2018-03-30crypto: brcm - explicitly cast cipher to hash typeStefan Agner1-2/+2
In the AES cases enum spu_cipher_type and enum hash_type have the same values, so the assignment is fine. Explicitly cast the enum type conversion. This fixes two warnings when building with clang: drivers/crypto/bcm/cipher.c:821:34: warning: implicit conversion from enumeration type 'enum spu_cipher_type' to different enumeration type 'enum hash_type' [-Wenum-conversion] hash_parms.type = cipher_parms.type; ~ ~~~~~~~~~~~~~^~~~ drivers/crypto/bcm/cipher.c:1412:26: warning: implicit conversion from enumeration type 'enum spu_cipher_type' to different enumeration type 'enum hash_type' [-Wenum-conversion] hash_parms.type = ctx->cipher_type; ~ ~~~~~^~~~~~~~~~~ Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

The usage of of_device_get_match_data reduce the code size a bit. Furthermore, it prevents an improbable dereference when of_match_device() return NULL. Signed-off-by: Corentin Labbe <clabbe.montjoie@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2017-09-22crypto: brcm - Explicity ACK mailbox messageraveendra padasalagi1-55/+46
Add support to explicity ACK mailbox message because after sending message we can know the send status via error attribute of brcm_message. This is needed to support "txdone_ack" supported in mailbox controller driver.
