项目场景：
点击2-3次power键才能唤醒屏幕。
1.gpio 占用，目测最有可能的是gpio占用 导致超时 （1.通过添加log定位 2.排查添加的gpio）-排除，没有报错也无法唤醒
2.休眠有问题
3.唤醒有问题
4.pmi休眠唤醒异常导致 --对比另外的项目有同样报错没有问题，排除
5.发现oom (PASR关闭测试)–关闭仍然出现
6.调试DP导致的（fusb302）-- 移除依然出现
7.pci
8.对比代码发现audio有所不一样，移除查看
9.按键上报延时或者没有报上去导致的
要么系统没有被唤醒，要么就是屏幕这块休眠唤醒有问题

原因分析：
1.通过echo 8 > /proc/sysrq-trigger
log发现可能是gpio被占用导致（invalid GPIO -2），经修改，排除gpio导致，没有打印此log依然出现多次点击才能唤醒的现象
