下面是设备树的配置：

ctp_twi_id = <0>;
ctp_twi_addr = <0x40>;
ctp_screen_max_x = <600>;
ctp_screen_max_y = <800>;
ctp_revert_x_flag = <0>;
ctp_revert_y_flag = <0>;
ctp_exchange_x_y_flag = <1>;

ctp_power_ldo = "none";
ctp_power_ldo_vol = <3300>;
/*ctp_power_io = <>;*/
reg=<0x40>;
};离线
错误栈都打印出来了，跟踪一下就行了，貌似都是gpio相关问题。

驱动就是这个了: drivers/input/touchscreen/silead.c
勾选 CONFIG_TOUCHSCREEN_SILEAD
配置设备树: "silead,gsl1680"

好的，我试一下，非常感谢！

勾选了CONFIG_TOUCHSCREEN_SILEAD，并配置了设备树：
gsl1680: touchscreen@40 {
compatible = "silead,gsl1680";
reg = <0x40>;
interrupt-parent = <&pio>;
interrupts = <6 10 IRQ_TYPE_EDGE_FALLING>;//PG10
/*power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>;*/
touchscreen-size-x = <600>;
touchscreen-size-y = <800>;
touchscreen-inverted-x;
touchscreen-swapped-x-y;
silead,max-fingers = <5>;
};运行后一直出现：
silead_ts 0-0040: Chip ID read error -6
我在想，驱动是内核提供的应该不会出错，那就可能是设备树部分，0x40是i2c的设备地址，但是也没有涉及到chip_id呀，有点不明白，哪里出问题了。

就是读chip id 错误, 检查硬件有没有问题, 逻辑分析仪伺候一下.

你好，我更换了一个没有问题的芯片，但是依旧是读取chip id 错误：

用逻辑分析仪吧

请问一下，现在一直打印出下面错误：
i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0
看上面的英文意思就是说I2C总线被锁定了，这可能是什么导致了，有什么解决方法？感谢
