int
-dma_supported(struct device *dev, u64 mask)
-
-Checks to see if the device can support DMA to the memory described by
-mask.
-
-Returns: 1 if it can and 0 if it can't.
-
-Notes: This routine merely tests to see if the mask is possible. It
-won't change the current mask settings. It is more intended as an
-internal API for use by the platform than an external API for use by
-driver writers.
