On October 17, 2022 thus sayeth Andrew Davis:
> Hello all,
>
> This series goes through the AM64x dtsi and disables the set of nodes
> that are not functional without additional board level information.
> This is usually pinmux data, but can also be inernal device resources.
>
> Only when the node is completed in the board file should the node be
> enabled. This helps prevents nodes that represent IP that are not
> pinned-out on a given board from being left enabled.
>
> This also reduces the effort needed to add a new board, one no longer
> needs to manually disable all the extra IP. For instance TI J784s4 has
> 20(!) MCAN instances. It is much easier to enable the one you pin out,
> vs disabling the 19 that you did not.

I wholeheartedly agree! This looks great to me!
