[PATCH 0/9] SAMA7D65 Add support for Crypto, CAN and PWM

[Ryan.Wanner]

From: Ryan Wanner <Ryan.Wanner@microchip.com>

This set adds support for the SAMA7D65 SoC crypto subsystem and enabling
them in the device tree. This set also adds PWM to the device tree, and
adds and enables the CAN bus system for the SAMA7D65 SoC.

Ryan Wanner (9):
  dt-bindings: crypto: add sama7d65 in Atmel AES
  dt-bindings: crypto: add sama7d65 in Atmel SHA
  dt-bindings: crypto: add sama7d65 in Atmel TDES
  dt-bindings: rng: atmel,at91-trng: add sama7d65 TRNG
  crypto: atmel - add support for AES and SHA IPs available on sama7d65
    SoC
  ARM: dts: microchip: sama7d65: Add crypto support
  ARM: dts: microchip: sama7d65: Add PWM support
  ARM: dts: microchip: sama7d65: Add CAN bus support
  ARM: dts: microchip: sama7d65: Enable CAN bus

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:
./Documentation/devicetree/bindings/crypto/atmel,at91sam9g46-aes.yaml:19:13: [warning] wrong indentation: expected 14 but found 12 (indentation)

dtschema/dtc warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/a5509576e211bcf528e088f78e619575a26bbd8f.1747077616.git.Ryan.Wanner@microchip.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Hi, Ryan,

Would be good to improve the description here, e.g., specify differences,
similarities b/w SAMA7D65 and SAM9X7 or SAM9G46. Same for other similar
patches in this series.

Thank you,
Claudiu
