* For the NXP RW61x, the devicetree property ``exit-latency-us`` has been updated to reflect more
accurate, measured wake-up times. For applications utilizing Standby mode (PM3), this update and
an increase to the ``min-residency-us`` devicetree property may influence how the system
transitions between power modes. In some cases, this could lead to changes in power consumption.
