crypto: drivers - Explicitly include correct DT includes

2023-08-23T03:04:23+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

crypto: jh7110 - Use new crypto_engine_op interface

2023-08-18T09:01:11+00:00

Use the new crypto_engine_op interface where the callback is stored
in the algorithm object.

crypto: jh7110 - Include scatterwalk.h for struct scatter_walk

2023-08-18T09:01:10+00:00

Include crypto/scatterwalk.h explicitly instead of getting it
through random header files.

crypto: jh7110 - Include crypto/hash.h in header file

2023-08-18T09:01:10+00:00

The header file jh7110-cryp uses ahash_request without including
crypto/hash.h.  Fix that by adding the inclusion.

crypto: jh1100 - Remove prepare/unprepare request

2023-08-18T09:01:09+00:00

The callbacks for prepare and unprepare request in crypto_engine
is superfluous.  They can be done directly from do_one_request.

Move the code into do_one_request and remove the unused callbacks.

crypto: starfive - fix return value check in starfive_aes_prepare_req()

2023-08-11T11:19:27+00:00

kzalloc() returns NULL pointer not PTR_ERR() when it fails,
so replace the IS_ERR() check with NULL pointer check.

crypto: starfive - Add AES skcipher and aead support

2023-07-28T10:20:25+00:00

Adding AES skcipher and aead support to Starfive crypto module.
Skcipher modes of operation include ecb, cbc, ctr, ofb, cfb. Aead modes
include ccm and gcm.

v1->v2:
- Add include interrupt.h to fix compile error. (Herbert)

crypto: starfive - Convert to platform remove callback returning void

2023-07-20T10:16:25+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

crypto: starfive - Add RSA algo support

2023-06-23T08:15:36+00:00

Adding RSA enc/dec and sign/verify feature for StarFive cryptographic
module. The module only supports mod sizes up to 2048, therefore
calculations more than that will use fallback algo.

crypto: starfive - Update hash module irq handling

2023-06-23T08:15:36+00:00

Hash driver needs to check the value of irq mask register before writing
as it will mask irq of other modules.
