52 The first cell represents a phandle to dmac
53 The second cell specifies the encoded MID/RID values of the SSI port
54 connected to the DMA client and the slave channel configuration
56 bits[0:9] - Specifies MID/RID value of a SSI channel as below
57 MID/RID value of SSI rx0 = 0x256
58 MID/RID value of SSI tx0 = 0x255
59 MID/RID value of SSI rx1 = 0x25a
60 MID/RID value of SSI tx1 = 0x259
61 MID/RID value of SSI rt2 = 0x25f
62 MID/RID value of SSI rx3 = 0x262
63 MID/RID value of SSI tx3 = 0x261
64 bit[10] - HIEN = 1, Detects a request in response to the rising edge
66 bit[11] - LVL = 0, Detects based on the edge
67 bits[12:14] - AM = 2, Bus cycle mode
68 bit[15] - TM = 0, Single transfer mode
