I think a binding should be self describing, and not rely on an opaque macro. Mentioning that there is a macro that encodes it is fine, but the values are what matter, specially when considering that other OSs could (and should be able to) write their own DTs from scratch without depending on something that is very much Linux-specific. Thanks, M.

The macros are not Linux-specific, and are part of the bindings. But the only hard dependency on <dt-bindings/interrupt-controller/irqc-rzg2l.h> is the DT source file describing the board.

The two other patches from this series were applied in v6.1. Note that the current DT bindings are incorrect, as they do not take into account that the value of zero is used to represent the NMI. Fixes: 96fed779d3d4cb3c ("dt-bindings: interrupt-controller: Add Renesas RZ/G2L Interrupt Controller") Should we resend instead? Thanks! Gr{oetje,eeting}s, Geert
