Allwinner H3/H2+ dts question - regression?

I have a NanoPi NEO (very similar to Orange Pi) working except for I2C with an older revision (325705). I haven’t been able to get it to boot without doing a “load -t dtb /boot/dtb/nanopi-neo.dtb” first. Not as lucky with current revisions.
I started with https://framkant.org/2017/07/running-freebsd-on-nanopi-neo-or-orangepi-zero/ <https://framkant.org/2017/07/running-freebsd-on-nanopi-neo-or-orangepi-zero/> and made the following changes:
u-boot-nanopi-neo/Makefile MODEL needs to be nanopi_neo (underscore instead of dash)
crochet/board/NanoPi-NEO/setup.sh SUNXIO_UBOOT needs to also be underscore instead of dash (u-boot-nanopi_neo).
Built on FreeBSD 11.1 (amd64) release.
Using current ports, these two patches were needed to get u-boot to build:

I also want to use I2C so I added this to the bottom of sys/boot/fdt/dts/arm/nanopi-neo.dts:
&i2c0 {
status = "okay";
};
&i2c1 {
status = "okay";
};
It looks ok at boot but I don’t see any I2C devices when I scan. Same hardware is showing 2 devices on Friendlyarm (manufacturer) linux. I see sys/boot/fdt/dts/arm/orangepi-plus-2e.dts has &r_i2c as well and perhaps I need that. (this stuff is definitely not my area of expertise)
