dt-bindings: arm-smmu: qcom: Add Hawi compatible for Application processor

[PATCH v2] dt-bindings: arm-smmu: qcom: Add Hawi compatible for Application processor

Posted by Mukesh Ojha 1 month, 2 weeks ago

Commit 5e8323c3d528 ("dt-bindings: arm-smmu: qcom: Add compatible for
Hawi SoC") was intended for the APSS SMMU but was mistakenly placed
under the Adreno GPU SMMU section. Since that compatible is also valid
for the Hawi GPU SMMU, keep that commit as-is and add proper
documentation for the Hawi APSS SMMU here.

 - Not a fix commit after discussion.
 - Not removing the earlier commit change instead add one for APSS
   SMMU.

Would be nice to see explanation what is APSS. We do ask for that every
couple of months.
