I think that the rational for removing properties (or not) is their
presence in the bindings as DT should describe the hardware and not the
current state of the driver implementation.
I see that 'bus-width' may be removed from the binding, as per discussion
in a different sub-thread. I'd like that discussion to reach a conclusion
before considering that part of this patch any further.
And I'd appreciate Niklas's feedback on the 'pclk-sample' portion.
