I assume 10 is timeout, 5 is pre timeout, but in the driver code the default value is 30/10, I think the example dts[i] should use same default values as in code. BTW, for kdump kernel Pratyush is working on kdump on wdt enabled system. Basiclly we expect one configure longer timeout, and kick it in shorter period so we can get a chance to save vmcore. 10s sounds too short for the case..
