Subject: [PATCH 0/2] SM6375 GPU SMMU

This series hooks up the GPU SMMU, as well as GPUCC as its direct
dependency.

The thing sadly can't seem to be able to do PPPT, not even on downstream..

Subject: [PATCH 1/2] dt-bindings: arm-smmu: Add SM6375 GPU SMMU

SM6375 has a "Qualcomm SMMU V2" implementation for its GPU SMMU. It
does not however qualify for the qcom,adreno-smmu compatible, as it can
not do split pagetables. It consumes a single clock and a single genpd.
