/*.............................................................................
* Project : linux driver for Plustek parallel-port scanners
*.............................................................................
* File: plustek-pp_scandata.h - here we define the ScanData structure...
* and a lot of register settings
*.............................................................................
*
* based on sources acquired from Plustek Inc.
* Copyright (C) 1998 Plustek Inc.
* Copyright (C) 2000-2003 Gerhard Jaeger <gerhard@gjaeger.de>
* also based on the work done by Rick Bronson <rick@efn.org>
*.............................................................................
* History:
* 0.30 - initial version
* 0.31 - no changes
* 0.32 - added fWarmupNeeded to struct ScanData
* - removed function FillDataToColorTable from struct ScanData
* - removed dwLampDelay from struct ScanData
* 0.33 - cosmetic changes
* - removed PositionLamp from structure
* - added dwLastPortMode to struct ScanData
* 0.34 - removed WaitBack() function from pScanData structure
* removed wStayMaxStep from pScanData structure
* 0.35 - removed SetInitialGainRAM from pScanData structure
* changed ModelStr list
* 0.36 - added some defines for the ASIC 96001 (model 4800)
* added wDither to DataInfo structure
* removed dwPreferSize from struct ScannerCaps
* cleanup
* moved all stuff that is used by the backend and the driver
* to plustek-share.h which is in the backend directory
* added ModelOverride parameter to struct
* added strcut pardevice to struct
* 0.37 - added bIODelay for SPP/BIDI port operations
* added ReadData to struct
* added ProcDirDef
* added ButtonCount
* removed RegisterToScanner from struct
* removed MaxDpiByInterpolation from struct
* 0.38 - added function PutToIdleMode() to struct
* added function Calibration() to struct
* changed interface of the ReInitAsic() function
* major changes: moved a lot of stuff to hwdefs.h
* added IO, Device, Shade, Scan and Bufs to struct
* 0.39 - added forceMode to struct
* added f97003, b97003DarkR, b97003DarkB, b97003DarkG to struct
* 0.40 - no changes
* 0.41 - no changes
* 0.42 - no changes
