The keyboard is connected via GPIOs to the processor, and scanned using a column sample register. The hardware provides no debouncing mechanism, so the state of the keys is read KBDSCAN_STABLE_COUNT times before being reported to the input layer. The status of the keys needs to be polled because there is no interrupt hooked to the lines. A workqueue is used for this.
