[PATCH v2 3/3] dt-bindings: interconnect: split SM8450 to own schema

From: Krzysztof Kozlowski
Date: Wed Jan 11 2023 - 04:30:26 EST


SM8450 comes with interconnects having and missing IO address space, and
variable number of clocks, so split it from common file for easier
maintenance and to fix warnings like:

sm8450-hdk.dtb: interconnect-0: 'reg' is a required property
