[alsa-devel] [PATCH 4/7] Alchemy: DB1200 AC97+I2S audio support.

I see now what you mean, but this is ugly as sin:
I now need to register 2 platform devices in the board code: 1 for the DAI
(with resources mmio + irq) and 1 for the DMA engine (with ddma id resources),
or register the DMA engine device from within the AC97/I2S drivers.

This is in my opinion even worse than the current scheme, which at least allows
me to group all PSC resources into one struct resource which all audio-related
drivers can share without too much uglyness.
