Sascha Hauer	ceeeb99cd8	dmaengine: mxs: rename custom flag ... The mxs dma driver uses the flags parameter in dmaengine_prep_slave_sg() for custom flags, but still uses the dmaengine specific names of the flags. Do a little bit better and at least give the flag a custom name.

Sascha Hauer	e0ddaab768	dmaengine: mxs: Add header file to be shared with gpmi nand driver ... The mxs dma driver can do PIO transfers. A pointer to the PIO words to transfer is passed in the struct scatterlist * argument of dmaengine_prep_slave_sg(). It's quite ugly and non obvious to cast u32 * to struct scatterlist * each time when calling dmaengine_prep_slave_sg(), so add a static inline wrapper function to be called by the user along with a description what is going on.
