Subject: [PATCH v3 01/15] dt-bindings: gpio: convert bindings for NXP PCA953x family to dtschema
Date: Wed, 16 Sep 2020 17:57:01 +0200 [thread overview]
Message-ID: <20200916155715.21009-2-krzk@kernel.org> (raw)
In-Reply-To: <20200916155715.21009-1-krzk@kernel.org>
Convert the NXP PCA953x family of GPIO expanders bindings to device tree
schema.
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
Reviewed-by: Rob Herring <robh@kernel.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.
