What about the wd_timer3? It is in the audio backend, and I'm not sure
who will use it, but it does exist.
As you mentioned, wd_timer3 in OMAP4 is an IVA3 watchdog timer.
Also the current watchdog driver (omap_wdt.c) does not support more than one
watchdog timer. To add this support we need to first redesign the driver code
and then add wd_timer3 to the database.
This patch series is intended to make watchdog driver to use omap_hwmod APIs
and PM runtime APIs. Driver modification to support more than one watchdog
timers can be taken up as a separate activity later.
No necessarily, even if you do not manage this watchdog, we do need to
expose its hwmod in order to allow dspbridge/syslink to potentially
enable or disable it.
Maybe, it should be up to syslink people to do that then.
In that case, please add comment in the DB to explain that we do have
other instances but they are not managed yet.
Thanks,
Benoit
