As usual, you have to find a balance between cost vs benefits. If you look at the Device-Tree side, we don' t have many platforms requiring quirks. In particular, the DMA is so far strictly limited to a single platform (RPI). So I would be surprised if we suddenly require tons of quirks when using ACPI. Therefore I am unconvinced that such a big effort is necessary. That being said, if you have plenty of time to invest to implement a DSDT parser in a stub domain, then I would be happy to review the patches. Cheers,
