In order to add meta-schema checks for additional/unevaluatedProperties being present, all schema need to make this explicit. As common/shared schema are included by other schemas, they should always allow for additionalProperties.

description: |
|
|
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:
|
|
$ref: '/schemas/types.yaml#/definitions/uint32-array'
|
|
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:
|
|
$ref: /schemas/types.yaml#/definitions/uint32
|
|
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.

|
|
keypad {
|
