For instance, with the exception of the 16-bit - * interrupt register (IRQ#85, for reference), all of the registers are 32-bit. - * - * The big difference, however, is the lack of device-requested DMA. All modes - * are dual address transfer, and there is no 'device' setup or direction bit. - * You can DMA between a device and memory, between memory and memory, or even between - * two devices directly, with any combination of incrementing and non-incrementing - * addresses you choose. This puts a crimp in distinguishing between the 'device - * address' set up by set_dma_device_addr. - * - * Therefore, there are two options. One is to use set_dma_addr and set_dma_device_addr, - * which will act exactly as above in -- it will look to see if the source is set to - * autoincrement, and if so it will make the source use the set_dma_addr value and the - * destination the set_dma_device_addr value. Otherwise the source will be set to the - * set_dma_device_addr value and the destination will get the set_dma_addr value. - * - * The other is to use the provided set_dma_src_addr and set_dma_dest_addr functions - * and make it explicit. Depending on what you're doing, one of these two should work - * for you, but don't mix them in the same transfer setup. - */ - -/* enable/disable a specific DMA channel */ -static __inline__ void enable_dma(unsigned int dmanr) -{ - volatile unsigned int *dmalp; - -#ifdef DMA_DEBUG - printk("enable_dma(dmanr=%d)\n", dmanr); -#endif - - dmalp = (unsigned int *) dma_base_addr[dmanr]; - dmalp[MCFDMA_DMR] |= MCFDMA_DMR_EN; -} - -static __inline__ void disable_dma(unsigned int dmanr) -{ - volatile unsigned int *dmalp; - -#ifdef DMA_DEBUG - printk("disable_dma(dmanr=%d)\n", dmanr); -#endif - - dmalp = (unsigned int *) dma_base_addr[dmanr]; - - /* Turn off external requests, and stop any DMA in progress */ - dmalp[MCFDMA_DMR] &= ~MCFDMA_DMR_EN; - dmalp[MCFDMA_DMR] |= MCFDMA_DMR_RESET; -} - -/* - * Clear the 'DMA Pointer Flip Flop'. - * Write 0 for LSB/MSB, 1 for MSB/LSB access. - * Use this once to initialize the FF to a known state. - * After that, keep track of it. :-) - * --- In order to do that, the DMA routines below should --- - * --- only be used while interrupts are disabled! --- - * - * This is a NOP for ColdFire.
