+ * physical unplug (>hdmi_hpd_debounce_delay)
+ * and a spontaneous RX HPD toggle (<hdmi_hpd_debounce_delay).
+ *
+ * If the toggle is less than this delay, the driver compares sink capabilities
+ * and permits a hotplug event if they changed.
+ *
+ * The default value of 1500ms was chosen based on experimental testing with
+ * various monitors that exhibit spontaneous HPD toggling behavior.
