[PATCH 0/3] Fix SMMU on SDX55 and SDX65

Hi,

Both SDX55 and SDX65 SoCs are using the Qcom version of the ARM SMMU-500
IP. Even though the SoC specfic compatibles were being used in devicetree,
the compatibles were not added to the arm-smmu-qcom driver. So they end up
using the generic ARM SMMU-500 driver instead.

Spotting this discrepancy, the recent arm,smmu bindings change moved these
SoCs under the non-qcom implementation of the SMMU.

This series fixes the binding by moving the compatibles under qcom impl.
and also adding the "qcom,smmu-500" fallback compatible to the devicetree
so that the qcom implementation can be used without adding SoC specific
entries to the driver.

Thanks,
Mani
