However I don't think this is the only dependency. You add here several compatibles which are not supported. Best regards, Krzysztof

Please go through the cover letter where I mentioned that: '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 respective maintainer(s): 'arm-msm', 'crypto', 'dma' and 'devicetree' This patchset is directed for the 'devicetree' tree / area.' Basically now the patchset which had around 23 patches in v5 will send out as 4 separate patchsets one each for 'arm-msm', 'crypto', 'dma' and 'devicetree' trees. So when all the respective subsets are picked up, all the compatibles are in place. Thanks, Bhupesh

Keeping bindings separate from everything is not good approach. Either they should be with DTS or with driver changes. Otherwise how can we even look that they are matching DTS? Keeping them separate even makes impression there are no ABI breaks and bisectability issues... Best regards, Krzysztof

I see your point, but as I mentioned this was as per suggestions from other maintainers only :) Perhaps a good topic for the next LPC maintainers meetup - i.e. would maintainers be more happy with subpatches for their specific area v/s being cc'ed on a single patchset which touches other areas as well (but are required for enabling a feature in its entirety). Thanks, Bhupesh
Changes since v5: ================= - v5 can be seen here: https://lore.kernel.org/lkml/20211110105922.217895-1-bhupesh.sharma@linaro.org/ - 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 respective maintainer(s): 'arm-msm', 'crypto', 'dma' and 'devicetree' This patchset is directed for the 'arm-msm' tree / area. - Addressed Rob's, Vladimir's and Bjorn's review comments on v5. - Added Tested-by from Jordan received on the v5. - Also added a 'defconfig' change where I enabled the QCE block as a module. 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 (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. Note that this patchset is dependent on the dt-bindings patchset (see [1]) sent to devicetree list.
