|
A simple common binding for matrix-connected key boards. Currently targeted at
|
|
defining the keys in the scope of linux key codes since that is a stable and
|
|
standardized interface at this time.
|
|
|
|
Some users of this binding might choose to specify secondary keymaps for
|
|
cases where there is a modifier key such as a Fn key. Proposed names
|
|
for said properties are "linux,fn-keymap" or with another descriptive
|
|
word for the modifier other from "Fn".

|
properties:

linux,keymap:

|
|
description: |
|
|
An array of packed 1-cell entries containing the equivalent of row,
|
|
column and linux key-code. The 32-bit big endian cell is packed as:
|
|
row << 24 | column << 16 | key-code

keypad,num-rows:

description: Number of row lines connected to the keypad controller.

|
keypad,num-columns:

|
$ref: /schemas/types.yaml#/definitions/uint32
|
|
description: Number of column lines connected to the keypad controller.
