Subject: [PATCH v3 01/15] dt-bindings: gpio: convert bindings for NXP PCA953x family to dtschema

Convert the NXP PCA953x family of GPIO expanders bindings to device tree
schema.

Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>
Reviewed-by: Rob Herring <robh@...nel.org>

Changes since v2:
1. Add Rob's review tag

Changes since v1:
1. Use additionalProperties.
2. Add wakeup-source.
3. Add hogs.
4. Extend example with hogs.
