From: Thomas Bourgoin <[email protected]>
The STM32MP13 platform introduces a new version of the IP HASH.
This version of the IP support SHA1, SHA2, SHA3 algorithms and HMAC.
This serie also add some fixes when using the DMA to feed data to the IP.
1. Add new YAML compatible st,stm32mp13-hash.
2. Update driver to support SHA2, SHA3 algorithms for the compatible
st,stm32mp13-hash.
3. Argument bufcnt is unused in function stm32_hash_write_ctrl. Removes it
to simplify the declaration of the function.
4-7. DMA fixes
Changes in v2:
- Add SoB in dt-bindings: crypto: add new compatible for stm32-hash
- Fix regression in crypto: stm32 - add new algorithms support
The macro HASH_CSR_NB_SHA256 was equal to 22 change to 38.
- Update commit message of crypto: stm32 - fix MDMAT condition

From: Thomas Bourgoin <[email protected]>
Commit "crypto: stm32 - Fix empty message processing" remove the use of
the argument bufcnt in stm32_hash_write_ctrl.
Hence, we can remove it from the function prototype and simplify the
function declaration.
