[PATCH v3 0/7] arm64: dts: qcom: sa8775p: add more IOMMUs

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Add the GPU and PCIe IOMMUs for sa8775p platforms as well as the required
GPU clock controller driver.

NOTE: I didn't pick up Krzysztof's tag for patch 4/7 as the patch changed
significantly.

v2 -> v3:
- select QCOM_GDSC in Kconfig for the GPUCC module
- the GPU SMMU is actually an adreno SMMU so describe it as such and
  fix the DT
- fix the mapped memory size for the PCIe SMMU

v1 -> v2:
- remove unused include in the GPUCC driver
- remove unused clock from the GPUCC driver and make it compatible
  with the generic QCom GPUCC bindings
- put the new defconfig option in the right place (as per savedefconfig)
  and make the GPUCC driver a module rather than built-in
- describe the smmu clocks for sa8775p in dt-bindings

  arm64: defconfig: enable the SA8775P GPUCC driver
  arm64: dts: qcom: sa8775p: add the pcie smmu node
  arm64: dts: qcom: sa8775p: add the GPU clock controller node
  dt-bindings: iommu: arm,smmu: enable clocks for sa8775p Adreno SMMU
  arm64: dts: qcom: sa8775p: add the GPU IOMMU node

[PATCH v3 1/7] dt-bindings: clock: qcom: describe the GPUCC clock for SA8775P

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Add the compatible for the Qualcomm Graphics Clock control module present
on sa8775p platforms. It matches the generic QCom GPUCC description. Add
device-specific DT bindings defines as well.

[PATCH v3 6/7] dt-bindings: iommu: arm,smmu: enable clocks for sa8775p Adreno SMMU

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

The GPU SMMU will require the clocks property to be set so put the
relevant compatible into the adreno if-then block.

Err.. does it even boot like this? You dropped the qcom,smmu-500 compatible
which means it's getting bound to the generic SMMU driver (without
QC quirks). If that was a mistake, you should have had all 4

"qcom,sa8775p-smmu-500", qcom,adreno-smmu, "qcom,smmu-500", "arm,mmu-500"

Without falling into the qc-specific codepaths, the Adreno compat does
nothing.

I did that initially, then noticed dtbs_check fails because the
existing adreno GPUs implementing "arm,smmu-500" expect three
compatibles like in this commit. I did that and the driver still
probed the same so I assumed all's good. You're right of course, the
adreno impl is not being assigned without "qcom,smmu-500". Are the
bindings wrong in this case and should it be something like the
following?

This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions. However, there's no need to repost patches *only* to add the
tags. The upstream maintainer will do that for acks received on the
version they apply.

https://elixir.bootlin.com/linux/v5.17/source/Documentation/process/submitting-patches.rst#L540

If a tag was not added on purpose, please state why and what changed.


Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

Best regards,
Krzysztof
