+Optional properties:
+- fsl,pmic-stby-poweroff: Configure CCM to assert PMIC_STBY_REQ signal
+  on power off.
+  Use this property if the SoC should be powered off by external power
+  management IC (PMIC) triggered via PMIC_STBY_REQ signal.
+  Boards that are designed to initiate poweroff on PMIC_ON_REQ signal should
+  be using "syscon-poweroff" driver instead.

 The clock consumer should specify the desired clock by having the clock
 ID in its "clocks" phandle cell.  See include/dt-bindings/clock/imx6qdl-clock.h
 for the full list of i.MX6 Quad and DualLite clock IDs.
