- * Hotplug detect deferred task
- *
- * Called after level change on hpd GPIO to evaluate (and debounce) what event
- * has occurred. There are 3 events that occur on HPD:
- * 1. low : downstream display sink is deattached
- * 2. high : downstream display sink is attached
- * 3. irq : downstream display sink signalling an interrupt.
- *
- * The debounce times for these various events are:
- * HPD_USTREAM_DEBOUNCE_LVL : min pulse width of level value.
- * HPD_USTREAM_DEBOUNCE_IRQ : min pulse width of IRQ low pulse.
- *
- * lvl(n-2) lvl(n-1) lvl prev_delta now_delta event
- * ----------------------------------------------------
- * 1 0 1 <IRQ n/a low glitch (ignore)
- * 1 0 1 >IRQ <LVL irq
- * x 0 1 n/a >LVL high
- * 0 1 0 <LVL n/a high glitch (ignore)
