Description

版型：rp-box-rk3568

系统：buildroor

需求：休眠唤醒

尝试操作：
1.rk3568.dtsi中默认包含了RKPM_GPIO_WAKEUP_EN (GPIO0的唤醒)。添加RKPM_GPIO_WAKEUP_EN之后

2.在sdk中rk3568-linux.dtsi中设置了使能

3.系统可以在配置echo mem >sys/power/state的10s后自动恢复，根据GPIO的配置说明

4.将gpio0b6设置为WAKEUP的key

5.通过echo mem > /sys/power/state 使系统休眠后，按键唤醒无效果，通过读取GPIO0_B6的值可以看到gpio的输入是有改变的
