Signed-off-by: Chris Packham Reviewed-by: Krzysztof Kozlowski --- Notes: Changes in v3: - fix schema id to match filename Changes in v2: - use filename that matches the compatible - put maintainers after title - remove unnecessary label in example - Rework description to focus on what is implemented rather than what may be implemented in the future. .../bindings/mfd/realtek,rtl9302c-switch.yaml | 50 +++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/realtek,rtl9302c-switch.yaml diff --git a/Documentation/devicetree/bindings/mfd/realtek,rtl9302c-switch.yaml b/Documentation/devicetree/bindings/mfd/realtek,rtl9302c-switch.yaml new file mode 100644 index 000000000000..2d20dd07a7e9 --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/realtek,rtl9302c-switch.yaml @@ -0,0 +1,50 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/mfd/realtek,rtl9302c-switch.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Realtek Switch with Internal CPU + +maintainers: + - Chris Packham + +description: + The RTL9302 is an Ethernet switch with an integrated CPU.
