Ok. Did you mean separate compatible statements with data sections pointing at 
the same structure?

Like this:
{ .compatible = "dlg,da9062-watchdog", .data = &da9062_watchdog_info },
{ .compatible = "dlg,da9061-watchdog", .data = &da9062_watchdog_info },

So this would be the only change needed in the device driver.
