Why this is 2? Aliases are continues and match the board. For example
Universal calls this mmc1 and the next mmc2, not 3.

I bet it is the same on Trats and all other boards.

This is also correct.

For all other cases, where schematics are missing, just make them linear.

Not sure I follow, Universal calls sdhci_2 mmc1 in schematics? (I have tried searching for
schematics but cannot really find anything about this board)

Sure, I can change to mmc0, mmc1 for all 4210 devices.

Yes. The alias numbers are the numbering exposed on the board. This
might or might not match original numbering. If you have a development
board with a SoM, pretty often not all interfaces, let's say UARTs, are
exposed. SoM might have 10 UARTs, but board has only 4 and numbers them
UART0-3. Aliases should be 0-3, not 0, 5, 7, 9.

Yes, please.
