[PATCH v2 0/7] Support of HASH on STM32MP13

[Thomas BOURGOIN]

From: Thomas Bourgoin <thomas.bourgoin@foss.st.com>

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
       Cc: stable@vger.kernel.org and
       Reviewed-by: Linus Walleij <linus.walleij@linaro.org>

[PATCH v2 3/7] crypto: stm32 - remove bufcnt in stm32_hash_write_ctrl.

[Thomas BOURGOIN]

From: Thomas Bourgoin <thomas.bourgoin@foss.st.com>

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.

[PATCH v2 4/7] crypto: stm32 - fix loop iterating through scatterlist for DMA

[Thomas BOURGOIN]

From: Thomas Bourgoin <thomas.bourgoin@foss.st.com>

We were reading the length of the scatterlist sg after copying value of
tsg inside.
So we are using the size of the previous scatterlist and for the first
one we are using an unitialised value.
Fix this by copying tsg in sg[0] before reading the size.

[PATCH v2 5/7] crypto: stm32 - check request size and scatterlist size when using DMA.

[Thomas BOURGOIN]

From: Thomas Bourgoin <thomas.bourgoin@foss.st.com>

When we are sending the data to HASH with the DMA, we send all the data
provided in the scatterlists of the request.
But in some cases (ex : tcrypt performances tests), we should only send
req->nbytes
When iterating through the scatterlist we verify if it is the last
scatterlist or if the number of bytes sent plus the data of the current
scatterlist is superior of the total number of bytes to hash.

[PATCH v2 7/7] crypto: stm32 - remove flag HASH_FLAGS_DMA_READY

[Thomas BOURGOIN]

From: Thomas Bourgoin <thomas.bourgoin@foss.st.com>

Remove flag HASH_FLAGS_DMA_READY as it can put the driver in a deadlock
state.
If the DMA automatically set the DCAL bit, the interrupt indicating the
end of a computation can be raised before the DMA complete sequence.
