[PATCH 3/3] arm: allwinner: Wire up USB EHCI |
Date: |
Thu, 13 Feb 2020 22:21:09 -0800 |
Initialize EHCI controllers on Allwinner A10. With this patch applied,
USB EHCI ports are discovered when booting the cubieboard machine with
a recent Linux kernel.
ehci-platform 1c14000.usb: EHCI Host Controller
ehci-platform 1c14000.usb: new USB bus registered, assigned bus number 1
ehci-platform 1c14000.usb: irq 26, io mem 0x01c14000
ehci-platform 1c14000.usb: USB 2.0 started, EHCI 1.00
ehci-platform 1c1c000.usb: EHCI Host Controller
ehci-platform 1c1c000.usb: new USB bus registered, assigned bus number 2
ehci-platform 1c1c000.usb: irq 31, io mem 0x01c1c000
ehci-platform 1c1c000.usb: USB 2.0 started, EHCI 1.00
