Sebastian,

please do not take the rant below personally. You just happen to
trigger it.

I'm really tired of looking at the next incarnation of an OF/DT irq
chip driver, which reimplements stuff which I have consolidated in the
generic irq chip implementation with a lot of effort.

Just look at the various implementations in drivers/irqchip/ and find
out how similar they are. Moving code to drivers/irqchip/ does not
make an excuse for reestablishing the mess which was addressed by the
generic irq chip implementation.

Can you - and that means all of you ARM folks - please get your gear
together and add the missing features to the generic irq chip
implementation? I'm not going to accept more of that OF/DT frenzy.

Thanks,
