In linux kernel since version 2.6.29 (release Date: 2009-03-23)
This driver now supports any serial or parallel LCD wired to a parallel
port. But before assigning signals, the driver needs to know if it will
be driving a serial LCD or a parallel one. Serial LCDs only use 2 wires
(SDA/SCL), while parallel ones use 2 or 3 wires for the control signals
(E, RS, sometimes RW), and 4 or 8 for the data. Use 0 here for a 8 bits
parallel LCD, and 1 for a serial LCD.
