- Folded Neil's SM8450 dts patch in this series.
- Addressed review comments from Rob, Stephan and Konrad.
- Collected Konrad's R-B for [PATCH 5/9].

This patchset enables Crypto Engine support for Qualcomm SoCs like
SM6115, SM8150, SM8250, SM8350 and SM8450.

- SM8250 crypto engine patch utilizes the work already done by myself and
  Vladimir.
- SM8350 crypto engine patch utilizes the work already done by Robert.
- SM8450 crypto engine patch utilizes the work already done by Neil.

Also this patchset is rebased on linux-next/master.

[PATCH v8 01/11] 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.

Bjorn has applied the dts patches from this series to his tree.
As suggested by him, can you please pick patches [PATCH 1/11] and
[PATCH 2/11] from this series via the 'dmaengine' tree.

Seems some Cc fields got messed up while sending the patchset, so
Cc'ing the dmaengine list again.

Thanks,
Bhupesh

Sure, I have sent a v9, which can be seen here:

Please help review.

[PATCH v8 02/11] dt-bindings: dma: Increase iommu maxItems for BAM DMA

Since SM8450 BAM DMA engine supports five iommu entries,
increase the maxItems in the iommu property section, without
which 'dtbs_check' reports the following error:

This needs at least 6 (sm8250).

Also, please drop error message, because it is not true. The files do
not have such device node, so you cannot have such warning.

Please rewrite the commit msg to explain that certain devices, e.g.
sm8250, use more iommus.

Best regards,
Krzysztof

I have sent a v9 (which can be seen here: 
<https://lore.kernel.org/linux-arm-msm/20230630082230.2264698-1-bhupesh.sharma@linaro.org/>), 
which addresses your review comments shared on v8.

Please help review.

[PATCH v8 05/11] dt-bindings: qcom-qce: Fix compatible combinations for SM8150 and IPQ4019 SoCs

[Bhupesh Sharma]

Currently the compatible list available in 'qce' dt-bindings does not
support SM8150 and IPQ4019 SoCs directly which may lead to potential
'dtbs_check' error(s).

Fix the same.

Bjorn has applied the dts patches from this series to his tree.
As suggested by him, can you please pick patches [PATCH 5/11] and
[PATCH 6/11] from this series via the 'crypto' tree.

Seems some Cc fields got messed up while sending the patchset, so
Cc'ing the list(s) again.

Thanks,
Bhupesh

The core clock for the Crypto Engine block on Qualcomm SoCs SM6115 and
QCM2290 are provided via the RPM block.

So mark the compatibles for these SoCs to indicate that only 'core'
clock is required for such SoCs.

#regzbot title: HDK8350 silently crashes early on boot

Hi, this landed in the next but unfortunately it causes silent crash
(and reboot) of HDK8350. Reverting this commit helps.

Can it be that some dependency is missing in linux-next or Bjorn's tree?
Shall we revert it?

Downstream also references the following SIDs:

iommus = <&apps_smmu 0x592 0>,
	 <&apps_smmu 0x598 0>,
	 <&apps_smmu 0x599 0>,
	 <&apps_smmu 0x59F 0>;

that might be the culprit

I already tried iommus from downstream from:
1. qcrypto node (0x584, 0x594)
2. qcedev (0x586, 0x596)
3. qcom_cedev_ns_cb (0x592, 0x598, 0x599, 0x59F), although with 0x0011
last argument.

Same results, but indeed iommu would be nice reason here.

I also double checked the version of block (BAM DMA is v1.7.4) and other
properties. When I disabled crypto but left BAM DMA, the result was the
same, thus it is maybe the BAM who causes abort.


Best regards,
Krzysztof

I remember testing it on the sm8350-mtp and found no issues. Infact
Robert (the original author of the patch) had also done some testing
in the past.

I am sure - mtp v/s hdk board variation would not cause this, so let
me have a stab at it tomorrow.
