Hi, This patch set adds the CAAM crypto engine driver for DPAA2 (Data Path Acceleration Architecture v2) found on ARMv8-based SoCs like LS1088A, LS2088A, LX2160A. Previously sent RFC can be found here: https://www.mail-archive.com/linux-crypto@xxxxxxxxxxxxxxx/msg27290.html Driver consists of: -DPSECI (Data Path SEC Interface) backend - low-level API that allows to manage DPSECI devices (DPAA2 objects) that sit on the Management Complex (MC) fsl-mc bus -algorithms frontend - AEAD, skcipher and ahash algorithms implementation Patches 1-4 are fsl-mc bus and DPIO dependencies. Stuart, Laurentiu, Leo, Roy, please review the patches and let me know if you have anything against going with them through the cryptodev tree. Patches 5-10 are the core of the patch set, adding the driver. For symmetric encryption the new skcipher interface is used. Patch 11 enables driver on arm64. It will be built only if dependency on DPIO (CONFIG_FSL_MC_DPIO) is satisfied. Note: multiple modprobe/rmmod won't work without the following patches [5/7,v7] bus/fsl-mc: support dma configure for devices on fsl-mc bus https://patchwork.kernel.org/patch/10594179 [7/7,v7] arm64: dts: ls208xa: comply with the iommu map binding for fsl_mc https://patchwork.kernel.org/patch/10594171 (for LS1088A a similar DT update is needed) Thanks, Horia Horia Geantă (11): bus: fsl-mc: add support for dpseci device type Revert "staging: fsl-mc/dpio: remove couple of unused functions" soc: fsl: dpio: add frame list format support soc: fsl: dpio: add congestion notification support crypto: caam - add DPAA2-CAAM (DPSECI) backend API crypto: caam - add Queue Interface v2 error codes crypto: caam/qi2 - add DPAA2-CAAM driver crypto: caam/qi2 - add skcipher algorithms crypto: caam - export ahash shared descriptor generation crypto: caam/qi2 - add support for ahash algorithms arm64: defconfig: enable CAAM crypto engine on QorIQ DPAA2 SoCs arch/arm64/configs/defconfig | 1 + drivers/bus/fsl-mc/fsl-mc-bus.c | 5 + drivers/crypto/Makefile | 2 +- drivers/crypto/caam/Kconfig | 55 +- drivers/crypto/caam/Makefile | 10 +- drivers/crypto/caam/caamalg_qi2.c | 5165 +++++++++++++++++++++++++++++++++++ drivers/crypto/caam/caamalg_qi2.h | 223 ++ drivers/crypto/caam/caamhash.c | 79 +- drivers/crypto/caam/caamhash_desc.c | 80 + drivers/crypto/caam/caamhash_desc.h | 21 + drivers/crypto/caam/compat.h | 1 + drivers/crypto/caam/dpseci.c | 426 +++ drivers/crypto/caam/dpseci.h | 333 +++ drivers/crypto/caam/dpseci_cmd.h | 149 + drivers/crypto/caam/error.c | 79 +- drivers/crypto/caam/error.h | 6 +- drivers/crypto/caam/regs.h | 2 + drivers/soc/fsl/dpio/dpio-service.c | 58 + include/linux/fsl/mc.h | 6 + include/soc/fsl/dpaa2-fd.h | 242 ++ include/soc/fsl/dpaa2-global.h | 15 + include/soc/fsl/dpaa2-io.h | 4 + 22 files changed, 6871 insertions(+), 91 deletions(-) create mode 100644 drivers/crypto/caam/caamalg_qi2.c create mode 100644 drivers/crypto/caam/caamalg_qi2.h create mode 100644 drivers/crypto/caam/caamhash_desc.c create mode 100644 drivers/crypto/caam/caamhash_desc.h create mode 100644 drivers/crypto/caam/dpseci.c create mode 100644 drivers/crypto/caam/dpseci.h create mode 100644 drivers/crypto/caam/dpseci_cmd.h -- 2.16.2
