                       Valid range is from 100ms to 1000ms. This property determines how often
                       the driver collects timestamp data. If this property is not specified,

+- nvpps-event-mode-init: Optional property that specifies the initial operating mode of the NvPPS driver.
+                         Valid values are 1 (GPIO mode) and 2 (TIMER mode). If this property is not
+                         specified, the default mode is determined based on the presence of the
+                         nvpps-gpios property - GPIO mode becomes the default when nvpps-gpios is
+                         specified, otherwise TIMER mode is used as the default.
 
 Example: Timer mode on Orin.
