思路：key键按下休眠唤醒直接修改zc_wake_flag标志位，休眠时直接屏蔽USB触摸屏上报事件如：gpio-keys { compatible = "gpio-keys"; autorepeat; pinctrl-names = "default"; pinctrl-0 = key_gpio; key1 { debounce-interval = 50; gpios = gpio4 RK_PA6 GPIO_ACTIVE_HIGH; label = "GPIO Key_power"; linux,code = KEY_POWER; wakeup-source; };};key驱动EV_KEY事件button-code就是KEY_POWER的对应值/
