[net-next PATCH v5 0/3] Grab IPA IMEM slice through DT

From: Konrad Dybcio <konradybcio@kernel.org>
Date: 2026-02-24 11:35:18
Also in: linux-arm-msm, linux-devicetree, lkml

This adds the necessary driver change to migrate over from
hardcoded-per-IPA-version-but-varying-per-implementation numbers, while
unfortunately keeping them in there for backwards compatibility.

The DT changes will be submitted in a separate series, this one is OK
to merge independently.
