Hello Guenter,

Are there any other issues preventing this patches from being merged?

My major problem/concern is the interrupt handling and the repeated
restart of the hardware timer with continuously reduced timeouts.
This appears fragile, and it doesn't really make sense from a system
level point of view. Unfortunately, I don't have a data sheet for
the chip, nor the means or the time to test it myself. So we are pretty
much in limbo, unless someone from Broadcom confirms that, yes, this is
the one and expected means to program this watchdog.

Guenter

Regards,
Álvaro.

Hi Simon,

can you please re-send the entire series, with all Acked-by:/Reviewed-by:
tags as appropriate ?

Thanks,
