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