Hi Mark,
Overall it looks very good to me, I just have one small comment.
Please don't redefine device nodes that are already defined in the
included am33xx.dtsi file (pinmux, ocp, gpmc, etc). You should just
use what is defined there instead of defining it again in your board
DT file.
Also these are IP modules that are internal details of the SoC so is
better to keep them outside of board DT files definition.
Please take a look to my am33xx cleanups series [1] to see how it
should be defined. Once you have made that changes feel free to add
my:

Benoit seems to be on holidays so please be patient with him taking your patch.
