Subject: [PATCH v1] dt-bindings: mmc: dwcmshc-sdhci: Fix resets array validation
Date: Wed, 11 Feb 2026 17:47:36 +0800 [thread overview]
Message-ID: <20260211094736.88-1-hehuan1@eswincomputing.com> (raw)
From: Huan He <hehuan1@eswincomputing.com>
The binding defines tuple-style reset-names items for some
compatibles, which implicitly enforces a fixed array length
via JSON Schema.
Defining global maxItems for resets and reset-names causes these
constraints to be intersected via allOf, resulting in an effective
minItems equal to the global maxItems. This leads to dtbs_check
failures reporting reset arrays as too short, even when the DTS
provides the correct number of entries.
Remove the global maxItems constraints and let the per-compatible
schema branches define the required reset array sizes explicitly.
Fixes: 30009a21f257 ("dt-bindings: mmc: sdhci-of-dwcmshc: Add Eswin EIC7700")
