staging: Add driver to support wanPMC-CxT1E1 card. 

Obviously still needs serious attention, but it compiles.

Original author: Rick Dobbs

Add driver to support wanPMC-CxT1E1 card.

This card provides 1-4 ports of T1E1 in PMC form factor.

Note, Rick doesn't want his email showing up as the "From:" author, but
has given his blessing to have the code included in the kernel tree.

config CXT1E1
tristate "SBE wanPMC-C[421]E1T1 hardware support"
depends on HDLC && PCI
---help---
This driver supports the SBE wanPMC-CxT1E1 1, 2 and 4 port T3
channelized stream WAN adapter card which contains a HDLC/Transparent
mode controller.
If you want to compile this driver as a module
say M here and read <file:Documentation/modules.txt>.
The module will be called 'cxt1e1'.
If unsure, say N.
config SBE_PMCC4_NCOMM
bool "SBE PMCC4 NCOMM support"
depends on CXT1E1
---help---
SBE supplies optional support for NCOMM products.
If you have purchased this optional support you must say Y or M
here to allow the driver to operate with the NCOMM product.

* $Log: musycc.c,v $
* Revision 2.1 2007/08/15 23:32:17 rickd
* Use 'if 0' instead of GNU comment delimeter to avoid line wrap induced compiler errors.
*
* Revision 2.0 2007/08/15 22:13:20 rickd
* Update to printf pointer %p usage and correct some UINT to ULONG for
* 64bit comptibility.
*
* Revision 1.7 2006/04/21 00:56:40 rickd
* workqueue files now prefixed with <sbecom> prefix.
*
* Revision 1.6 2005/10/27 18:54:19 rickd
* Clean out old code. Default to HDLC_FCS16, not TRANS.
*
* Revision 1.5 2005/10/17 23:55:28 rickd
* Initial port of NCOMM support patches from original work found
* in pmc_c4t1e1 as updated by NCOMM. Ref: CONFIG_SBE_PMCC4_NCOMM.
*
* Revision 1.4 2005/10/13 20:35:25 rickd
* Cleanup warning for unused <flags> variable.
*
* Revision 1.3 2005/10/13 19:19:22 rickd
* Disable redundant driver removal cleanup code.
*
* Revision 1.2 2005/10/11 18:36:16 rickd
* Clean up warning messages caused by de-implemented some <flags> associated
* with spin_lock() removals.
*
* Revision 1.1 2005/10/05 00:45:28 rickd
* Re-enable xmit on flow-controlled and full channel to fix restart hang.
* Add some temp spin-lock debug code (rld_spin_owner).
*
* Revision 1.0 2005/09/28 00:10:06 rickd
* Initial release for C4T1E1 support. Lots of transparent
* mode updates.

* Revision 2.7 2005/10/18 18:16:30 rickd
* Further NCOMM code repairs - (1) interrupt matrix usage inconsistant
* for indexing into nciInterrupt[][], code missing double parameters.
* (2) check input of ncomm interrupt registration cardID for correct
* boundary values.
*
* Revision 2.6 2005/10/17 23:55:28 rickd
* Initial port of NCOMM support patches from original work found

* How to be a proc read function
* ------------------------------
* Prototype:
* int f(char *buffer, char **start, off_t offset,
* int count, int *peof, void *dat)
*
* Assume that the buffer is "count" bytes in size.
*
* If you know you have supplied all the data you
* have, set *peof.
*
* You have three ways to return data:
* 0) Leave *start = NULL. (This is the default.)
* Put the data of the requested offset at that
* offset within the buffer. Return the number (n)
* of bytes there are from the beginning of the
* buffer up to the last byte of data. If the
* number of supplied bytes (= n - offset) is
* greater than zero and you didn't signal eof
* and the reader is prepared to take more data
* you will be called again with the requested
* offset advanced by the number of bytes
* absorbed. This interface is useful for files
* no larger than the buffer.
* 1) Set *start = an unsigned long value less than
* the buffer address but greater than zero.
* Put the data of the requested offset at the
* beginning of the buffer. Return the number of
* bytes of data placed there. If this number is
* greater than zero and you didn't signal eof
* and the reader is prepared to take more data
* you will be called again with the requested
* offset advanced by *start. This interface is
* useful when you have a large file consisting
* of a series of blocks which you want to count
* and return as wholes.
* (Hack by Paul.Russell@rustcorp.com.au)
* 2) Set *start = an address within the buffer.
* Put the data of the requested offset at *start.
* Return the number of bytes of data placed there.
* If this number is greater than zero and you
* didn't signal eof and the reader is prepared to
* take more data you will be called again with the
* requested offset advanced by the number of bytes
* absorbed.
