Subject: [PATCH v5 0/2] STM32 CRYP crypto driver

This set of patches adds a new crypto driver for STMicroelectronics stm32 HW.
This drivers uses the crypto API and provides with HW-enabled block cipher
algorithms.

This driver was successfully tested with tcrypt / testmgr.

Changes since v5:
-add timeout in wait_busy function
-clear key after use
-misc : remove unused functions, use -Exx, use dev_err

Changes since v4:
- remove AEAD support from crypto engine as proposed by Herbert : waiting for
the crypto_engine interface clean up before
[https://www.mail-archive.com/[email protected]/msg1474434.html]
- remove AES GCM & CCM algorithms

Changes since v3:
- update dt-bindings with Rob Herring remarks

Changes since v2:
- update dt-bindings (interrupts description)
- rebase on STM32 crypto patches (L. Debieve : update CRC32 + add HASH)
