Greetings,
Now I am trying to turn on the LCD backlight on Assabet board, however,
I don't know how to achieve this.
In /video/sa1100fb.c, there is a function of
sa1100fb_enable_lcd_controller (), and it contains the following
routines.
if (machine_is_assabet()) {
#ifdef CONFIG_SA1100_ASSABET
BCR_set(BCR_LCD_ON);
#endif
} else if (machine_is_penny()) {
#ifdef CONFIG_SA1100_PENNY
FpgaLcdCS1 = 0x0FF; /* LCD Backlight to 100%
*/
FpgaPortI |= LCD_ON; /* Turn on LCD Backlight
*/
#endif
} else if (machine_is_tifon()) {
GPCR = GPIO_GPIO(24); /* cycle on/off-switch
*/
udelay(150);
GPSR = GPIO_GPIO(24); /* turn on display */
As you can see, LCD backlight seems to work in the case of PENNY, but
Assabet does not. (Am I right?) What can I do for turning on LCD
backlight? Any ideas?
