Document the linux,keycodes property that enables those keys and specifies the keycodes that should be used to report the key events. Signed-off-by: Nikita Travkin <nikita@...n.ru> --- Changes in v2: - Include input.yaml schema at the top level instead of at the property. (Seems like I still can't think of the schema as device and not implementation-specific thing...) - Reword the description to be more informative. --- .../bindings/input/touchscreen/zinitix,bt400.yaml | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/Documentation/devicetree/bindings/input/touchscreen/zinitix,bt400.yaml b/Documentation/devicetree/bindings/input/touchscreen/zinitix,bt400.yaml index b4e5ba7c0b49..67ed853289b2 100644 --- a/Documentation/devicetree/bindings/input/touchscreen/zinitix,bt400.yaml +++ b/Documentation/devicetree/bindings/input/touchscreen/zinitix,bt400.yaml @@ -16,6 +16,7 @@ maintainers: allOf: - $ref: touchscreen.yaml# + - $ref: ../input.yaml# properties: $nodename: @@ -79,6 +80,15 @@ properties: $ref: /schemas/types.yaml#/definitions/uint32 enum: [1, 2] + linux,keycodes: + description: | + This property specifies an array of keycodes assigned to the + touch-keys that can be present in some touchscreen configurations. + If the touch-keys are enabled, controller firmware will assign some + touch sense lines to those keys. + minItems: 1 + maxItems: 8 + touchscreen-size-x: true touchscreen-size-y: true touchscreen-fuzz-x: true -- 2.30.2
