This adds device tree bindings for the ixp4xx crypto engine. Cc: devicetree@xxxxxxxxxxxxxxx Signed-off-by: Linus Walleij <linus.walleij@xxxxxxxxxx> --- Herbert, David: This can be applied separately once we are happy with the bindings, alternatively it can be merged with the support code into ARM SoC. --- .../bindings/crypto/intel,ixp4xx-crypto.yaml | 59 +++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 Documentation/devicetree/bindings/crypto/intel,ixp4xx-crypto.yaml diff --git a/Documentation/devicetree/bindings/crypto/intel,ixp4xx-crypto.yaml b/Documentation/devicetree/bindings/crypto/intel,ixp4xx-crypto.yaml new file mode 100644 index 000000000000..28d75f4f9a76 --- /dev/null +++ b/Documentation/devicetree/bindings/crypto/intel,ixp4xx-crypto.yaml @@ -0,0 +1,59 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +# Copyright 2018 Linaro Ltd. +%YAML 1.2 +--- +$id: "http://devicetree.org/schemas/crypto/intel,ixp4xx-crypto.yaml#"; +$schema: "http://devicetree.org/meta-schemas/core.yaml#"; + +title: Intel IXP4xx cryptographic engine + +maintainers: + - Linus Walleij <linus.walleij@xxxxxxxxxx> + +description: | + The Intel IXP4xx cryptographic engine makes use of the IXP4xx NPE + (Network Processing Engine).
