//配置基本信息

//平台型号忘记了

//IC:NT35523

//Interface:mipi-4lane

//2power mode(NT50198B)

//不良现象：客户反馈屏点亮显异花屏，我到现场看，明显是GIP不对，摸IC还有点发烫，

//分析思路如下:先检查平台的代码与原厂给的是否一致，代码未发现问题；其次量常规电压如

//VGL,VGH,AVDD,AVEE,VCC,IOVCC发现VGL,VGH异常；那问题来了，代码没问题，送到驱动IC就异常了，

//要么屏有问题，要么平台发的代码掉链子了，试了几次屏都一个屌样，我觉得还是对屏要有信心，

//屏厂不可能这么坑，所以先要验证第二种情况，我好歹是有备而来，上逻辑分析仪，飞线抓主板下的代码，

//果然平台掉到坑里 了

//有图有真相，左边是应下的代码，右边是逻辑分析仪抓到的代码，对比过后就找到原因了

//最终平台改海思MIPI底层LP MODE的速率，编译一版烧进去，效果扛扛的，优化一下flicker收工回家。

//滴滴FAE提醒：逻辑分析出门必备神品，值得拥有。
