Re: [PATCH v2 01/10] interconnect: qcom: osm-l3: Use platform-independent node ids

Hey Bjorn
Thanks for the patch.

On 11/11/22 08:55, Bjorn Andersson wrote:
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.

With the change in implementation, you can remove now remove the per soc
node id headers included in the driver. With ^^ done.
