MEDIATEK USB

[Mori Hiroki]

Hi.

I try to use USB at RT3550. But it not work.

I use rt3552.dtsi base file. I have question why irq is different from dtsi define that is 18. 

ehci0: <MTK USB 2.0 Controller> mem 0x101c0000-0x101c0fff irq 3 on ofwbus0
usbus0: EHCI version 0.10
usbus0: stop timeout
usbus0: reset timeout
usbus0: reset timeout
ehci0: USB init failed err=18
unknown: stop timeout
unknown: reset timeout
device_attach: ehci0 attach returned 6
ohci0: <MTK USB Controller> mem 0x101c1000-0x101c1fff irq 4 on ofwbus0
usbus0 on ohci0
ohci0: usbpf: Attached

If you have advice please let me know.

Thanks
