Hello everybody
I was looking into an issue with the omap-wdt.c. The watchdog driver not is
reporting a different boot status when a reset is being triggered by the
watchdog.
From what I gathered, the issue is that in the omap_wdt_probe function,
pdev->dev->platform_data requires to be a reference to the PRM module,
however it has not been set, and I was wondering how this should work in
an environment that uses the device tree method. (Link to usage:
http://lxr.free-electrons.com/source/drivers/watchdog/omap_wdt.c#L268[1] ).
My questions are as follows:
1) Is my assertion correct that the current method does not work when
the driver is being initialised from an device tree instead of a old style
board file.
I think you are correct.
2) If that is the case, what would be the best method of fixing this situation.
I am not a devicetree expert, but you may have to define a property to point to
the register and bit providing the necessary information. This could possibly
be done with syscon, but I really don't know enough about it to really know for
sure what the best approach would be.
