[PATCH v8 1/5] dt-bindings: sram: describe the IPQ5424 IMEM as mmio-sram

From: Kathiravan Thirumoorthy

Date: Thu Feb 26 2026 - 13:18:09 EST


IMEM shouldn’t be treated as a syscon or simple-mfd because it’s really
just on‑chip SRAM, not a block of control registers or a device with
multiple hardware functions.

Describing it as generic mmio‑sram keeps the model simple and closer to
what the hardware actually is.
