Subject: [PATCH v9 07/21] dt-bindings: media: i2c: max96712: add support for I2C ATR
Date: Wed, 11 Mar 2026 09:17:19 +0200 [thread overview]
Message-ID: <20260311-gmsl2-3_serdes-v9-7-41499f09004f@analog.com> (raw)
In-Reply-To: <20260311-gmsl2-3_serdes-v9-0-41499f09004f@analog.com>
From: Cosmin Tanislav <demonsingur@gmail.com>
MAX96712 and MAX96724 have more than one GMSL2 link, and each link is
capable of connecting to a separate serializer. If these serializers
have the same CFG pins configuration, they will also have the same I2C
address, causing conflicts unless the deserializer changes the address
of the connected serializers.
The MAX96712 and MAX96724 support changing the I2C address of the
connected serializers.
Document this capability.
