Subject: [PATCH v2 3/5] dt-bindings: i2c: mt7621: Document an7581 compatible
Date: Mon, 21 Jul 2025 20:05:54 +0200 [thread overview]
Message-ID: <20250721180710.2116-4-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20250721180710.2116-1-ansuelsmth@gmail.com>
Airoha SoC implement the same Mediatek logic for I2C bus with the only
difference of not having a dedicated reset line to reset it.
Add a dedicated compatible for the Airoha AN7581 SoC and reject the
unsupported property.
