So Dave added upstream support for DT for D-step version of BCM2712 and the file is named bcm2712-d-rpi-5-b.dtb.

In the downstream firmware there's two files, one called the same as upstream bcm2712-d-rpi-5-b.dtb and bcm2712d0-rpi-5-b.dtb and I had assumed they were the same which the later possibly being an early naming and the later added to align with upstream, but running a dtdiff against the two downstream names and they differ with bcm2712-d-rpi-5-b.dtb actually containing c0 bits. Trying to boot on a revD with the downstream dtb that's named the same as a upstream dtb fails to boot.

Is that intended, what is the intended naming for the revD dtbs?
