Hello,
two lines should be added in rk3328-a1.dts:
Code
vcc_host_5v: usb3-current-switch {
compatible = "regulator-fixed";
enable-active-high;
gpio = <&gpio0 RK_PA0 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&usb30_host_drv>;
regulator-name = "vcc_host_5v";
regulator-always-on;
regulator-boot-on;
vin-supply = <&vcc_sys>;
};
Display More
If regulator-always-on and regulator-boot-on are added the USB3.0 port works.
