1 * Freescale Smart Direct Memory Access (SDMA) Controller for i.MX
4 - compatible : Should be "fsl,<chip>-sdma"
5 - reg : Should contain SDMA registers location and length
6 - interrupts : Should contain SDMA interrupt
7 - #dma-cells : Must be <3>.
8 The first cell specifies the DMA request/event ID. See details below
9 about the second and third cell.
10 - fsl,sdma-ram-script-name : Should contain the full path of SDMA RAM
13 The second cell of dma phandle specifies the peripheral type of DMA transfer.
14 The full ID of peripheral types can be found below.
30 12 External peripheral
31 13 Memory Stick Host Controller
32 14 Shared Memory Stick Host Controller
41 The third cell specifies the transfer priority as below.
