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.
