Take a look at your system.h file. It will have the a section for each device in the system. These are the definitions you need to use when referencing your peripherals.

For LCD it gives me the following:

# define LCD_NAME "/dev/lcd"

# define LCD_TYPE "altera_avalon_lcd_16207"

# define LCD_BASE 0x00000090

# define LCD_SPAN 16

# define ALT_MODULE_CLASS_lcd altera_avalon_lcd_16207

not sure how these could be used.
