ac1207f516 dt-bindings: arm-smmu: Remove sdm845-cheza specific entry 
The firmware on SDM845-based Cheza boards did not provide the same
level of feature support for SMMUs (particularly around the Adreno
GPU integration).

Now that Cheza is being removed from the kernel (almost none exist at
this point in time), retire the entry as well.

Most notably, it's not being marked as deprecated instead, as there is
no indication that any more of those ~7 year old devboards will be
built.

sm8150 has an smmu-500 specifically for Adreno, where the GPU is allowed
to switch pagetables.  Document the allowed 3-compatibles for this,
similar to sc7280 and sm8250.

6c84bbd103 dt-bindings: arm-smmu: Add generic qcom,smmu-500 bindings 
Add generic bindings for the Qualcomm variant of the ARM MMU-500. It is
expected that all future platforms will use the generic qcom,smmu-500
compat string in addition to SoC-specific and the generic arm,mmu-500
ones. Older bindings are now described as deprecated.

Note: I have split the sdx55 and sdx65 from the legacy bindings. They
are not supported by the qcom SMMU implementation. I can suppose that
they are using the generic implementation rather than the
Qualcomm-speicific one.

3a12e8c065 dt-bindings: arm-smmu: add special case for Google Cheza platform 
Cheza fw does not properly program the GPU aperture to allow the
GPU to update the SMMU pagetables for context switches. The board file
works around this by dropping the "qcom,adreno-smmu" compat string.
Add this usecase to arm,smmu.yaml schema.

c02bda09f9 dt-bindings: arm-smmu: Document nvidia,memory-controller property 
On NVIDIA SoC's the ARM SMMU needs to interact with the memory
controller in order to map memory clients to the corresponding stream
IDs. Document how the nvidia,memory-controller property can be used to
achieve this.

Note that this is a backwards-incompatible change that is, however,
necessary to ensure correctness. Without the new property, most of the
devices would still work but it is not guaranteed that all will.
