To be precise, the problem is that only half of the device tree files were synced. am33xx.dtsi (and seemingly some more) were skipped, leading to the symptoms you found. I think it is likely that the upstream changes in am33xx.dtsi which we are missing right now will lead to more regressions of similar nature.
So I'd say we should dig deeper into the problems you encountered while attempting to just sync the entirety of am33xx.dtsi. The end goal is that all device-tree files not ending in `-uboot` match what is in Linux, so it is inevitable that someone needs to look into this anyway.
