OK, then I will move irq/mem resource stuff to the DAI driver and dma resource stuff to the DMA driver.
Either is fine - do whatever makes most sense for your system.
OTOH, I want to keep arch code as is. There are some TXx9 SoC variations and they can have different baseaddr/irq/dma. I want to leave these details in arch code and make ASoC drivers generic as possible.
This is the common situation for SoC CPUs - most silicon vendors reuse the same IPs in diffierent combinations on different CPUs. The normal approach is to have the generic code for each SoC set up the resources for the devices that are present on that particular SoC. This avoids the need for each board using the SoC to have to replicate the information.
