2024-05-10crypto: starfive - Use fallback for unaligned dma accessJia Jie Ho
Dma address mapping fails on unaligned scatterlist offset. Use sw fallback for these cases. Signed-off-by: Jia Jie Ho <jiajie.ho@starfivetech.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2024-05-10crypto: starfive - Skip dma setup for zeroed messageJia Jie Ho
Skip dma setup and mapping for AES driver if plaintext is empty. Signed-off-by: Jia Jie Ho <jiajie.ho@starfivetech.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2024-04-02crypto: starfive - Use dma for aes requestsJia Jie Ho
Convert AES module to use dma for data transfers to reduce cpu load and compatible with future variants. Signed-off-by: Jia Jie Ho <jiajie.ho@starfivetech.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-12-08crypto: starfive - Remove cfb and ofbHerbert Xu
Remove the unused CFB/OFB implementation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-12-01crypto: starfive - Pad adata with zeroesJia Jie Ho
Aad requires padding with zeroes up to 15 bytes in some cases. This patch increases the allocated buffer size for aad and prevents the driver accessing uninitialized memory region. v1->v2: Specify reason for alloc size change in descriptions.

2023-08-18crypto: jh7110 - Use new crypto_engine_op interfaceHerbert Xu
Use the new crypto_engine_op interface where the callback is stored in the algorithm object. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-08-18crypto: jh1100 - Remove prepare/unprepare requestHerbert Xu
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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-08-11crypto: starfive - fix return value check in starfive_aes_prepare_req()Yang Yingliang
kzalloc() returns NULL pointer not PTR_ERR() when it fails, so replace the IS_ERR() check with NULL pointer check. Fixes: e22471c2331c ("crypto: starfive - Add AES skcipher and aead support") Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-07-28crypto: starfive - Add AES skcipher and aead supportJia Jie Ho
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.
