From: Alice Guo <alice.guo@xxxxxxx> Add DT Binding doc for the Unique ID of i.MX 8M series. Signed-off-by: Alice Guo <alice.guo@xxxxxxx> --- Changes for v8: - match soc node with regular expression Changes for v7: - change to a separate schema file Changes for v6: - none Changes for v5: - correct the error of using allOf Changes for v4: - use allOf to limit new version DTS files for i.MX8M to include "fsl,imx8m*-soc", nvmem-cells and nvmem-cells-names Changes for v3: - put it into Documentation/devicetree/bindings/arm/fsl.yaml - modify the description of nvmem-cells - use "make ARCH=arm64 dtbs_check" to make sure it is right Changes for v2: - remove the subject prefix "LF-2571-1" .../bindings/soc/imx/imx8m-soc.yaml | 54 +++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 Documentation/devicetree/bindings/soc/imx/imx8m-soc.yaml diff --git a/Documentation/devicetree/bindings/soc/imx/imx8m-soc.yaml b/Documentation/devicetree/bindings/soc/imx/imx8m-soc.yaml new file mode 100644 index 000000000000..f0b0fc7b3ac6 --- /dev/null +++ b/Documentation/devicetree/bindings/soc/imx/imx8m-soc.yaml @@ -0,0 +1,54 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/soc/imx/imx8m-soc.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: NXP i.MX8M Series SoC + +maintainers: + - Alice Guo <alice.guo@xxxxxxx> + +description: | + NXP i.MX8M series SoCs contain fuse entries from which SoC Unique ID can be + obtained. + +select: + properties: + compatible: + contains: + enum: + - fsl,imx8mm + - fsl,imx8mn + - fsl,imx8mp + - fsl,imx8mq + required: + - compatible + +patternProperties: + "^soc@[0-9a-f]+$": + type: object + properties: + compatible: + items: + - enum: + - fsl,imx8mm-soc + - fsl,imx8mn-soc + - fsl,imx8mp-soc + - fsl,imx8mq-soc + - const: simple-bus + + nvmem-cells: + maxItems: 1 + description: Phandle to the SOC Unique ID provided by a nvmem node + + nvmem-cells-names: + const: soc_unique_id + + required: + - compatible + - nvmem-cells + - nvmem-cell-names + +additionalProperties: true +... -- 2.17.1
