7620 Reset按键GPIO

1.在nvram_daemon.c修改如下，这个文件有点难找到

#elif defined (CONFIG_RALINK_MT7620)

-       info.irq = 44;  // MT7620 reset default

+       info.irq = 0;   // MT7620 reset default

2.在 ralink_gpio.h里面修改宏定义，根据原理图和datasheet来确定

-#define RALINK_GPIOMODE_DFT            (RALINK_GPIOMODE_I2C) | (RALINK_GPIOMODE_UARTF) | (RALINK_GPIOMODE_EPHY)

+#define RALINK_GPIOMODE_DFT            (RALINK_GPIOMODE_I2C) | (RALINK_GPIOMODE_UARTF)

3.在 ralink_gpio.c里面修改

//2<t<5

                                        printk("i=%d,2s<t<5s\n", i);

-                                       ralink_gpio_notify_user(3);

+                                       ralink_gpio_notify_user(1);

                                }

                        

-                       

-                               else if (time_before(now, record[i].falling + 2000L)) {

-                                       //less than 8s

-                                               ralink_gpio_notify_user(1);

-                                               printk("i=%d,5s<t<10s\n", i);

-                                               

-                               }

                                else {

                                        //press for several seconds

-                                       printk("i=%d, t>10s\n", i);

+                                       printk("i=%d, t>5s\n", i);

                                        ralink_gpio_notify_user(2);

                                }

                        }
