-- A [KSCAN driver](https://docs.zephyrproject.org/2.3.0/reference/peripherals/kscan.html), which uses `compatible="zmk,kscan-gpio-matrix"` for GPIO matrix based keyboards, or uses `compatible="zmk,kscan-gpio-direct"` for small direct wires.

 - An optional matrix transform, which defines how the KSCAN row/column events are translated into logical "key positions". This is required for non-rectangular keyboards/matrices, where the key positions don't naturally follow the row/columns from the GPIO matrix.
 - A keymap, which binds each key position to a behavior, e.g. key press, mod-tap, momentary layer, in a set of layers.
