打开 lichee/linux-3.10/drivers/video/sunxi/disp/disp/disp_sys_intf.c 看了一下
int disp_sys_gpio_set_value(u32 p_handler,
u32 value_to_gpio, const char *gpio_name)
{
if (p_handler)
#ifdef CONFIG_IO_EXPAND
gpio_set_value_cansleep(p_handler, value_to_gpio);
#else
__gpio_set_value(p_handler, value_to_gpio);
#endif
else
__wrn("GPIO_DevWRITE_ONEPIN_DATA, hdl is NULL\n");
return 0;
}感觉是 CONFIG_IO_EXPAND 这个宏的问题
