db410c doesn't ship with a bootloader that is capable of applying a dtbo though, so this conversion mandates an updated or chainloaded bootloader or out-of-tree kernel patch to support.
__adding__ is fine but, converting implies imposes a new requirement on the bootchain.
Perhaps a middle road solution is to
- Add, not convert a standalone dtbo or - Add a dtbo that includes the mezzanine dts but amends it
Option 2 for preference but, I'm not sure the dts syntax can be meaningfully made to do that.
