We need to convert all old gpio irqchips to pass the irqchip

drivers/gpio/TODO.

For chained irqchips this is a pretty straight-forward conversion.

This will conflict with our for-next.

Ah, I did cherry-pick intel-pinctrl for-next into my tree a couple of days
back, but I see there is a new "pinctrl: cherryview: Missed type change to unsigned int"
commit there which causes this conflict. I have cherry picked this new
commit into my tree and I will send out a v4 which should not conflict.

Perhaps now it makes sense to

	if (need_valid_mask) {
		chip->irq.init_valid_mask = chv_init_irq_valid_mask;
	} else {
		irq_base = devm_irq_alloc_descs(pctrl->dev, -1, 0,
		...
	} >
?

Ack good one, will also change this for v4.

Hans

p.s.

About upstreaming this, I know this has a pre-requisite on the new add_ranges
callback stuff, but how about Linus Walleij creating an immutable branch
of his tree with the first series which adds the add_ranges callback in
there and then you merge that branch into pinctrl-intel/for-next and then
we just upstream all of this for 5.5 ? That seems easier then spreading
it out over 2 cycles. Just my 2 cents.
