In the interest of making long-term branch maintenance incur as little technical debt on us as possible, we should not maintain any files on the branch we are not actually using. This has the added effect of making it extremely clear when merging CLs from the main branch when changes have the possibility to affect us. The follow-on CL adds a convenience script to actually pull updates from the main branch and generate a CL for the update.

- * 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 <LVL irq
- * x 0 1 n/a >LVL high
- * 0 1 0 <LVL n/a high glitch (ignore)
