Subject: [PATCH v10 1/3] dt-bindings: sram: describe the IPQ5424 IMEM as mmio-sram
Date: Wed, 13 May 2026 10:30:30 +0530	[thread overview]
Message-ID: <20260513-wdt_reset_reason-v10-1-cebda08ab1ef@oss.qualcomm.com> (raw)
In-Reply-To: <20260513-wdt_reset_reason-v10-0-cebda08ab1ef@oss.qualcomm.com>

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.
