Add a schema for the NVMEM layout on Kontron's sl28 boards. Signed-off-by: Michael Walle <michael@xxxxxxxx> --- changes since v1: - add custom select - add description - add "additionalProperties: false", I wasn't sure if all the subnodes needs it. I'd say yes, but the brcm,nvram binding doesn't have them neither. .../nvmem/layouts/kontron,sl28-vpd.yaml | 67 +++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 Documentation/devicetree/bindings/nvmem/layouts/kontron,sl28-vpd.yaml diff --git a/Documentation/devicetree/bindings/nvmem/layouts/kontron,sl28-vpd.yaml b/Documentation/devicetree/bindings/nvmem/layouts/kontron,sl28-vpd.yaml new file mode 100644 index 000000000000..0c180f29e880 --- /dev/null +++ b/Documentation/devicetree/bindings/nvmem/layouts/kontron,sl28-vpd.yaml @@ -0,0 +1,67 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/nvmem/layouts/kontron,sl28-vpd.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: NVMEM layout of the Kontron SMARC-sAL28 vital product data + +maintainers: + - Michael Walle <michael@xxxxxxxx> + +description: + The vital product data (VPD) of the sl28 boards contains a serial + number and a base MAC address.
