Disable USB1 导致启动卡死的问题

shenjun0818

在使用ROC-RK3399-PC 板子调试的时候，我想去掉FUSB302 这颗CC检测芯片的控制，于是我修改了"rk3399-roc-pc.dtsi" 文件：

1. &i2c4 {
   
2.         status = "okay";
   
3.         i2c-scl-rising-time-ns = <475>;
   
4.         i2c-scl-falling-time-ns = <26>;
   
5. 
   
6.         gsl3680: gsl3680@40 {
   
7.                 ..................................................
   
8.         };
   
9. 
   
10.         fusb1: fusb30x@22 {
    
11.                 compatible = "fairchild,fusb302";
    
12.                 reg = <0x22>;
    
13.                 pinctrl-names = "default";
    
14.                 pinctrl-0 = <&fusb1_int &typec1_vbus_drv>;
    
15.                 int-n-gpios = <&gpio1 1 GPIO_ACTIVE_HIGH>;
    
16.                 vbus-5v-gpios = <&gpio1 13 GPIO_ACTIVE_HIGH>;
    
17.                 -status = "okay";
    
18.                 +status = "disabled"           (okay 修改成 disabled)
    
19.         };
    
20. };
    

复制代码

结果，kernel log卡死：
