标题: hdf框架下触摸驱动适配问题
【问题描述】
问题现象和发生的背景
开发板触摸芯片为gt9271，试着修改了input_config.hcs中的配置，成功启动触摸驱动，但是其分辨率与我在input_config.hcs里设置的不同，我设置的为1280x800，但是识别为1920x1200。

我尝试过的解决方法和结果
我尝试过更换touch_gt911.h里的firmWareParm，但没有效果。

ret = InputI2cRead(i2cClient, reg, GT_ADDR_LEN, buf, GT_CFG_INFO_LEN);
if (ret < 0) {
HDF_LOGE("%s: read chip version failed", __func__);
return HDF_FAILURE;
}

version = (buf[GT_FW_VER_HIGH] << ONE_BYTE_OFFSET) | buf[GT_FW_VER_LOW];
xSolution = (buf[GT_SOLU_X_HIGH] << ONE_BYTE_OFFSET) | buf[GT_SOLU_X_LOW];
ySolution = (buf[GT_SOLU_Y_HIGH] << ONE_BYTE_OFFSET) | buf[GT_SOLU_Y_LOW];

在哪可以将对应的配置修改？
