IDT 79RC3243x SoCs integrated a gpio controller, which handles up
to 32 gpios. All gpios could be used as interrupt source.

I would recommend looking for latest new drivers in GPIO subsystem to see
how you may improve yours.

Could give me a better pointer to it ? I looked at a lot of gpio driver
and took what fitted best.

Here just one question, why it can not be a module

that's probably doable...

quoted

why arch_initcall() is used

without that interrupts weren't avaiable early enough.

and why you put a dead code into it (see the first part of the
question)?

hmm, pointer please ?

It's already in the question above, do your homework :-)

is this some sort of joke I'm not getting ?

git log --oneline drivers/gpio/Makefile

2ad74f40dacc gpio: visconti: Add Toshiba Visconti GPIO support

that's the latest driver added in v5.12-rc8. Is that a good one ?
