PATCH 2/3 arm: spear13xx: Fix dmas cells

The "dmas" cells for the designware DMA controller need to have only 3 properties apart from the phandle: request line, src master and destination master. But the commit 6e8887f60f60 updated it incorrectly while moving from platform code to DT. Fix it.

Ok. Left the tags there, but didn't merge into fixes since we're late in -rc and this didn't seem critical at this time.

My plan was to have these in the fixes branch in the hope of making it to a clean build for 4.15 after all, they fix warnings that got introduced by the updated dtc checks in 4.15-rc1.

We are getting fairly close, but it seems we still miss a few, so we might as well give up at this point. The remaining fixes should be easy to backport into v4.15.y if we decide to do it, of further back even. For v4.14 and before, the in-kernel copy of dtc won't warn, but mainline dtc will.

Greg, let me know your thoughts on this for the upcoming 4.15.y release. We had hundreds of dtc warnings in 4.15-rc1, many of them about important bugs, now we're down to a couple of warnings for platforms we don't care about much, and I expect the last of these fixes to land in 4.16-rc1 or maybe -rc2. Shall we backport them all to get a clean 4.15.y release?

Note: there was at least one dtc warning fix that caused a serious regression in code that relied on a device probe to fail because of an invalid node (a fix is still in the works for 4.15), though generally the fixes are really harmless and can only make things better.

I think it makes more sense to disable the warnings than to backport a bunch of warning fixes this late. The code is working, has worked for a long time it's just that Rob enabled the warnings by default. We can keep them enabled for 4.16.

Rob?

In some cases "working" was what's in the DT is unused by the kernel because the DT is broken. That's why this round was not off by default.

It looks to me to be somewhere less than 5 fixes remaining (BTW, why is there no arm32 allmodconfig build on kernelci.org? That or allyesconfig are the only ways to build all dtbs). It would also be an exception to the the stable process because that patch would not be in Linus' tree.

Applying them now for 4.15 would be late, but tagging them as fixes in 4.16 would not be late (other than the normal problem that things get applied to stable before sufficient testing in master).

Turning them off by default hasn't worked great either. For some, I'm not sure we can ever get to warning free, but I'd like new stuff to have warnings enabled and no one builds with W=1. We could put together tooling to just show new warnings, but someone has to run it and enforce it. I could stick dtc updates into linux-next for multiple cycles before sending to Linus.

I build them but my script that analyses for warnings only looks for the gcc "warning:" output. Need to do grep -i to catch them.

I've sent patches for all the remaining MODULE_LICENSE warnings earlier this week, and we should now have patches for almost all the dtc warnings in flight. This is what I still see on my randconfig builder with linux-next + arm-soc/for-next + patches I sent:

Not sure why the spear warnings are still there, maybe Viresh missed those or you missed one of his patches?

I hope Linus Walleij can find out what the right interrupt-parent should be on the
nomadik machine, that is otherwise the last remaining warning. Apparently the clcd driver doesn't actually need its interrupt, so we could decide to just comment
out that line if we don't know which controller it's connected to.

I am migrating it to the new DRM driver which uses the IRQ to sync screen output to avoid tearing so it would be unfortunate.

I hope Linus Walleij can find out what the right interrupt-parent should be on the
nomadik machine, that is otherwise the last remaining warning.

OK I will look into it.

I took another look myself now since this was the last remaining dtc warning in linux-next. The answer was easy enough to find in the git history for the board files: all the on-chip devices are connected to the same VIC instance. I'll send the patch.

PATCH 1/3 arm: spear600: Add missing interrupt-parent of rtc

In reply to Arnd Bergmann
Quoted 5 lines · Arnd Bergmann

I've sent patches for all the remaining MODULE_LICENSE warnings earlier this week, and we should now have patches for almost all the dtc warnings in flight. This is what I still see on my randconfig builder with linux-next + arm-soc/for-next + patches I sent:

Quoted 15 lines

arch/arm/boot/dts/spear1310-evb.dtb: Warning (gpios_property):
Missing property '#gpio-cells' in node /interrupt-controller at ec801000 or bad phandle (referred from /ahb/apb/spi at e0100000:cs-gpios[6])

arch/arm/boot/dts/spear600-evb.dtb: Warning
(interrupts_property): Missing interrupt-parent for /ahb/apb/rtc at fc900000

These are all the warnings we got earlier. So none of my patches are in the branch you tested I believe. Can you do a git log and see if they are present ?

I checked again on today's linux-next and all your patches are there, and the warning is gone. Whatever caused the warnings to still appear seems to be gone now. Sorry for the confusion.

PATCH 1/3 arm: spear600: Add missing interrupt-parent of rtc

In reply to Olof Johansson

The interrupt-parent of rtc was missing, add it.

Fixes 8113ba917dfa ("ARM: SPEAr: DT: Update device nodes")
Cc stable at vger.kernel.org # v3.8+

Applied to next/dt. Is stable really needed on this? It's been broken since pretty much forever, and nobody has complained... :)

The SPEAr architecture is widely used (in modified variants) by a large industrial automation company, 20+ years of support cycle.

However I think they have a forked both kernel and hardware, so they will not notice any time soon, and when they eventually upgrade they can simply pick the latest I guess.

Yours,
Linus Walleij

We have a customer using mainline v4.14 on their Spear600 based products.

I guess the reason why nobody complained is simply because nobody is using the SoC RTC ;)
