+This module is part of the MAX77650 MFD device. For more details
+see Documentation/devicetree/bindings/mfd/max77650.txt.
+
+The regulator controller is represented as a sub-node of the PMIC node

+The device has a single LDO regulator and a SIMO buck-boost regulator with
+three independent power rails.
+
+Required properties:
+--------------------
+- compatible: Must be "maxim,max77650-regulator"
+
+Each rail must be instantiated under the regulators subnode of the top PMIC
+node. Up to four regulators can be defined. For standard regulator properties
+refer to Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Available regulator compatible strings are: "ldo", "sbb0", "sbb1", "sbb2".
