[PATCH v2 00/10] SAMA7D65 Add support for Crypto, CAN and PWM

[PATCH v2 00/10] 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.

Changes v1 -> v2:
- Clean up formatting issues in the device tree and DT bindings.
- Add a description of the capabilities for the cyrpto IPs for this SoC.

[PATCH v2 01/10] dt-bindings: crypto: add sama7d65 in Atmel AES

[Ryan.Wanner]

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

Add DT bindings for SAMA7D65 SoC in atmel AES.

The SAMA7D65 similar to the SAM9x75 SoC supports HMAC, dual buffer, and
GCM. And similar all 3 it supports CBC, CFB, CTR, ECB, and XTS.

[PATCH v2 02/10] dt-bindings: crypto: add sama7d65 in Atmel SHA

[Ryan.Wanner]

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

Add DT bindings for SAMA7D65 SoC Atmel SHA.

The SAMA7D65 similar to the SAM9x75 SoC supports SHA1/224/256/384/512
and supports HMAC for the same hashes. They both also support automatic
padding as well as double buffering.
