I can see that as it is clear in the diff, but this doesn't explain why,
which is what you need to do in your commit message.

Why is a property required for this? Is the absence of the 3 keypad
properties not sufficient to determine that you're in this mode?

I don't understand why interrupts is no longer required.

I think you should configure "dependencies:" such that if one of these
properties is added, then all 3 of them must be to preserve the current
requirements while the device is being used in keypad mode.
