The series contains Qualcomm Crypto Engine DT bindings documentation and driver changes, which modify a set of accepted compatible property values, which is needed to provide a unified and fine-grained support of the driver on old and new platforms. In addition due to QCE IP changes on new Qualcomm platforms, it is reflected in updates to valid device tree properties, namely added iommu, interconnects and optional clocks. Qualcomm crypto engine (QCE) is available on several Snapdragon 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. Changes since v9: ================= - v9 can be found here: https://lore.kernel.org/linux-crypto/20230208183755.2907771-1-vladimir.zapolskiy@xxxxxxxxxx/ - Added a new generic 'qcom,qce' compatible name, since IP is runtime discoverable, however two new SoC name based compatibles are left due to necessity to differentiate various lists of required properties. - Updated documentation according to review comments by Krzysztof. - Removed platform specific changes in dtsi files, only one bisectable change in sm8550.dtsi is left in the series. - Added some commit tags, however a few given tags by Krzysztof are not added, since the previous tagged changes were noticeably reworked. Changes since v8: ================= - v8 can be found here: https://lore.kernel.org/all/20230202135036.2635376-1-vladimir.zapolskiy@xxxxxxxxxx/ - Rebased the series on top of linux-next, sm8550 qce support is already found in the tree. - Reduced the list of QCE IP compatibles in the driver, added one more compatible for backward DTB ABI compatibility. - Replaced a documentation change from Neil Armstrong by a more advanced version of it per review comments from Krzysztof Kozlowski about clock and clock-names properties. - Added changes to all relevant Qualcomm platform dtsi files according to the changes in the scheme file. - Added QCE support on SM8250 platform. Changes since v7: ================= - v7 can be found here: https://lore.kernel.org/linux-arm-msm/20220920114051.1116441-1-bhupesh.sharma@xxxxxxxxxx - Added a change by Neil Armstrong to document clocks and clock-names properties as optional, - At the moment do not add Bhupesh as a new QCE driver maintainer, - Minor updates to device tree binding documentation and qce driver, in particular added more compatibles and fixed lesser issues. Changes since v6: ================= - v6 can be seen here: https://lore.kernel.org/linux-arm-msm/30756e6f-952f-ccf2-b493-e515ba4f0a64@xxxxxxxxxx/ - As per Krzysztof's suggestion on v6, clubbed the crypto driver and dt-bindings changes together. Now the overall v5 patchset into 3 separate patchsets, one each for the following areas to allow easier review and handling from the maintainer: arm-msm, crypto and dma Changes since v5: ================= - v5 can be seen here: https://lore.kernel.org/lkml/20211110105922.217895-1-bhupesh.sharma@xxxxxxxxxx/ - As per Bjorn's suggestion on irc, broke down the patchset into 4 separate patchsets, one each for the following areas to allow easier review and handling from the maintainer: arm-msm, crypto, dma and devicetree - Addressed Rob's, Vladimir's and Bjorn's review comments received on v5. - Added Tested-by from Jordan received on the v5. Changes since v4: ================= - v4 for sm8250 can be seen here: https://lore.kernel.org/linux-arm-msm/20211013105541.68045-1-bhupesh.sharma@xxxxxxxxxx/ - v1 for sm8150 qce enablement can be seen here: https://lore.kernel.org/linux-arm-msm/20211013165823.88123-1-bhupesh.sharma@xxxxxxxxxx/ - 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@xxxxxxxxxx/ - 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@xxxxxxxxxx/ - 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@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.
