Ah, the numbers come from the data sheet. Please just remove the
header then, there is no need to keep them as an ABI, in particular
when the driver doesn't even include that header today.

I see you even have names for them in the node:

        charger {
-               interrupts = <TPS65217_IRQ_AC>, <TPS65217_IRQ_USB>;
+               interrupts = <TPS65217_IRQ_AC_POWER>, <TPS65217_IRQ_USB_POWER>;
                interrupts-names = "AC", "USB";
                status = "okay";

What matters here is the binding documentation in
Documentation/devicetree/bindings/power/supply/tps65217_charger.txt

Please fix that instead to mandate that the two interrupts are
required, what their functions are, and what the interrupt-names
(not interrupts-names) property must list.
