This actually brings me to an interesting idea: the s3c64xx SPI driver
is used with the regular dmaengine API and pl330 on S5P and Exynos,
but with the s3c-dma interface and pl080 on S3C64xx.
If we just convert S3C64xx to use the pl080 dmaengine driver
instead, we can apply my SPI patch without breaking anything.
We still need a solution for the ASoC drivers, but they are
not as essential. We could probably move the wrapper files
from plat-samsung/*dma*.c to sounds/soc/samsung when that becomes
the only remaining user.
There is also drivers/mmc/host/s3cmci.c, which uses the s3c-dma
interface, but it is only used on s3c24xx, not s3c64xx or later.
