Apologies for the delay, still catching up on binding review.
I'm not entirely sure on this. The property described is still true for
the device, even if the kernel's not using that information now. My
feeling would be to keep them, unless there's a plan to better describe
the properties of the XOR channels.
It shouldn't harm the kernel to have some properties we don't use at
this point in time. If we want to reorganise the binding, the first step
would be to make the properties as deprecated, rather than removing them
outright.
Thanks,
Mark.
