[PATCH v9 0/2] dt-bindings: dma: Add support for SM6115 and QCM2290 SoCs

[Bhupesh Sharma]

Add support for SM6115 and QCM2290 SoCs in qcom,bam-dma bindings.
Also increase iommu maxItems for BAM DMA to 6 which is the number
required on sm8250 SoC.

This patchset is rebased on linux-next/master.

Changes since v8:
-----------------
- v8 can be viewed here: https://www.spinics.net/lists/linux-crypto/msg72349.html
- As rest of the patches from v8 have been applied to linux-next, dropped them from v9.
- Added dma list and maintainer in Cc again as the Cc list got messed up while
  sending out v8.

Changes since v7:
-----------------
- v7 can be viewed here: https://lore.kernel.org/linux-arm-msm/20230519214813.2593271-1-bhupesh.sharma@linaro.org/
- Addressed Stephan's comment about RPM clocks for sm6115 crypto block in dtsi.
- Also fixed the iommu context ids for sm6115 crypto block in dtsi.

- Collected Acks, R-Bs and Tested-by for various patches.
- Addressed Konrad's comment about iommu sids for sm8150 and sm8250
  crypto node entries.
- Addressed Konrad's and Stephan's comments about adding RPM clock for
  crypto blocks on qcm2290 and sm6115.

Changes since v5:

-----------------
- v4 can be viewed here: https://lore.kernel.org/linux-arm-msm/20230331164323.729093-1-bhupesh.sharma@linaro.org/
- Collected R-Bs from Konrad for a couple of patches sent in v4.
- Fixed incorrect email IDs for a couple of patches sent in v3, which I used for
  some patches created on a different work machine.
- No functional changes since v3.

Changes since v3:
-----------------
- v3 can be viewed here: https://lore.kernel.org/linux-arm-msm/20230328092815.292665-1-bhupesh.sharma@linaro.org/
- Collected Acks from Krzysztof for a couple of patches sent in v3.
- Fixed review comments from Krzysztof regarding DMA binding document
  and also added a couple of new patches which are required to fix the
  'dtbs_check' errors highlighted after this fix.

- No functional change since v2. As the sdm845 patch from v1 was accepted in linux-next,
  dropped it from this version.

Changes since v1:

[PATCH v9 1/2] dt-bindings: dma: Add support for SM6115 and QCM2290 SoCs

[Bhupesh Sharma]

Add new compatible for BAM DMA engine version v1.7.4 which is
found on Qualcomm SM6115 and QCM2290 SoCs. Since its very similar
to v1.7.0 used on SM8150 like SoCs, mark the comptible scheme
accordingly.

While at it, also update qcom,bam-dma bindings to add comments
which describe the BAM DMA versions used in SM8150 and SM8250 SoCs.
This provides an easy reference for identifying the actual BAM DMA
version available on Qualcomm SoCs.

[PATCH v9 2/2] dt-bindings: dma: Increase iommu maxItems for BAM DMA

[Bhupesh Sharma]

Since SM8250 BAM DMA engine supports six iommu entries,
increase the maxItems in the iommu property section, without
which 'dtbs_check' would throw errors.
