I believe, packet mode is already supported in the current DMA driver.
Both the FS and BS bits of the CCR are set when packet mode is
selected. This is because, enum for OMAP_DMA_SYNC_PACKET is '0x03'
(i.e OMAP_DMA_SYNC_FRAME | OMAP_DMA_SYNC_BLOCK).

System DMA packet synchronisation is currently not supported in the
Linux Kernel.
This patch provides necessary modifications to support packet
synchronisation:
Function omap_set_dma_transfer_params() handles value OMAP_DMA_SYNC_PACKET
to program FS and BS bits of register CCR.
Users can give the p
