You can put the board rate etc in the stdout-patch. Something like:

                stdout-path = "serial0:115200n8";

Documentation/leds/leds-class.txt says:

LED Device Naming

Is currently of the form:

"devicename:colour:function"

This all looks sensible, if a bit mixed up. Lets discuss the switch
issue in a different thread.

Documentation/devicetree/bindings/mtd/partition.txt says the
partitions should be placed under a partitions node. There are some
conditions when that does not work. So please try it, and if it does
not, ignore my comment...

Ah, this is missing from your DSA node. You can then add:

reset-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>;

inside the switch at 0 node.

This can go into the .dtsi file your previous patch added.

Nice to see the comment.
