[ Upstream commit 42314738906380cbd3b6e9caf3ad34e1b2d66035 ] Add the compatible for the separate IOMMU on SDM670 for the Adreno GPU. This IOMMU has the compatible strings: "qcom,sdm670-smmu-v2", "qcom,adreno-smmu", "qcom,smmu-v2" While the SMMU 500 doesn't need an entry for this specific SoC, the SMMU v2 compatible should have its own entry, as the fallback entry in arm-smmu.c handles "qcom,smmu-v2" without per-process page table support unless there is an entry here. This entry can't be the "qcom,adreno-smmu" compatible because dedicated GPU IOMMUs can also be SMMU 500 with different handling.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
