Subject: [PATCH v8 1/5] dt-bindings: sram: describe the IPQ5424 IMEM as mmio-sram
Date: Thu, 26 Feb 2026 22:29:36 +0530	[thread overview]
Message-ID: <20260226-wdt_reset_reason-v8-1-011c3a8cb6ff@oss.qualcomm.com> (raw)
In-Reply-To: <20260226-wdt_reset_reason-v8-0-011c3a8cb6ff@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.
