[PACTH v4 0/3] dt-bindings: crypto: Convert atmel-crypto to YAML

[PACTH v4 0/3] dt-bindings: crypto: Convert atmel-crypto to YAML

[Tudor Ambarus]

Convert Atmel AES, TDES and SHA documentation to yaml format. There is one
binding defined per file. Keeping all bindings under the same yaml does
not make sense, as these are individual IPs. With the conversion the clock
and clock-names properties are made mandatory, to reflect how the drivers
treat them: when these properties are not provided, the drivers return
error.

v4:
- fix the AES example: match the node's address with the reg's address
- collect Krzysztof's R-b tags

v3:
- update license to (GPL-2.0-only OR BSD-2-Clause)
- add "Copyright (C) 2022 Microchip Technology, Inc. and its subsidiaries"
- add Krzysztof's R-b tag on patch 3/3. Chose to keep "maxItems: 1" instead
of "items" and "description" because that's what the guide at [1] suggests:
"# Cases that have only a single entry just need to express that with
maxItems"

[1] https://www.kernel.org/doc/html/latest/devicetree/bindings/writing-schema.html#annotated-example-schema

v2:
- use generic "crypto" node name
- drop redundant status = "okay" - it's the default state anyway
- introduce empty line for readability
- be specific and rename the bindings to let room for future possible
  lines of architectures.

-EINVAL if "aes_clk" is not found, reflect that in the bindings and make

[PACTH v4 3/3] dt-bindings: crypto: Convert Atmel SHA to yaml

[Tudor Ambarus]

Convert Atmel SHA documentation to yaml format. With the conversion the
clock and clock-names properties are made mandatory. The driver returns
-EINVAL if "sha_clk" is not found, reflect that in the bindings and make
the clock and clock-names properties mandatory. Update the example to
better describe how one should define the dt node.
