This patch series adds kernel driver support for StarFive JH7110 crypto engine. The first patch adds Documentations for the device and Patch 2 adds device probe and DMA init for the module. Patch 3 adds crypto and DMA dts node for VisionFive 2 board. Patch 4 adds hash/hmac support to the module. Patch 3 needs to be applied on top of: https://lore.kernel.org/lkml/20230424135409.6648-3-xingyu.wu@xxxxxxxxxxxxxxxx/ Patch 4 needs to be applied on top of: https://lore.kernel.org/linux-crypto/ZEEOXIHwqKblKfBJ@xxxxxxxxxxxxxxxxxxx/T/#u Changes v6->v7 - Remove NULL assignment as struct is kzalloc()-ed (Christophe) - Do clk_disable_unprepare and assert reset if probe failed (Christophe) - Remove unnecessary null pointer check (Christophe) - Update module name in Kconfig description (Christophe) Changes v5->v6 - Remove set_crypt in export as request will have been created by init/updated calls (Herbert) - Use new helper to set statesize of crypto_ahash (Herbert) - Use crypto_ahash_blocksize instead of crypto_ahash_tfm (Herbert) - Switch to init_tfm/exit_tfm instead of cra_init/cra_exit (Herbert) Changes v4->v5 - Schedule tasklet from IRQ handler instead of using completion to sync events (Herbert) Changes v3->v4: - Use fallback for non-aligned cases as hardware doesn't support hashing piece-meal (Herbert) - Use ahash_request_set_* helpers to update members of ahash_request (Herbert) - Set callbacks for async fallback (Herbert) - Remove completion variable and use dma_callback to do the rest of processing instead. (Herbert) Changes v2->v3: - Only implement digest and use fallback for other ops (Herbert) - Use interrupt instead of polling for hash complete (Herbert) - Remove manual data copy from out-of-bound memory location as it will be handled by DMA API. (Christoph & Herbert) Changes v1->v2: - Fixed yaml filename and format (Krzysztof) - Removed unnecessary property names in yaml (Krzysztof) - Moved of_device_id table close to usage (Krzysztof) - Use dev_err_probe for error returns (Krzysztof) - Dropped redundant readl and writel wrappers (Krzysztof) - Updated commit signed offs (Conor) - Dropped redundant node in dts, module set to on in dtsi (Conor) Jia Jie Ho (4): dt-bindings: crypto: Add StarFive crypto module crypto: starfive - Add crypto engine support riscv: dts: starfive: Add crypto and DMA node for VisionFive 2 crypto: starfive - Add hash and HMAC support .../crypto/starfive,jh7110-crypto.yaml | 70 ++ MAINTAINERS | 7 + arch/riscv/boot/dts/starfive/jh7110.dtsi | 28 + drivers/crypto/Kconfig | 1 + drivers/crypto/Makefile | 1 + drivers/crypto/starfive/Kconfig | 21 + drivers/crypto/starfive/Makefile | 4 + drivers/crypto/starfive/jh7110-cryp.c | 240 +++++ drivers/crypto/starfive/jh7110-cryp.h | 127 +++ drivers/crypto/starfive/jh7110-hash.c | 892 ++++++++++++++++++ 10 files changed, 1391 insertions(+) create mode 100644 Documentation/devicetree/bindings/crypto/starfive,jh7110-crypto.yaml create mode 100644 drivers/crypto/starfive/Kconfig create mode 100644 drivers/crypto/starfive/Makefile create mode 100644 drivers/crypto/starfive/jh7110-cryp.c create mode 100644 drivers/crypto/starfive/jh7110-cryp.h create mode 100644 drivers/crypto/starfive/jh7110-hash.c -- 2.25.1
