- * linux/drivers/video/hecubafb.c -- FB driver for Hecuba controller
- *
- * Copyright (C) 2006, Jaya Kumar
- * This work was sponsored by CIS(M) Sdn Bhd
- *
- * This file is subject to the terms and conditions of the GNU General Public
- * License. See the file COPYING in the main directory of this archive for
- * more details.
- *
- * Layout is based on skeletonfb.c by James Simmons and Geert Uytterhoeven.
- * This work was possible because of apollo display code from E-Ink's website
- * http://support.eink.com/community
- * All information used to write this code is from public material made
- * available by E-Ink on its support site. Some commands such as 0xA4
- * were found by looping through cmd=0x00 thru 0xFF and supplying random
- * values. There are other commands that the display is capable of,
- * beyond the 5 used here but they are more complex.
- *
- * This driver is written to be used with the Hecuba display controller
- * board, and tested with the EInk 800x600 display in 1 bit mode.
- * The interface between Hecuba and the host is TTL based GPIO. The
- * GPIO requirements are 8 writable data lines and 6 lines for control.
- * Only 4 of the controls are actually used here but 6 for future use.
- * The driver requires the IO addresses for data and control GPIO at
- * load time. It is also possible to use this display with a standard
- * PC parallel port.
- *
- * General notes:
- * - User must set hecubafb_enable=1 to enable it
- * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR c2io_addr=0xIOADDR
- *
