Subject: [PATCH 00/10] AM64x Disable Incomplete DT Nodes

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.

Thanks,
Andrew
