* Automatic detection of external audio input/output via the 3.5mm jack
does not currently work.
* Touchpad interrupt non-functional when correctly configured as active-low
and level-triggered, so configured as active-high instead. This causes an
interrupt storm and prevents the CPU from idling due to moderate (10-20%)
usage on a single core.
* PL1/PL2 limited to 15W/20W by charger and battery discharge capability,
not SoC or thermal design.
