Subject: [PATCH v2 0/3] Add support for hashing algorithms in TI DTHE V2

DTHEv2 is a new cryptography engine introduced in TI AM62L SoC. The
features of DTHEv2 were detailed in [1]. Additional hardware details
available in SoC TRM [2]. DTHEv2 includes, among its various
sub-components, a hashing engine which is compliant with various IETF
and NIST standards, including FIPS 180-3 and FIPS PUB 198.

This patch series adds support for the hashing algorithms
SHA224/256/384/512 and MD5 as well as their HMAC counnterparts for the
hashing engine of Texas Instruments DTHE V2 crypto driver.

This patch series depends on the following previous series [3]:
[PATCH v8 0/3] Add support for more AES modes in TI DTHEv2

The driver is tested using full kernel crypto selftests
(CRYPTO_SELFTESTS_FULL) which all pass successfully [4].

Changelog:
v2:
 - Completely revamped the driver to use the new CRYPTO_AHASH_BLOCK_ONLY
   framework for handling partial blocks and crypto_engine for queueing.
 - Added HMAC as well.
