This has been used for ages in the kernel device tree for Ux500 but was never documented, so fill in the gap. Cc: devicetree@vger.kernel.org Cc: Lionel Debieve Signed-off-by: Linus Walleij Reviewed-by: Rob Herring --- The relationship to the existing STM32 CRYP block is pretty obvious when looking at the register map. If preferred, I can just extend the STM32 bindings with these extra (generic) properties and compatibles as well. --- .../crypto/stericsson,ux500-cryp.yaml | 67 +++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 Documentation/devicetree/bindings/crypto/stericsson,ux500-cryp.yaml diff --git a/Documentation/devicetree/bindings/crypto/stericsson,ux500-cryp.yaml b/Documentation/devicetree/bindings/crypto/stericsson,ux500-cryp.yaml new file mode 100644 index 000000000000..9653776007a0 --- /dev/null +++ b/Documentation/devicetree/bindings/crypto/stericsson,ux500-cryp.yaml @@ -0,0 +1,67 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/crypto/stericsson,ux500-cryp.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: ST Microelectronics and ST-Ericsson Ux500 CRYP bindings + +description: The Ux500 CRYP block is identical to the one found in + STn8820 introduced in 2007.
