[RFC PATCH v2 11/16] mmc: omap_hsmmc: limit max_segs with the EDMA DMAC

2012-10-11 Thread Matt Porter
The EDMA DMAC has a hardware limitation that prevents supporting scatter gather lists with any number of segments. Since the EDMA DMA Engine driver sets the maximum segments to 16, we do the same. TODO: this will be replaced once the DMA Engine API supports an API to query the DMAC's segment size
