Do you mean that we should change #interrupt-cells back to 3 for sysirq
and remove the 4th parameters of every spi interrupts in mt8183.dtsi
(i.e. 3 parameters for spi, 4 for ppi) such that we can discard this
patch?
If yes, we may need some time to verify the change before resending the
patch.
Thanks.
