USB is not detected in AR9331 OlliteV1 16MB Flash

[Arun1295]

USB port is not detected in Ar9331 Atheros board.

In DTS (target/linux/ath79/dts/ar9330.dtsi )Interrupt number 3 is registered for UART as well as USB. We are suspecting this could be the reason.

usb@1b000000 {
compatible = "chipidea,usb2";
reg = <0x1b000000 0x200>;
interrupts = <0x3>;
resets = <0x5 0x5>;
reset-names = "usb-host";
phy-names = "usb-phy";
phys = <0xa>;
status = "okay";
};

uart@18020000 {
compatible = "qca,ar9330-uart";
reg = <0x18020000 0x14>;
interrupts = <0x3>;
clocks = <0x4 0x3>;
clock-names = "uart";
};
