The mpc8xxx_wdt driver is using two registers: SWSRR to push magic numbers, and SWCRR to control the watchdog. Both registers are available on the MPC8xx, and seem to have the same offsets and semantics as in MPC83xx/MPC86xx watchdogs. The only difference is prescale value. So this driver simply works on the MPC8xx CPUs. One quirk is needed for the MPC8xx, though. It has small prescale value and slow CPU, so the watchdog resets board prior to the driver has time to load. To solve this we should split initialization in two steps: start ping the watchdog early, and register the watchdog userspace interface later. MPC823 seem to be the first CPU in MPC8xx line, so we use fsl,mpc823-wdt compatible matching.

---help---
|
|
If you say Y here (and to one of the following options) and create a
|
|
character special file /dev/watchdog with major number 10 and minor
|
|
number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
|
|
subsequently opening the file and then failing to write to it for
|
|
longer than 1 minute will result in rebooting the machine. This
|
|
could be useful for a networked machine that needs to come back
|
|
on-line as fast as possible after a lock-up. There's both a watchdog
|
|
implementation entirely in software (which can sometimes fail to
|
|
reboot the machine) and a driver for hardware watchdog boards, which
|
|
are more robust and can also keep track of the temperature inside
|
|
your computer. For details, read
|
|
<file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
|
|
|
|
The watchdog is usually used together with the watchdog daemon
|
|
which is available from
|
|
<ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
|
|
also monitor NFS connections and can reboot the machine when the process
|
|
table is full.
|
|
|
|
If unsure, say N.

|
|
The default watchdog behaviour (which you get if you say N here) is
|
|
to stop the timer if the process managing it closes the file
|
|
/dev/watchdog. It's always remotely possible that this process might
|
|
get killed. If you say Y here, the watchdog cannot be stopped once
|
|
it has been started.

your system or have any real effect. The only way to be sure

that this driver does what you want is to make sure you

timer at IO address 0x1ee and 0x1ef. It will write to both those
