No you're right. The documentation with the bindings and the
patch to the driver...

Then just arch/arm/boot/dts/* separately.

The latter is where I have all my trouble and screwup...

(However when we break the devicetree data out of the kernel
and into its own git we will have to follow the pattern above with
a patch of bindings+DT changes and another one in parallell
changing the kernel, but that is for a more advanced age.)
