Changes since v1: ================= - v1 can be seen here: https://lore.kernel.org/linux-arm-msm/20210310052503.3618486-1-bhupesh.sharma@xxxxxxxxxx/ - 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]). While at it, also make a minor fix in 'sdm845.dtsi', to make sure it confirms with the other .dtsi files which expose crypto nodes on qcom SoCs.
