The "mentor,musb" binding isn't documented so I was about to document
it.
The node is missing a few properties for configuration like
"multipoint", "dyn_fifo", "num_eps" or "ram_bits". However I am not sure
"missing" is the right word here because some of those informations
might be obtained from the chip itself but it is not done (yet).
Further the ePARP 2.3.1 says the matching goes from left to right taking
the fist match. Right now there is jus a driver for
"stericsson,db8500-musb" and none for "mentor,musb". I'm not 100% that
it is simply possible to have a generic since even for DMA we have
ifdefs in the driver between "generic mentor dma" and "ux500 dma" and I
mean within musb and not the dma code.
For that reason (that I am not sure a generic musb binding is possible and
how its binding / required properties will look like) and the reason that
we have here a minor binding without a driver to look at I suggest to
remove that binding.
If the majority of people prefer to keep this binding I'm curious how
the documentation of the binding should look like.
