This driver adds support for such hardware thus enabling hardware-accelerated hashing on the Keem Bay SoC for the following algorithms: - sha224 and hmac(sha224) - sha256 and hmac(sha256) - sha384 and hmac(sha384) - sha512 and hmac(sha512) - sm3 and hmac(sm3) The driver is passing crypto manager self-tests, including the extra tests (CRYPTO_MANAGER_EXTRA_TESTS=y). v1 -> v2: - Fixed issues with dt-bindings Daniele Alessandrelli (1): MAINTAINERS: Add maintainers for Keem Bay OCS HCU driver Declan Murphy (2): dt-bindings: crypto: Add Keem Bay OCS HCU bindings crypto: keembay: Add Keem Bay OCS HCU driver .../crypto/intel,keembay-ocs-hcu.yaml | 51 + MAINTAINERS | 11 + drivers/crypto/Kconfig | 2 + drivers/crypto/Makefile | 1 + drivers/crypto/keembay/Kconfig | 20 + drivers/crypto/keembay/Makefile | 5 + drivers/crypto/keembay/keembay-ocs-hcu-core.c | 1484 +++++++++++++++++ drivers/crypto/keembay/ocs-hcu.c | 593 +++++++ drivers/crypto/keembay/ocs-hcu.h | 115 ++ 9 files changed, 2282 insertions(+) create mode 100644 Documentation/devicetree/bindings/crypto/intel,keembay-ocs-hcu.yaml create mode 100644 drivers/crypto/keembay/Kconfig create mode 100644 drivers/crypto/keembay/Makefile create mode 100644 drivers/crypto/keembay/keembay-ocs-hcu-core.c create mode 100644 drivers/crypto/keembay/ocs-hcu.c create mode 100644 drivers/crypto/keembay/ocs-hcu.h base-commit: c3a98c3ad5c0dc60a1ac66bf91147a3f39cac96b
