遇到点小插曲，由于厂家那边给GT911固化错了配置（把800*480分辨率搞成了1024*600），所以找厂家要了一份正确配置，需要ctp驱动中开启自动更新配置。
另外，tina linux驱动文件夹gt9xxnew中，分析gtp_init_panel初始化函数。因为手头这个屏幕与文件的都不同，并且看到源文件注释掉了从屏幕读取id。所以可确定sensor_id恒为0，那么就很简单了，自己的配置直接写到gt9xx.h的GOURP1即可。

dprintk(DEBUG_INIT, "CTP name : %s\n", config_info.name);
if (!strcmp(config_info.name, "gt9271_mb976a9")) {
sensor_id = 0;
dprintk(DEBUG_INIT, "gt9xx:sensor_id = %d\n", sensor_id);

GTP_INFO( "CTP_CONFIG_GROUP%d used, config length: %d\n", sensor_id + 1, ts->gtp_cfg_len);gt9xx.h中需增加配置：

TODO：以后再尝试把group配置放到dts中，会不会更优雅些？
