linux - goodix 驱动程序未从 arm 设备加载

Question

我有 nanopi2-fire。我想使用 GT911 触摸屏，我把这个 goodix header file 改成这样:(第 230 -233 行)

// STEP_2(REQUIRED): Customize your I/O ports & I/O operations
#define GTP_RST_PORT    16 //16 //S5PV210_GPJ3(6)
#define GTP_INT_PORT    17  //17 //S5PV210_GPH1(3)    

这是关于 gt9xx tp 驱动程序的 s5p4418-nanopi2-common.dtsi 说它连接到 I2C0:(第 466-473 行)

goodix_ts@5d {
                compatible = "goodix,gt9xx";
                reg = <0x5d>;
                interrupt-parent = <&gpio_c>;
                interrupts = <16 IRQ_TYPE_EDGE_FALLING>;
                goodix,irq-gpio = <&gpio_c 16 0>;
};

这是 nanopi2 的 defconfig:

# CONFIG_INPUT_MOUSE is not set
CONFIG_INPUT_TOUCHSCREEN=y
CONFIG_TOUCHSCREEN_EDT_FT5X06=y
CONFIG_TOUCHSCREEN_FE_PANELS=y
CONFIG_TOUCHSCREEN_1WIRE=y
CONFIG_TOUCHSCREEN_GT9XX=y
CONFIG_TOUCHSCREEN_IT7260=y
CONFIG_TOUCHSCREEN_HIMAX=y
CONFIG_TOUCHSCREEN_ST1572=y

我认为 goodix 是默认启用的原因。当我交叉编译内核时，更改 gt9xx.h 文件并复制 zImage 和 DTB 文件 (as tutorials) 并将 SD 放入运行 Linux 后的内核没有任何变化。
我测试 i2c 它显示了这个结果:

i2cdetect -y 0
       0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:             -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- -- -- 

我认为我的设备正确连接到 i2c，但触摸不起作用。此命令也不返回任何内容:

dmesg | grep goodix

这是 dmesg 日志:

您是否在内核中启用了goodix_ts 驱动程序？在您的 dmesg 中似乎没有此类驱动程序的踪迹(还有 | grep goodix 要么没有工作，要么您发送了错误的输出)...无论如何，检查 drivers/input/touchscreen/gt9xx.c 已编译。
