|
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.
