19 The first cell is the unique device channel number as indicated by this
20 table for DB8500 which is the only ASIC known to use DMA40:
32 10: Multi-Channel Display Engine MCDE RX
42 20: SLIMbus or HSI channel 0
43 21: SLIMbus or HSI channel 1
44 22: SLIMbus or HSI channel 2
45 23: SLIMbus or HSI channel 3
53 31: MSP port 0 or SLIMbus channel 0
68 46: SLIMbus channel 8 or Multimedia DSP SXA6
69 47: SLIMbus channel 9 or Multimedia DSP SXA7
74 52: SLIMbus or HSI channel 4
75 53: SLIMbus or HSI channel 5
76 54: SLIMbus or HSI channel 6
77 55: SLIMbus or HSI channel 7
88 a fixed channel is allocated, and indicated by setting bit 3 in the
93 0x00000001 (bit 0) - mode:
94 Logical channel when unset
95 Physical channel when set
96 0x00000002 (bit 1) - direction:
99 0x00000004 (bit 2) - endianness:
102 0x00000008 (bit 3) - use fixed channel:
103 Use automatic channel selection when unset
104 Use DMA request line number when set
105 0x00000010 (bit 4) - set channel as high priority:
