Soekris net5501 - how to use hardware watchdog?

Hi all,

what modules to kernel should I load in order to make use of hardware watchdog installed in Soekris net5501 ? 

AFAIK it is located in CS5536 chip, but don't know which module is responsible for access to it?

I was trying to load ichwd module, but it is only Intel watchdog module?
