If I understood him correctly you either need to stick with "host-wakeup-gpios" (and fix your platform) or deprecate it in favour of "interrupts": https://lkml.kernel.org/r/20191218203818.GA8009@bogus Johan

Not sure. Perhaps just updating the binding is enough. Rob? Johan

Perhaps just updating the binding is enough. Rob? Correct. Just need to reflect in the binding which way is preferred. If it's a case of update all the dts files, then we often just don't document the old way. Rob

add interrupts and interrupt-names as optional properties to support host-wakeup by interrupt properties instead of host-wakeup-gpios.
