V853 的 USB 如何设置成开机默认 Host 模式？

[netube]

如题，每次开机都要输入一次 cat /sys/devices/platform/soc/usbc0/usb_host 实在是太麻烦了

[NULL037]

@netube 在开机自启脚本中增加命令

@null037 我试过弄成开机设置，感觉切换不了。

@fawen
board.dts 可以修改

@whycan

&usbc0 {
	device_type = "usbc0";
	usb_port_type = <0x2>;
	usb_detect_type = <0x1>;
	usb_detect_mode = <0x0>;
	usb_id_gpio     = <&pio PH 14 0 1 0xffffffff 0xffffffff>;
	/*usb_det_vbus_gpio   = <&pio PH 3 0 1 0xffffffff 0xffffffff>;*/
	usb_det_vbus_gpio = "axp_ctrl";
	det_vbus_supply = <&gpio_charger>;
	usb_regulator_io = "nocare";
	usb_wakeup_suspend = <0x0>;
	usb_luns = <0x3>;
	usb_serial_unique = <0x0>;
	usb_serial_number = "20080411";
	status = "okay";
};

是改这里吗？whycan晕哥！需要改哪个参数。

usb_port_type改成1就可以
