* $Log: drv.c,v $
* 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)
*

* drv_query (int *rows, int *cols, int *xres, int *yres, int *bars, int *gpos)
