msn8953 触摸地址假设配置不正确，会进入驱动probe 函数吗

[码上就好hkx]

@carl.xu 解决了吗？是什么原因？

[carl.xu]

正在使用公板代码测试

[melo_fang]

probe没有执行应该只有两种可能：
一是device侧资源没有准备好，这里认为就是你这个设备树节点信息没有被正确获取到
二是driver侧驱动没有准备好，认为是config文件没配置到

确定：如果 msm 8953 的TP的i2c地址出错时， [ 5.801271] <<GTP-INF>>[gt1x_ts_probe:625] GTP Driver Version: V1.4<2015/07/10> [ 5.801274] <<GTP-INF>>[gt1x_ts_probe:626] GTP I2C Address: 0x66 会进入 probe函数

[yoveldf]

跟下init函数看下

[carl.xu]

我的理解，只要 msm 8953 dts中的 compatible = "goodix,gt9xx"; 与 static struct of_device_id goodix_match_table[] = { { .compatible = "goodix,gt9xx", }, { }, }; 匹配就应该进去

[yoveldf]

static int __init tlsc6x_init(void) { tlsc_info("%s: ++\n", __func__); return i2c_add_driver(&tlsc6x_driver); } 是的 一般来讲就是这样 ，现在你那执行了init函数 没进probe函数吗？

[melo_fang]

地址设置不对只会出现init失败然后返回，probe函数是一定会进的
