 * $Log: drv.c,v $
 * Revision 1.9  2004/02/24 05:55:04  reinelt
 *
 * X11 driver ported
 *
 * Revision 1.8  2004/02/15 21:43:43  reinelt
 * T6963 driver nearly finished
 * framework for graphic displays done
 * i2c_sensors patch from Xavier
 * some more old generation files removed
 *
 * Revision 1.7  2004/02/15 08:22:47  reinelt
 * ported USBLCD driver to NextGeneration
 * added drv_M50530.c (I forgot yesterday, sorry)
 * removed old drivers M50530.c and USBLCD.c
 *
 * Revision 1.6  2004/02/14 11:56:17  reinelt
 * M50530 driver ported
 * changed lots of 'char' to 'unsigned char'
 *
 * Revision 1.5  2004/01/27 06:34:14  reinelt
 * Cwlinux driver portet to NextGeneration (compiles, but not tested!)
 *
 * Revision 1.4  2004/01/21 12:36:19  reinelt
 * Crystalfontz NextGeneration driver added
 *
 * Revision 1.3  2004/01/20 15:32:49  reinelt
 * first version of Next Generation HD44780 (untested! but it compiles...)
 * some cleanup in the other drivers
 *
 * Revision 1.2  2004/01/10 10:20:22  reinelt
 * new MatrixOrbital changes
 *
 * Revision 1.1  2004/01/09 17:03:07  reinelt
 * initiated transfer to new driver architecture
 * new file 'drv.c' will someday replace 'display.c'
 * new file 'drv_MatrixOrbital.c' will replace 'MatrixOrbital.c'
 * due to this 'soft' transfer lcd4linux should stay usable during the switch
 * (at least I hope so)
 *
