Subject: [PATCH v3 0/2] Add support for Texas Instruments DTHE V2 crypto accelerator
This series adds support for TI DTHE V2 crypto accelerator. DTHE V2 is a
new crypto accelerator which contains multiple crypto IPs [1].
This series implements support for ECB and CBC modes of AES for the AES
Engine of the DTHE, using skcipher APIs of the kernel.
Tested with:
CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y
and tcrypt,
sudo modprobe tcrypt mode=500 sec=1

[1]: Section 14.6.3 (DMA Control Registers -> DMASS_DTHE)

Change log:
v3:
- Corrected dt-bindings reg length is too long error
- Converted AES driver code to use crypto_engine APIs for using
internal crypto queue instead of mutex.
- Removed calls to skcipher_request_complete in paths not returning
-EINPROGRESS before.
- Added missing KConfig import, which was accidentally removed in v2.
v2:
- Corrected dt-bindings syntax errors and other review comments in v1.
- Completely changed driver code structure, splitting code into
multiple files
