ARM: S3C24XX: claim spi channels for hsspi in dma-s3c2443
SoCs starting with the S3C2443 contain SPI controllers compatible with the
spi-s3c64xx driver and therefore need separate dma channels for rx and tx.
This patch introduces dma channel declarations for these and changes the
dma-s3c2443.c accordingly.
None of the older SoCs use the spi-dma at all. Most boards bitbang their
spi use and the spi-s3c24xx driver also does not use the dma system.
