+	  Enable support for cards with Cologne Chip AG's HFC multiport
+	  chip. There are three types of chips that are quite similar,
+	  but the interface is different:
+	   * HFC-4S (4 S/T interfaces on one chip)
+	   * HFC-8S (8 S/T interfaces on one chip)
+	   * HFC-E1 (E1 interface for 2Mbit ISDN)

+ * module parameters:
+ * type:
+ *	By default (0), the card is automatically detected.
+ *	Or use the following combinations:
+ *	Bit 0-7   = 0x00001 = HFC-E1 (1 port)
+ * or	Bit 0-7   = 0x00004 = HFC-4S (4 ports)
+ * or	Bit 0-7   = 0x00008 = HFC-8S (8 ports)
+ *	Bit 8     = 0x00100 = uLaw (instead of aLaw)
+ *	Bit 9     = 0x00200 = Disable DTMF detect on all B-channels via hardware
+ *	Bit 10    = spare
+ *	Bit 11    = 0x00800 = Force PCM bus into slave mode. (otherwhise auto)
+ * or   Bit 12    = 0x01000 = Force PCM bus into master mode. (otherwhise auto)
+ *	Bit 13	  = spare
+ *	Bit 14    = 0x04000 = Use external ram (128K)
+ *	Bit 15    = 0x08000 = Use external ram (512K)
+ *	Bit 16    = 0x10000 = Use 64 timeslots instead of 32
+ * or	Bit 17    = 0x20000 = Use 128 timeslots instead of anything else
+ *	Bit 18    = spare
+ *	Bit 19    = 0x80000 = Send the Watchdog a Signal (Dual E1 with Watchdog)
+ * (all other bits are reserved and shall be 0)
+ *	example: 0x20204 one HFC-4S with dtmf detection and 128 timeslots on PCM
+ *		 bus (PCM master)
+ *
+ * port: (optional or required for all ports on all installed cards)
+ *	HFC-4S/HFC-8S only bits:
+ *	Bit 0	  = 0x001 = Use master clock for this S/T interface
+ *			    (ony once per chip).
+ *	Bit 1     = 0x002 = transmitter line setup (non capacitive mode)
+ *			    Don't use this unless you know what you are doing!
+ *	Bit 2     = 0x004 = Disable E-channel. (No E-channel processing)
+ *	example: 0x0001,0x0000,0x0000,0x0000 one HFC-4S with master clock
+ *		 received from port 1
+ *
+ *	HFC-E1 only bits:
+ *	Bit 0     = 0x0001 = interface: 0=copper, 1=optical
+ *	Bit 1     = 0x0002 = reserved (later for 32 B-channels transparent mode)
+ *	Bit 2     = 0x0004 = Report LOS
+ *	Bit 3     = 0x0008 = Report AIS
+ *	Bit 4     = 0x0010 = Report SLIP
+ *	Bit 5     = 0x0020 = Report RDI
+ *	Bit 8     = 0x0100 = Turn off CRC-4 Multiframe Mode, use double frame
+ *			     mode instead.
+ *	Bit 9	  = 0x0200 = Force get clock from interface, even in NT mode.
+ * or	Bit 10	  = 0x0400 = Force put clock to interface, even in TE mode.
+ *	Bit 11    = 0x0800 = Use direct RX clock for PCM sync rather than PLL.
+ *			     (E1 only)
+ *	Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0
+ *			     for default.
+ * (all other bits are reserved and shall be 0)
+ *
+ * debug:
+ *	NOTE: only one debug value must be given for all cards
+ *	enable debugging (see hfc_multi.h for debug options)
+ *
+ * poll:
+ *	NOTE: only one poll value must be given for all cards
+ *	Give the number of samples for each fifo process.
+ *	By default 128 is used. Decrease to reduce delay, increase to
+ *	reduce cpu load. If unsure, don't mess with it!
+ *	Valid is 8, 16, 32, 64, 128, 256.
+ *
+ * pcm:
+ *	NOTE: only one pcm value must be given for every card.
+ *	The PCM bus id tells the mISDNdsp module about the connected PCM bus.
+ *	By default (0), the PCM bus id is 100 for the card that is PCM master.
+ *	If multiple cards are PCM master (because they are not interconnected),
+ *	each card with PCM master will have increasing PCM id.
+ *	All PCM busses with the same ID are expected to be connected and have
+ *	common time slots slots.
+ *	Only one chip of the PCM bus must be master, the others slave.
+ *	-1 means no support of PCM bus not even.
+ *	Omit this value, if all cards are interconnected or none is connected.
+ *	If unsure, don't give this parameter.
+ *
+ * dslot:
+ *	NOTE: only one poll value must be given for every card.
+ *	Also this value must be given for non-E1 cards. If omitted, the E1
+ *	card has D-channel on time slot 16, which is default.
+ *	If 1..15 or 17..31, an alternate time slot is used for D-channel.
+ *	In this case, the application must be able to handle this.
+ *	If -1 is given, the D-channel is disabled and all 31 slots can be used
+ *	for B-channel. (only for specific applications)
+ *	If you don't know how to use it, you don't need it!
+ *
+ * iomode:
+ *	NOTE: only one mode value must be given for every card.
+ *	-> See hfc_multi.h for HFC_IO_MODE_* values
+ *	By default, the IO mode is pci memory IO (MEMIO).
+ *	Some cards requre specific IO mode, so it cannot be changed.
+ *	It may be usefull to set IO mode to register io (REGIO) to solve
+ *	PCI bridge problems.
+ *	If unsure, don't give this parameter.
+ *
+ * clockdelay_nt:
+ *	NOTE: only one clockdelay_nt value must be given once for all cards.
+ *	Give the value of the clock control register (A_ST_CLK_DLY)
+ *	of the S/T interfaces in NT mode.
+ *	This register is needed for the TBR3 certification, so don't change it.
+ *
+ * clockdelay_te:
+ *	NOTE: only one clockdelay_te value must be given once
+ *	Give the value of the clock control register (A_ST_CLK_DLY)
+ *	of the S/T interfaces in TE mode.
+ *	This register is needed for the TBR3 certification, so don't change it.
