Which means my previous assertion in V1 that the IP didn't exist on stih415/6 SoC is most likely wrong, as the watchdog driver has bindings already for those platforms. I did try this before and couldn't get it working (driver failed on clk_get_rate) on stih416-b2020. Did you try and see if you can get this also working for stih415/6 SoCs? It would mean we can move away from arm_global_timer for all upstreamed STI platforms. regards, Peter. -- To unsubscribe from this list: send the line "unsubscribe linux-watchdog" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
