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

Both SDX55 and SDX66 SoCs are using the Qualcomm version of the SMMU-500
IP. But the binding lists them under the non-qcom implementation which is
not correct.
So fix the binding by moving these two SoCs under "qcom,smmu-500"
implementation.
