+ description:
+ Low power to high speed delay time in microseconds.
+ The purpose of this property is force a DPhy reset for the period
+ described by the microseconds on the property, before it starts
+ streaming. To be clear, with that value bigger than 0 the Alvium
+ forces a dphy-reset on all lanes for that period. That means all
+ lanes go up into low power state. This may help a csi2 rx ip to
+ reset if that IP can't deal with a continous clock.
