*HT16K33 keyscan driver*

Type: ``bool``

Help
====

Enable keyscan driver for HT16K33.

The HT16K33 is a memory mapping, multifunction LED
controller driver. The controller supports matrix key scan
circuit of up to 13x3 keys.

The keyscan functionality is exposed as up to 3 GPIO
controller drivers, each supporting GPIO callbacks for
keyscan event notifications.
