nozomi driver update
Minor cleanups and removal of in-file changelog: - Correction of misspellings and wrong encoded Name - changed 'unsigned' to 'unsigned int' for better readability - use of generic devicefile access macro - fixed/added explanatory comment to ntty_put_char Signed-off-by: Frank Seidel <fseidel@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

/*
|
||||
* CHANGELOG
|
||||
* Version 2.1d
|
||||
* 11-November-2007 Jiri Slaby, Frank Seidel
|
||||
* - Big rework of multicard support by Jiri
|
||||
* - Major cleanups (semaphore to mutex, endianess, no major reservation)
|
||||
* - Optimizations
|
||||
*
|
||||
* Version 2.1c
|
||||
* 30-October-2007 Frank Seidel
|
||||
* - Completed multicard support
|
||||
* - Minor cleanups
|
||||
*
|
||||
* Version 2.1b
|
||||
* 07-August-2007 Frank Seidel
|
||||
* - Minor cleanups
|
||||
* - theoretical multicard support
|
||||
*
|
||||
* Version 2.1
|
||||
* 03-July-2006 Paul Hardwick
|
||||
*
|
||||
* - Stability Improvements. Incorporated spinlock wraps patch.
|
||||
* - Updated for newer 2.6.14+ kernels (tty_buffer_request_room)
|
||||
* - using __devexit macro for tty
|
||||
*
|
||||
*
|
||||
* Version 2.0
|
||||
* 08-feb-2006 15:34:10:Ulf
|
||||
*
|
||||
* -Fixed issue when not waking up line disipine layer, could probably result
|
||||
* in better uplink performance for 2.4.
|
||||
*
|
||||
* -Fixed issue with big endian during initalization, now proper toggle flags
|
||||
* are handled between preloader and maincode.
|
||||
*
|
||||
* -Fixed flow control issue.
|
||||
*
|
||||
* -Added support for setting DTR.
|
||||
*
|
||||
* -For 2.4 kernels, removing temporary buffer that's not needed.
|
||||
*
|
||||
* -Reading CTS only for modem port (only port that supports it).
|
||||
*
|
||||
* -Return 0 in write_room instead of netative value, it's not handled in
|
||||
* upper layer.
|
||||
*
|
||||
* --------------------------------------------------------------------------
|
||||
* Version 1.0
|
||||
*
|
||||
* First version of driver, only tested with card of type F32_2.
|
||||
* Works fine with 2.4 and 2.6 kernels.
|
||||
* Driver also support big endian architecture.
