In this patch [1], the GPIO controller add support for describing hardware with a three-cell scheme: gpios = <&gpio instance offset flags>; It also result describing interrupts in three-cell as this in DT: node { interrupt-parent = <&gpio>; interrupts = <instance hwirq irqflag>; } This series try to extend describing interrupts with three-cell scheme. The first patch will parse interrupt irq and flag from last two cells, the second patch support finding irqdomain with interrupt instance info.
