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.
