Merge tag 'v6.2-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "API: - Optimise away self-test overhead when they are disabled - Support symmetric encryption via keyring keys in af_alg - Flip hwrng default_quality, the default is now maximum entropy Algorithms: - Add library version of aesgcm - CFI fixes for assembly code - Add arm/arm64 accelerated versions of sm3/sm4 Drivers: - Remove assumption on arm64 that kmalloc is DMA-aligned - Fix selftest failures in rockchip - Add support for RK3328/RK3399 in rockchip - Add deflate support in qat - Merge ux500 into stm32 - Add support for TEE for PCI ID 0x14CA in ccp - Add mt7986 support in mtk - Add MaxLinear platform support in inside-secure - Add NPCM8XX support in npcm" * tag 'v6.2-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (184 commits) crypto: ux500/cryp - delete driver crypto: stm32/cryp - enable for use with Ux500 crypto: stm32 - enable drivers to be used on Ux500 dt-bindings: crypto: Let STM32 define Ux500 CRYP hwrng: geode - Fix PCI device refcount leak hwrng: amd - Fix PCI device refcount leak crypto: qce - Set DMA alignment explicitly crypto: octeontx2 - Set DMA alignment explicitly crypto: octeontx - Set DMA alignment explicitly crypto: keembay - Set DMA alignment explicitly crypto: safexcel - Set DMA alignment explicitly crypto: hisilicon/hpre - Set DMA alignment explicitly crypto: chelsio - Set DMA alignment explicitly crypto: ccree - Set DMA alignment explicitly crypto: ccp - Set DMA alignment explicitly crypto: cavium - Set DMA alignment explicitly crypto: img-hash - Fix variable dereferenced before check 'hdev->req' crypto: arm64/ghash-ce - use frame_push/pop macros consistently crypto: arm64/crct10dif - use frame_push/pop macros consistently crypto: arm64/aes-modes - use frame_push/pop macros consistently ...
