From fe0cc1327ddfb69b171102019a8148a9c8b352b8 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Wed, 28 Mar 2012 11:00:19 +0200 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.
