请问LCD power 和lcd reset信号是那个GPIO控制的？
/* GPF15 = LCD backlight control
* GPF13 => Panel power
* GPN5 = LCD nRESET signal
* PWM_TOUT1 => backlight brightness
*/
static void mini6410_lcd_power_set(struct plat_lcd_data *pd,
unsigned int power)
{
if (power) {
gpio_direction_output(S3C64XX_GPF(13), 1);
gpio_direction_output(S3C64XX_GPF(15), 1);
/* fire nRESET on power up */
gpio_direction_output(S3C64XX_GPN(5), 0);
msleep(10);
gpio_direction_output(S3C64XX_GPN(5), 1);
msleep(1);
} else {
gpio_direction_output(S3C64XX_GPF(15), 0);
gpio_direction_output(S3C64XX_GPF(13), 0);
}
}
GPF15 13 还有GPN5 我看芯片手册没有找到答案。
