Shouldn't this be something like oneOf ? It is not a range, but one of
those two specific values ?
Yes, "qcom,dsb-element-size" should be an optional option required in TPDM
devicetree. Other properties like "qcom,cmb-element-size",
"qcom,tc-element-size"
and etc. will be added in a later patch series.
I will update this doc according to your advice in the next version of
the patch.
