| 4 | Subject: [PATCH 37/47] MIPS: ath79: use correct IRQ number for the OHCI controller on AR7240 |
| 5 | |
| 6 | The currently assigned IRQ number to the OHCI |
| 7 | controller is incorrect for the AR7240 SoC, and |
| 8 | that leads to the following error message from |
| 9 | the OHCI driver: |
| 10 | |
| 11 | ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver |
| 12 | ath79-ohci ath79-ohci: Atheros built-in OHCI controller |
| 13 | ath79-ohci ath79-ohci: new USB bus registered, assigned bus number 1 |
| 14 | ath79-ohci ath79-ohci: irq 14, io mem 0x1b000000 |
| 15 | hub 1-0:1.0: USB hub found |
| 16 | hub 1-0:1.0: 1 port detected |
| 17 | usb 1-1: new full-speed USB device number 2 using ath79-ohci |
| 18 | ath79-ohci ath79-ohci: Unlink after no-IRQ? Controller is probably using the wrong IRQ. |
| 19 | |
| 20 | Fix this by using the correct IRQ number. |
