Subsystem:
max96712 quad gmsl2 deserializer driver, media input infrastructure (v4l/dvb), open firmware and flattened device tree bindings, the rest · Maintainers:
Niklas Söderlund, Mauro Carvalho Chehab, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
From: Cosmin Tanislav <redacted> 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.
