Subject: [PATCH v5 00/22] Enable Qualcomm Crypto Engine on sm8150 & sm8250
Date:   Wed, 10 Nov 2021 16:29:00 +0530
Message-Id: <20211110105922.217895-1-bhupesh.sharma@linaro.org>

Changes since v4:
=================
- v4 for sm8250 can be seen here: https://lore.kernel.org/linux-arm-msm/20211013105541.68045-1-bhupesh.sharma@linaro.org/
- v1 for sm8150 qce enablement can be seen here: https://lore.kernel.org/linux-arm-msm/20211013165823.88123-1-bhupesh.sharma@linaro.org/
- Merged the sm8150 and sm8250 enablement patches in the same patchset,
  as per suggestions from Bjorn.
- Dropped a couple of patches from v4, as these have been picked by
  Bjorn already via his tree.
- Addressed review comments from Vladimir, Thara and Rob.
- Collect Reviewed-by from Rob and Thara on some of the patches from the
  v4 patchset.

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 sm8150 and sm8250 SoCs.
The qce block 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 sm8150-mtp, sa8155p-adp, sm8250-mtp and RB5 boards (see [1]) and
also with crypto self-tests, including the fuzz tests
 (CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y).
