Ok, I use the "compatible" string to figure out what modules are needed.

 I have pushed up what I have to https://github.com/ljbade/linux/tree/bpi-r3-dts

There is still some work to be done, but I fixed up most of the device tree schema errors. I also just tested a freshly built .dtb file from the branch after fixing things and I still get the same boot log with the v6.10 rc3 kernel.

I did notice an interesting schema error though related to the crypto device:

arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3.dtb: crypto@10320000: interrupts: [[0, 116, 4], [0, 117, 4], [0, 118, 4], [0, 119, 4]] is too short
from schema $id: http://devicetree.org/schemas/crypto/inside-secure,safexcel.yaml#
arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3.dtb: crypto@10320000: interrupt-names: ['ring0', 'ring1', 'ring2', 'ring3'] is too short
from schema $id: http://devicetree.org/schemas/crypto/inside-secure,safexcel.yaml#

I do not know if this is related to the boot errors I am seeing or not.
