I think Jassi is the right person to handle this one even though you
don't like the generic DMA APIs

1) since you become a member of linaro. it's role of linaro.
2) know the how to use the s3c-pl330 at sound (most user of DMA is
sound, SPI and MMC)
3) now you're the Samsung Sound maintainer

If we move the generic DMA APIs, it's also need to modify the its
consumer, sound and SPI.

Thank you,
