Linux i2c touch device driver probe not be called - linux-device-driver

Question

I try to add focaltech touch driver to my board, the fts_ts_init() is worked, but the ->probe() not be called, I do not why. CONFIG_OF is opened.
Driver code：
static const struct i2c_device_id fts_ts_id[] = {
{FTS_DRIVER_NAME, 0},
{}
};
static const struct of_device_id fts_dt_match[] = {
{.compatible = "focaltech,fts", },
{}
};
MODULE_DEVICE_TABLE(of, fts_dt_match);
static struct i2c_driver fts_ts_driver = {
.probe = fts_ts_probe,
.remove = fts_ts_remove,
.driver = {
.name = FTS_DRIVER_NAME,
.owner = THIS_MODULE,
#if defined(CONFIG_PM) && FTS_PATCH_COMERR_PM
.pm = &fts_dev_pm_ops,
#endif
.of_match_table = of_match_ptr(fts_dt_match),
},
.id_table = fts_ts_id,
};
static int __init fts_ts_init(void)
{
int ret = 0;
FTS_FUNC_ENTER();
ret = i2c_add_driver(&fts_ts_driver);
printk("[FTS_TS] ret=%d\n", ret);
if (ret)
FTS_ERROR("Focaltech touch screen driver init failed!");
FTS_FUNC_EXIT();
return ret;
}
module_init(fts_ts_init);
Device Tree Source:
i2c4: i2c#0x10054000 {
compatible = "ingenic,x2000-i2c";
reg = <0x10054000 0x1000>;
interrupt-parent = <&core_intc>;
interrupts = <IRQ_I2C4>;
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
focaltech#38{
compatible = "focaltech,fts";
reg = <0x38>;
interrupt-parent = <&gpa>;
interrupts = <3 0x2>;
focaltech,reset-gpio = <&gpa 0 GPIO_ACTIVE_LOW >;
focaltech,irq-gpio = <&gpa 3 0x2 >;
focaltech,max-touch-number = <2>;
focaltech,display-coords = <0 0 800 480>;
status = "okay";
};
};
I try to write the node in /, and use a simple paltform drvier, of_match_table is the same, ->probe() is called.
