Changes since v3: ================= - v3 can be seen here: https://lore.kernel.org/linux-arm-msm/20210519143700.27392-1-bhupesh.sharma@linaro.org/ - Dropped a couple of patches from v3, on basis of the review comments: ~ [PATCH 13/17] crypto: qce: core: Make clocks optional ~ [PATCH 15/17] crypto: qce: Convert the device found dev_dbg() to dev_info() - Addressed review comments from Thara, Rob and Stephan Gerhold. - Collect Reviewed-by from Rob and Thara on some of the patches from the v3 patchset. Changes since v2: ================= - v2 can be seen here: https://lore.kernel.org/dmaengine/20210505213731.538612-1-bhupesh.sharma@linaro.org/ - Drop a couple of patches from v1, which tried to address the defered probing of qce driver in case bam dma driver is not yet probed. Replace it instead with a single (simpler) patch [PATCH 16/17]. - Convert bam dma and qce crypto dt-bindings to YAML. - Addressed review comments from Thara, Bjorn, Vinod and Rob. Changes since v1: ================= - v1 can be seen here: https://lore.kernel.org/linux-arm-msm/20210310052503.3618486-1-bhupesh.sharma@linaro.org/ - v1 did not work well as reported earlier by Dmitry, so v2 contains the following changes/fixes: ~ Enable the interconnect path b/w BAM DMA and main memory first before trying to access the BAM DMA registers. ~ Enable the interconnect path b/w qce crytpo and main memory first before trying to access the qce crypto registers. ~ Make sure to document the required and optional properties for both BAM DMA and qce crypto drivers. ~ Add a few debug related print messages in case the qce crypto driver passes or fails to probe. ~ Convert the qce crypto driver probe to a defered one in case the BAM DMA or the interconnect driver(s) (needed on specific Qualcomm parts) are not yet probed. Qualcomm crypto engine is also available on sm8250 SoC. It supports hardware accelerated algorithms for encryption and authentication. It also provides support for aes, des, 3des encryption algorithms and sha1, sha256, hmac(sha1), hmac(sha256) authentication algorithms. Tested the enabled crypto algorithms with cryptsetup test utilities on sm8250-mtp and RB5 board (see [1]) and also with crypto self-tests, including the fuzz tests (CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y). Note that this series is rebased on a SMMU related fix from Arnd applied on either linus's tip of linux-next's tip (see [2]), without which the sm8250 based boards fail to boot with the latest tip.
