[PATCH] drivers/pcmcia: NO_IRQ removal for electra_cf.c

From: Michael Ellerman <mpe@ellerman.id.au>
Date: 2016-09-10 10:01:39 

We'd like to eventually remove NO_IRQ on powerpc, so remove usages of it
from electra_cf.c which is a powerpc-only driver.

Ping anyone?

Or should I merge this via the powerpc tree?

That's what I would recommend for a powerpc specific pcmcia driver, yes.

Looking at the bigger picture of powerpc drivers using NO_IRQ, I also

No. I stayed away from anything FSL related as I was under the
impression some of them were being ported to arch/arm, which uses -1 for
NO_IRQ IIUIC.

eg. all of include/soc/fsl and drivers/soc/fsl was moved from
arch/powerpc in commit 7aa1aa6ecec2, which said:

    QE: Move QE from arch/powerpc to drivers/soc
    
    ls1 has qe and ls1 has arm cpu.
    move qe from arch/powerpc to drivers/soc/fsl
    to adapt to powerpc and arm

But looking at the Kconfigs it looks like they're still only selectable
on PPC. So that's a bit annoying.

I'll do patches for everything above that's not drivers/soc or
include/soc and hopefully we can hear from someone at NXP on the plans
for getting the soc parts enabled on arm.

cheers

I think the removal of the NO_IRQ references is a requirement for
getting the drivers working properly on ARM, as the OF platform
code will use '0' for invalid IRQs.

OK. So the #define NO_IRQ (-1) in arch/arm/include/asm/irq.h is a red
herring and should be ignored for anything modern?

Correct. There are a couple of older (non-DT) platforms that still rely on it,
and I also have patches for those, which I intend to revisit at some point.

    move qe from arch/powerpc to drivers/soc/fsl
    to adapt to powerpc and arm

But looking at the Kconfigs it looks like they're still only selectable
on PPC. So that's a bit annoying.

I'll do patches for everything above that's not drivers/soc or
include/soc and hopefully we can hear from someone at NXP on the plans
for getting the soc parts enabled on arm.

We'd like to eventually remove NO_IRQ on powerpc, so remove usages of it
from electra_cf.c which is a powerpc-only driver.

Applied to powerpc next.
