which DMA channel is used by AM335X GPMC?



hi:

I want to confirm which DMA channel the AM335x GPMC is using under the Linux 3.2.0 PSP.

in file "...plat/dma.h", we know that channel 4 is for the GPMC for OMAP2

#define OMAP24XX_DMA_GPMC 4 /* S_DMA_3 */

in file "plat/dma-33xx.h", there is a macro:

#define AM33XX_DMA_GPM 52

is that channel 52 is used for the GPMC for AM335X?
