Yes, and the $ref defines it as [1, 2], so initially I thought this should be narrowed. However it seems 1 or 2 are still valid for all of Qcom interconnects, so your "true" is correct.

Add bindings for Qualcomm SM6350 Network-On-Chip interconnect devices. As SM6350 has two pairs of NoCs sharing the same reg, allow this in the binding documentation, as was done for qcm2290. Because the main qcom,rpmh.yaml file is getting too complicated for our use cases, create a new qcom,rpmh-common.yaml and a separate qcom,sm6350-rpmh.yaml that defines our new bindings.
