[PATCH v4 0/5] crypto: Add Keem Bay OCS HCU driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Intel Keem Bay SoC has an Offload Crypto Subsystem (OCS) featuring a
Hashing Control Unit (HCU) for accelerating hashing operations.

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).

v3 -> v4:
- Addressed comments from Mark Gross.
- Added Reviewed-by-tag from Rob Herring to DT binding patch.
- Driver reworked to better separate the code interacting with the hardware
  from the code implementing the crypto ahash API.
- Main patch split into 3 different patches to simplify review (patch series is
  now composed of 5 patches)

v2 -> v3:
- Fixed more issues with dt-bindings (removed useless descriptions for reg,
  interrupts, and clocks)

v1 -> v2:
- Fixed issues with dt-bindings
