Set the qcom,adreno-smmu compatible string for the GPU SMMU to enable
split pagetables.

Add a special implementation for the SMMU attached to most Adreno GPU
target triggered from the qcom,adreno-gpu-smmu compatible string. When
selected the driver will attempt to enable split pagetables.

Construct the io-pgtable config before calling the implementation specific
init_context function and pass it so the implementation specific function
can get a chance to change it before the io-pgtable is created.

Every Qcom Adreno GPU has an embedded SMMU for its own use. These
devices depend on unique features such as split pagetables,
different stall/halt requirements and other settings. Identify them
with a compatible string so that they can be identified in the
arm-smmu implementation specific code.
Another iteration of the split-pagetable support for arm-smmu and the Adreno GPU
SMMU. After email discussions [1] we opted to make a arm-smmu implementation for
specifically for the Adreno GPU and use that to enable split pagetable support
and later other implementation specific bits that we
Use the aperture settings from the IOMMU domain to set up the virtual
address range for the GPU. This allows us to transparently deal with
IOMMU side features (like split pagetables).

Patch looks correct - but could you please explain why it is
"The PM core always increments the runtime usage counter
before calling the ->suspend() callback and decrements it
after calling the ->resume() callback"
DPU and DSI are managed as runtime devices. When
suspend is triggered, PM core adds a refcount on all the
devices and calls device suspend,

requested on the device.
