Subject: [PATCH 01/10] interconnect: qcom: osm-l3: Use platform-independent node ids
The identifiers used for nodes needs to be unique in the running system,
but defining them per platform results in a lot of duplicated
definitions and prevents us from using generic compatibles.
As these identifiers are not exposed outside the kernel, change to use
driver-local numbers, picked completely at random.
