设备树修改怎么修改?usb工作不正常，4g模块工作不正常。

[cnsn17]

本人对设备树一知半解。从自带安卓系统提取的设备树，对照修本改项目可用的设备树，4g模块插入mini_pcie插槽没有任何反应，测量模块vcc无电压。求助。

	xh_custom {
		status = "okay";
		compatible = "rockchip,xh_custom";

		gpio_en = <0x38 0x02 0x00>;
		gpio_0 = <0x38 0x03 0x00>;
		gpio_1 = <0x38 0x04 0x00>;
		gpio_2 = <0x38 0x05 0x00>;
		gpio_3 = <0x38 0x06 0x00>;
		backlight_en = <0x37 0x03 0x00>;
		host_otg_en = <0x37 0x1c 0x00>;
		host_hub_en = <0x18 0x1e 0x00>;
		host1_en = <0x37 0x19 0x00>;
		host2_en = <0x37 0x15 0x00>;
		host3_en = <0x37 0x1a 0x00>;
		host4_en = <0x37 0x1d 0x00>;
		host5_en = <0x37 0x1e 0x00>;
		host6_en = <0x37 0x1b 0x00>;
		xh_3g_power = <0xce 0x0a 0x00>;
		xh_3g_reset = <0xce 0x0c 0x01>;
		xh_3g_en = <0xce 0x0d 0x01>;
	};

		pmic@1b {
			compatible = "rockchip,rk808";
			reg = <0x1b>;
			interrupt-parent = <0x34>;
			interrupts = <0x15 0x08>;
			pinctrl-names = "default";
			pinctrl-0 = <0x36>;
			rockchip,system-power-controller;
			wakeup-source;
			#clock-cells = <0x01>;
			clock-output-names = "xin32k\0rk808-clkout2";
			extern_drv_gpio = <0x37 0x18 0x00>;
			hub_rst_gpio = <0x18 0x1e 0x00>;
			ap_work_gpio = <0x38 0x1c 0x00>;
			vcc1-supply = <0x39>;
			vcc2-supply = <0x39>;
			vcc3-supply = <0x39>;
			vcc4-supply = <0x39>;
			vcc6-supply = <0x39>;
			vcc7-supply = <0x39>;
			vcc8-supply = <0x3a>;
			vcc9-supply = <0x39>;
			vcc10-supply = <0x39>;
			vcc11-supply = <0x39>;
			vcc12-supply = <0x39>;
			vddio-supply = <0x3b>;
			phandle = <0xd1>;
.....

将xh_3g_power = <0xce 0x0a 0x00>; 正常上电不识别。改为以下电源节点正常上电。

	vcc3v3-pcie-regulator {
		compatible = "regulator-fixed";
		enable-active-high;
		pinctrl-names = "default";
		pinctrl-0 = <0xbc>;
		regulator-boot-on;
		regulator-always-on;
		regulator-name = "vcc3v3_pcie";
		regulator-min-microvolt = <0x325aa0>;
		regulator-max-microvolt = <0x325aa0>;
		vin-supply = <0x1e>;
		gpio = <0x25 0x0a 0x00>;
		phandle = <0x19>;
	};

还有xh_3g_reset = <0xce 0x0c 0x01>;xh_3g_en = <0xce 0x0d 0x01>和pcie节点有关吗？不知道该放在哪在哪个节点下。

出现在pmic节点下hub_rst_gpio和hub_rst_gpio ，意义不明。

尽管我一直在尝试修改，但是usb大概率没有正确移植， 已知usb-hub下的usb2供电无输出，其他正常。

以下是我的修改到目前为止的dts和安卓提取的dts。

无法正常初始化

放到led里面了,现在我理解为什么leds里面的引脚为什么对不上了，做这个机型dtb移植的把我坑惨了。
