+This patch significantly improves the reliability of high speed 
+usb writes on the bcm5354. It implements a work around for version 2
+of the usb20 core that was cribbed from the GPL sources for the 
+Asus wl500gpv2 and verified against the wl520gu sources.

+This add watchdog driver for broadcom 47xx device.
+It uses the ssb subsytem to access embeded watchdog device.
+
+Because the watchdog timeout is very short (about 2s), a soft timer is used
+to increase the watchdog period.
+
+Note : A patch for exporting the ssb_watchdog_timer_set will
+be submitted on next linux-mips merge. Without this patch it can't 
+be build as a module.

+the current ssb irq setup (in ssb_mipscore_init) have some problem :
+it configure some device on some irq without checking that the irq is not taken by an other device.
+
+For example in my case PCI host is on irq 0 and IPSEC on irq 3.
+The current code :
+- store in dev->irq that IPSEC irq is 3+2
+- do a set_irq 0->3 on PCI host
+
+But now IPSEC irq is not routed anymore to the mips code and dev->irq is wrong. This cause problem described in [1].
+
+This patch try to solve the problem by making set_irq configure the device we want to take the irq on the shared irq0.
+The previous example become :
+- store in dev->irq that IPSEC irq is 3+2
+- do a set_irq 0->3 on PCI host :
+  - irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC
+
+
+I also added some code to print the irq configuration before and after irq setup to allow easier debugging. And I add extra checking in ssb_mips_irq to report device without irq or device with not routed irq.
