Even if the driver was matched because of an MX23-I2C "compatible"
binding, both devicetree and runtime could provide data that it actually
runs on MX28. That shouldn't be a problem.

IIRC I mentioned that a discussion about the bindings won't make the
next merge window. That's why I proposed either module_parameter or
dropping the binding entirely as possible inbetween options.
