Do _not_ use isa_virt_to_phys() even though it does the same -thing. The reason for this is that the function isa_virt_to_phys() +API. Do _not_ use isa_virt_to_bus() even though it does the same +thing. The reason for this is that the function isa_virt_to_bus() will require a Kconfig dependency to ISA, not just ISA_DMA_API which is really all you need. Remember that even though the DMA controller has its origins in ISA it is used elsewhere.
