- * This implements a small wrapper set to make code using the old ISA DMA API
- * work with the SH DMA API. Since most of the work in the new API happens
- * at ops->xfer() time, we simply use the various set_dma_xxx() routines to
- * fill in per-channel info, and then hand hand this off to ops->xfer() at
- * enable_dma() time.
- *
- * For channels that are doing on-demand data transfer via cascading, the
- * channel itself will still need to be configured through the new API. As
- * such, this code is meant for only the simplest of tasks (and shouldn't be
- * used in any new drivers at all).
- *
- * NOTE: ops->xfer() is the preferred way of doing things. However, there
- * are some users of the ISA DMA API that exist in common code that we
- * don't necessarily want to go out of our way to break, so we still
- * allow for some compatibility at that level. Any new code is strongly
- * advised to run far away from the ISA DMA API and use the SH DMA API
- * directly.
