Various dt-bindings fixes

[PATCH 01/11] dt-bindings: iommu: qcom,iommu: Add optional TBU clock

Posted by Konrad Dybcio 11 months, 1 week ago

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

Some MMU instances feature a Translation Buffer Unit (TBU), which comes
with its own clock. Allow describing it.
