well this assume the new feature does not need modifying an existing
binding.
again taking the Kirkwood crypto example, the driver was written using
lets say "PIO" mode, and a patch has been posted recently that mostly
rewrite the driver to use DMA mode after.
chances are the binding written by the first developer would not be the
same at all as the second
does the "DT bindings validation team" will have to look inside SOC
datasheet and decide whether the developer described the hardware
correctly ?
In another post, someone proposed that time would tell if a binding was
"stable" enough. In that case that's not true, 2 years have passed
before someone took a glance at what the hardware could do and proposed
a different implementation.
