This is a predecessor of the current supported EIP197. It doesn't require a firmware but instead it's embedded in the SoC. First patch extend guard for spinlock_bh. The other actually implement Documentation and Driver. The Driver pass all the normal selft test for the supported algo and also pass the EXTRA test with fuzz_iterations set to 10000. Changes v8: - Rework export and update to not sleep on exporting state (consume pending packet in update and return -EINPROGRESS) Changes v7: - Fix copypaste error in __eip93_hash_init - Rework import/export to actually export the partial hash (we actually unmap DMA on export) - Rename no_finalize variable to better partial_hash - Rename 3rd commit title and drop Mediatek from title. - Add Cover Letter - Add Reviewed-by to DT commit (cumulative changes from old series that had changelog in each patch) Changes v6: - Add SoC specific compatible - Add now supported entry for compatible with no user Changes v5: - Add Ack tag to guard patch - Comment out compatible with no current user - Fix smatch warning (reported by Dan Carpenter) Changes v4: - Out of RFC - Add missing bitfield.h - Drop useless header Changes v3: - Mute warning from Clang about C23 - Fix not inizialized err - Drop unused variable - Add SoC compatible with generic one Changes v2: - Rename all variables from mtk to eip93 - Move to inside-secure directory - Check DMA map errors - Use guard API for spinlock - Minor improvements to code - Add guard patch - Change to better compatible - Add description for EIP93 models Christian Marangi (3): spinlock: extend guard with spinlock_bh variants dt-bindings: crypto: Add Inside Secure SafeXcel EIP-93 crypto engine crypto: Add Inside Secure SafeXcel EIP-93 crypto engine support .../crypto/inside-secure,safexcel-eip93.yaml | 67 ++ MAINTAINERS | 7 + drivers/crypto/Kconfig | 1 + drivers/crypto/Makefile | 1 + drivers/crypto/inside-secure/eip93/Kconfig | 20 + drivers/crypto/inside-secure/eip93/Makefile | 5 + .../crypto/inside-secure/eip93/eip93-aead.c | 710 +++++++++++++ .../crypto/inside-secure/eip93/eip93-aead.h | 38 + .../crypto/inside-secure/eip93/eip93-aes.h | 16 + .../crypto/inside-secure/eip93/eip93-cipher.c | 413 ++++++++ .../crypto/inside-secure/eip93/eip93-cipher.h | 60 ++ .../crypto/inside-secure/eip93/eip93-common.c | 822 +++++++++++++++ .../crypto/inside-secure/eip93/eip93-common.h | 23 + .../crypto/inside-secure/eip93/eip93-des.h | 16 + .../crypto/inside-secure/eip93/eip93-hash.c | 987 ++++++++++++++++++ .../crypto/inside-secure/eip93/eip93-hash.h | 77 ++ .../crypto/inside-secure/eip93/eip93-main.c | 502 +++++++++ .../crypto/inside-secure/eip93/eip93-main.h | 152 +++ .../crypto/inside-secure/eip93/eip93-regs.h | 335 ++++++ include/linux/spinlock.h | 13 + 20 files changed, 4265 insertions(+) create mode 100644 Documentation/devicetree/bindings/crypto/inside-secure,safexcel-eip93.yaml create mode 100644 drivers/crypto/inside-secure/eip93/Kconfig create mode 100644 drivers/crypto/inside-secure/eip93/Makefile create mode 100644 drivers/crypto/inside-secure/eip93/eip93-aead.c create mode 100644 drivers/crypto/inside-secure/eip93/eip93-aead.h create mode 100644 drivers/crypto/inside-secure/eip93/eip93-aes.h create mode 100644 drivers/crypto/inside-secure/eip93/eip93-cipher.c create mode 100644 drivers/crypto/inside-secure/eip93/eip93-cipher.h create mode 100644 drivers/crypto/inside-secure/eip93/eip93-common.c create mode 100644 drivers/crypto/inside-secure/eip93/eip93-common.h create mode 100644 drivers/crypto/inside-secure/eip93/eip93-des.h create mode 100644 drivers/crypto/inside-secure/eip93/eip93-hash.c create mode 100644 drivers/crypto/inside-secure/eip93/eip93-hash.h create mode 100644 drivers/crypto/inside-secure/eip93/eip93-main.c create mode 100644 drivers/crypto/inside-secure/eip93/eip93-main.h create mode 100644 drivers/crypto/inside-secure/eip93/eip93-regs.h
