Subject: [PATCH v2] dt-bindings: convert cros-ec-keyb.txt to yaml

Convert the binding file cros-ec-keyb.txt to yaml format.

This was tested and verified on ARM and ARM64 with:

make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/input/cros-ec-keyb.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/input/cros-ec-keyb.yaml

Signed-off-by: Dafna Hirschfeld <[email protected]>

Changes from v1:
add: "additionalProperties: false"

-ChromeOS EC Keyboard

-Google's ChromeOS EC Keyboard is a simple matrix keyboard implemented on

-This binding is based on matrix-keymap.txt and extends/modifies it as follows:

-Required properties:

-
-Optional properties:

Again, should be a Google/Cros person (I'm assuming Dmitry is here as

matrix-keypad.txt should be converted to yaml and then referenced here.

Unless you have max sizes, then there's not any more to add here.

There is no "matrix-keypad.txt" did you mean "matrix-keymap.txt" ?
I see that matrix-keymap.txt is mentioned in 14 files so this will require also
changing all those files.

In include/linux/input/matrix_keypad.h there are the defines
MATRIX_MAX_COLS, MATRIX_MAX_ROWS as 32.
which seems to be the max values
