Linux kernel Fusion触摸屏设备树编译错误

我正在尝试在基于IMX6的SoC上启用Fusion F07A-0114-01触摸屏。我遵循了天马触摸屏的模板：

#include "imx6q-mercury.dtsi"
/ {
    model = "AAA Mercury";
    compatible = "aaa,imx6q-hydra13", "aaa,imx6q-mercury",
                    "aaa,imx6q-hydra", "fsl,imx6q";
};

&ssd_touch {
    status = "okay";
};

其中，imx6q-mercury.dtsi中定义了ssd_touch：

&i2c1 {
    status = "okay";
    clock-frequency = <250000>;
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_i2c1_mercury
            &pinctrl_touch_mercury>;

    ssd_touch: touch@0x48 {
        /* SSD touch panel */
        compatible = "ssd254x-ts";
        reg = <0x48>;
        interrupt-parent = <&gpio7>;
        interrupts = <12 IRQ_TYPE_LEVEL_LOW>;
        rst-gpio = <&gpio6 2 GPIO_ACTIVE_HIGH>;
        xres = <1024>;
        yres = <600>;
        status = "disabled";
        /* set up for an SSD2543QN4 in the TIANMA

    };
};

其中，imx6q-mercury7.dtsi中定义了fusion_touch：

&i2c1 {
    status = "okay";
    clock-frequency = <100000>;
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_i2c1_mercury
            &pinctrl_touch_mercury>;

    fusion_touch {
        compatible = "fusion-ts";
        reg = <0x10>;
        interrupts-extended = <&gpio7 12 IRQ_TYPE_EDGE_RISING>;
        resets = <&fusion_reset>;
    };
};

&i2c1{
status=“好”；
时钟频率=；
pinctrl names=“默认”；
pinctrl-0=；
融合触摸{
compatible=“fusion ts”；
reg=；
中断扩展=；
重置=；
};
};

我在编译过程中遇到错误： DTC arch/arm/boot/dts/imx6q-hydra0F.dtb 错误：/android/vendor/nxp opensource/kernel\u imx/arch/arm/boot/dts/imx6q-hydra0F.dts:23.1-12标签或路径未找到 致命错误：分析输入树时出现语法错误

---

如何解释这一特殊错误？两者之间的区别只是ssd_touch已完全定义。

我看不出您发布的代码中包含了imx6-mercury7.dtsi。引用

&fusion\u touch

的文件包含文件imx6q-mercury7.dtsi。也许是一个简单的打字错误？我在帖子中纠正了这个错误。没有imx6-mercury.dtsi，只有imx6q-mercury.dtsi。我认为问题在于

&fusion\u-touch

不是有效的参考，因为

fusion\u-touch

不是标签，而是（相对）节点名。按照与

ssd\u touch

相同的模板，您可以将节点名称和标签更改为

fusion\u touch：touch@10{

（对于

ssd\u触摸屏：touch@0x48{

我认为将

0x

前缀放在地址中是不可取的。）

&i2c1 {
    status = "okay";
    clock-frequency = <100000>;
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_i2c1_mercury
            &pinctrl_touch_mercury>;

    fusion_touch {
        compatible = "fusion-ts";
        reg = <0x10>;
        interrupts-extended = <&gpio7 12 IRQ_TYPE_EDGE_RISING>;
        resets = <&fusion_reset>;
    };
};
