[PATCH v2 0/7] Grab IPA IMEM slice through DT, part 2

From: Konrad Dybcio

Date: Thu Mar 05 2026 - 05:56:23 EST


The IPA IMEM slice addresses/sizes are hardcoded in the driver. That's
mucho no bueno, especially since the same versions of IPA are used
across a number of vastly different platforms, which invalidates that
approach completely.

This series wires up the IMEM slices in DT on almost all platforms
(need some more time for SDX55/65) and fills in the necessary bindings
holes.

Tested on SC7280 only, FWIW.

Patches 1-3 are good to go instantly, the rest must wait for the
bindings changes that were submitted in the series marked as a
dependency.
