+- rohm,reset-snvs-powered : Transfer BD718x7 to SNVS state at reset.
+
+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
+properties set in regulator node.
