This is a point where the DT and mmc maintainers have a continual
misunderstanding of the facts.
There were requests to discuss the binding as far back as 2012:
https://www.linux-mips.org/archives/linux-mips/2012-05/msg00119.html
They were met with silence.
The firmware containing these bindings is out in the wild. If we
deprecate some of the bindings, the driver will still have to support
them in the future.
In the case of OCTEON based devices, the device tree bindings are a
firmware <--> kernel ABI as the device trees always come from the
firmware and not some other place.
