+- fsl,pmic-stby-poweroff: if present, configure the PMIC to shutdown all
+  power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
+  Use this option if the SoC should be powered off by external power
+  management IC (PMIC) on PMIC_STBY_REQ signal.
+  As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
