Hi, This patch series adds the Intel Keem Bay OCS ECC crypto driver, which enables hardware-accelerated 'ecdh-nist-p256' and 'ecdh-nist-p384' on the Intel Keem Bay SoC. The following changes to core crypto code are also done: - KPP support is added to the crypto engine (so that the new driver can use it). - 'crypto/ecc.h' is moved to 'include/crypto/internal' (so that this and other drivers can use the symbols exported by 'crypto/ecc.c'). - A few additional functions from 'crypto/ecc.c' are exported (so that this and other drivers can use them and avoid code duplication). The driver passes crypto manager self-tests. A previous version of this patch series was submitted as an RFC: https://lore.kernel.org/linux-crypto/20201217172101.381772-1-daniele.alessandrelli@xxxxxxxxxxxxxxx/ Changes from previous RFC submission (RFC-v1): - Switched to the new 'ecdh-nist-p256' and 'ecdh-nist-p384' algorithm names - Dropped the CONFIG_CRYPTO_DEV_KEEMBAY_OCS_ECDH_GEN_PRIV_KEY_SUPPORT Kconfig option Daniele Alessandrelli (2): crypto: ecc - Move ecc.h to include/crypto/internal crypto: ecc - Export additional helper functions Prabhjot Khurana (3): crypto: engine - Add KPP Support to Crypto Engine dt-bindings: crypto: Add Keem Bay ECC bindings crypto: keembay-ocs-ecc - Add Keem Bay OCS ECC Driver Documentation/crypto/crypto_engine.rst | 4 + .../crypto/intel,keembay-ocs-ecc.yaml | 47 + MAINTAINERS | 11 + crypto/crypto_engine.c | 26 + crypto/ecc.c | 14 +- crypto/ecdh.c | 2 +- crypto/ecdsa.c | 2 +- crypto/ecrdsa.c | 2 +- crypto/ecrdsa_defs.h | 2 +- drivers/crypto/keembay/Kconfig | 19 + drivers/crypto/keembay/Makefile | 2 + drivers/crypto/keembay/keembay-ocs-ecc.c | 1017 +++++++++++++++++ include/crypto/engine.h | 5 + {crypto => include/crypto/internal}/ecc.h | 36 + 14 files changed, 1180 insertions(+), 9 deletions(-) create mode 100644 Documentation/devicetree/bindings/crypto/intel,keembay-ocs-ecc.yaml create mode 100644 drivers/crypto/keembay/keembay-ocs-ecc.c rename {crypto => include/crypto/internal}/ecc.h (90%) base-commit: 06f6e365e2ecf799c249bb464aa9d5f055e88b56 -- 2.31.1
