32 * module parameters:
33 * type:
34 * By default (0), the card is automatically detected.
35 * Or use the following combinations:
36 * Bit 0-7 = 0x00001 = HFC-E1 (1 port)
37 * or Bit 0-7 = 0x00004 = HFC-4S (4 ports)
38 * or Bit 0-7 = 0x00008 = HFC-8S (8 ports)
39 * Bit 8 = 0x00100 = uLaw (instead of aLaw)
40 * Bit 9 = 0x00200 = Disable DTMF detect on all B-channels via hardware
41 * Bit 10 = spare
42 * Bit 11 = 0x00800 = Force PCM bus into slave mode. (otherwhise auto)
43 * or Bit 12 = 0x01000 = Force PCM bus into master mode. (otherwhise auto)
44 * Bit 13 = spare
45 * Bit 14 = 0x04000 = Use external ram (128K)
46 * Bit 15 = 0x08000 = Use external ram (512K)
47 * Bit 16 = 0x10000 = Use 64 timeslots instead of 32
48 * or Bit 17 = 0x20000 = Use 128 timeslots instead of anything else
49 * Bit 18 = spare
50 * Bit 19 = 0x80000 = Send the Watchdog a Signal (Dual E1 with Watchdog)
51 * (all other bits are reserved and shall be 0)
52 * example: 0x20204 one HFC-4S with dtmf detection and 128 timeslots on PCM
53 * bus (PCM master)
54 *
55 * port: (optional or required for all ports on all installed cards)
56 * HFC-4S/HFC-8S only bits:
57 * Bit 0 = 0x001 = Use master clock for this S/T interface
58 * (ony once per chip).
59 * Bit 1 = 0x002 = transmitter line setup (non capacitive mode)
60 * Don't use this unless you know what you are doing!
61 * Bit 2 = 0x004 = Disable E-channel. (No E-channel processing)
62 * example: 0x0001,0x0000,0x0000,0x0000 one HFC-4S with master clock
63 * received from port 1
64 *
65 * HFC-E1 only bits:
66 * Bit 0 = 0x0001 = interface: 0=copper, 1=optical
67 * Bit 1 = 0x0002 = reserved (later for 32 B-channels transparent mode)
68 * Bit 2 = 0x0004 = Report LOS
69 * Bit 3 = 0x0008 = Report AIS
70 * Bit 4 = 0x0010 = Report SLIP
71 * Bit 5 = 0x0020 = Report RDI
72 * Bit 8 = 0x0100 = Turn off CRC-4 Multiframe Mode, use double frame
73 * mode instead.
74 * Bit 9 = 0x0200 = Force get clock from interface, even in NT mode.
75 * or Bit 10 = 0x0400 = Force put clock to interface, even in TE mode.
76 * Bit 11 = 0x0800 = Use direct RX clock for PCM sync rather than PLL.
77 * (E1 only)
78 * Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0
79 * for default.
80 * (all other bits are reserved and shall be 0)
81 *
82 * debug:
83 * NOTE: only one debug value must be given for all cards
84 * enable debugging (see hfc_multi.h for debug options)
85 *
86 * poll:
87 * NOTE: only one poll value must be given for all cards
88 * Give the number of samples for each fifo process.
89 * By default 128 is used. Decrease to reduce delay, increase to
90 * reduce cpu load. If unsure, don't mess with it!
91 * Valid is 8, 16, 32, 64, 128, 256.
92 *
93 * pcm:
94 * NOTE: only one pcm value must be given for every card.
95 * The PCM bus id tells the mISDNdsp module about the connected PCM bus.
96 * By default (0), the PCM bus id is 100 for the card that is PCM master.
97 * If multiple cards are PCM master (because they are not interconnected),
98 * each card with PCM master will have increasing PCM id.
99 * All PCM busses with the same ID are expected to be connected and have
100 * common time slots slots.
101 * Only one chip of the PCM bus must be master, the others slave.
102 * -1 means no support of PCM bus not even.
103 * Omit this value, if all cards are interconnected or none is connected.
104 * If unsure, don't give this parameter.
105 *
106 * dmask and bmask:
107 * NOTE: One dmask value must be given for every HFC-E1 card.
108 * If omitted, the E1 card has D-channel on time slot 16, which is default.
109 * dmask is a 32 bit mask. The bit must be set for an alternate time slot.
110 * If multiple bits are set, multiple virtual card fragments are created.
111 * For each bit set, a bmask value must be given. Each bit on the bmask
112 * value stands for a B-channel. The bmask may not overlap with dmask or
113 * with other bmask values for that card.
114 * Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000
115 * This will create one fragment with D-channel on slot 1 with
116 * B-channels on slots 2..15, and a second fragment with D-channel
117 * on slot 17 with B-channels on slot 18..31. Slot 16 is unused.
118 * If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will
119 * not function.
120 * Example: dmask=0x00000001 bmask=0xfffffffe
121 * This will create a port with all 31 usable timeslots as
122 * B-channels.
123 * If no bits are set on bmask, no B-channel is created for that fragment.
124 * Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask)
125 * This will create 31 ports with one D-channel only.
126 * If you don't know how to use it, you don't need it!
127 *
128 * iomode:
129 * NOTE: only one mode value must be given for every card.
130 * -> See hfc_multi.h for HFC_IO_MODE_* values
131 * By default, the IO mode is pci memory IO (MEMIO).
132 * Some cards require specific IO mode, so it cannot be changed.
133 * It may be useful to set IO mode to register io (REGIO) to solve
134 * PCI bridge problems.
135 * If unsure, don't give this parameter.
136 *
137 * clockdelay_nt:
138 * NOTE: only one clockdelay_nt value must be given once for all cards.
139 * Give the value of the clock control register (A_ST_CLK_DLY)
140 * of the S/T interfaces in NT mode.
141 * This register is needed for the TBR3 certification, so don't change it.
142 *
143 * clockdelay_te:
144 * NOTE: only one clockdelay_te value must be given once
145 * Give the value of the clock control register (A_ST_CLK_DLY)
146 * of the S/T interfaces in TE mode.
147 * This register is needed for the TBR3 certification, so don't change it.
148 *
149 * clock:
150 * NOTE: only one clock value must be given once
151 * Selects interface with clock source for mISDN and applications.
152 * Set to card number starting with 1. Set to -1 to disable.
153 * By default, the first card is used as clock source.
154 *
155 * hwid:
156 * NOTE: only one hwid value must be given once
157 * Enable special embedded devices with XHFC controllers.
