[net-next PATCH v3 0/3] Grab IPA IMEM slice through DT

From: Konrad Dybcio <konradybcio@kernel.org>
Date: 2026-02-17 13:30:41
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.

Changes in v3:
- Pick up tags, rebase (effectively a NOP)
- Add actual binding constraints for modem-tables, drop Alex's r-b
- Better describe the purpose of this region, as much as I can anyway
- Link to v2: https://lore.kernel.org/r/20250527-topic-ipa_imem-v2-0-6d1aad91b841@oss.qualcomm.com (local)

Changes in v2:
- Actually pass the retrieved data to the target function
- Re-wrap comments to match net/ style

- Pick up tags
- Link to v1: https://lore.kernel.org/r/20250523-topic-ipa_imem-v1-0-b5d536291c7f@oss.qualcomm.com (local)
