Merge tag 'v6.10-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "API: - Remove crypto stats interface Algorithms: - Add faster AES-XTS on modern x86_64 CPUs - Forbid curves with order less than 224 bits in ecc (FIPS 186-5) - Add ECDSA NIST P521 Drivers: - Expose otp zone in atmel - Add dh fallback for primes > 4K in qat - Add interface for live migration in qat - Use dma for aes requests in starfive - Add full DMA support for stm32mpx in stm32 - Add Tegra Security Engine driver Others: - Introduce scope-based x509_certificate allocation" * tag 'v6.10-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (123 commits) crypto: atmel-sha204a - provide the otp content crypto: atmel-sha204a - add reading from otp zone crypto: atmel-i2c - rename read function crypto: atmel-i2c - add missing arg description crypto: iaa - Use kmemdup() instead of kzalloc() and memcpy() crypto: sahara - use 'time_left' variable with wait_for_completion_timeout() crypto: api - use 'time_left' variable with wait_for_completion_killable_timeout() crypto: caam - i.MX8ULP donot have CAAM page0 access crypto: caam - init-clk based on caam-page0-access crypto: starfive - Use fallback for unaligned dma access crypto: starfive - Do not free stack buffer crypto: starfive - Skip unneeded fallback allocation crypto: starfive - Skip dma setup for zeroed message crypto: hisilicon/sec2 - fix for register offset crypto: hisilicon/debugfs - mask the unnecessary info from the dump crypto: qat - specify firmware files for 402xx crypto: x86/aes-gcm - simplify GCM hash subkey derivation crypto: x86/aes-gcm - delete unused GCM assembly code crypto: x86/aes-xts - simplify loop in xts_crypt_slowpath() hwrng: stm32 - repair clock handling ...
