[PATCH 00/30] ARM: pxa: remove all unused boards&drivers
From: Arnd Bergmann arnd@arndb.de
Most of the legacy PXA board files were marked as unused in linux-5.19 and can get removed in linux-6.2. There is support for pxa250/pxa270/pxa300 using devicetree already, which supports a number of boards, but progress on converting the remaining ones has stalled over the past few years.
The two boards that are left in the tree for now are the three 'sharpsl' variants (spitz/akita/borzoi) and the 'gumstix' family of machines. Both of these are supported by qemu, which can be helpful for completing the DT conversion.
Only PXA25x and PXA27x are left with full boardfile support, so PXA300 can get a lot simpler while still working with DT, and PXA310/320/93x can be removed entirely.
A good number of drivers become impossible to select after this, so each of these also get dropped. I'm including the driver patches in the series here and can either merge them through the soc tree, or they can get picked up by the individual subsystem maintainers. Since both the platform and the drivers get removed, the order should not matter.
Note that the patches here are generated with 'git format-patch -D' and don't contain the contents of removed files because of the significant size (the first patch is close to a megabyte).

A good number of drivers become impossible to select after this, so each of these also get dropped. I'm including the driver patches in the series here and can either merge them through the soc tree, or they can get picked up by the individual subsystem maintainers. Since both the platform and the drivers get removed, the order should not matter.
This part is a bit ... bothering. I at least identified these :
delete mode 100644 drivers/input/touchscreen/wm9705.c delete mode 100644 drivers/input/touchscreen/wm9712.c delete mode 100644 drivers/input/touchscreen/wm9713.c delete mode 100644 drivers/input/touchscreen/wm97xx-core.c delete mode 100644 drivers/mfd/wm97xx-core.c delete mode 100644 sound/ac97/bus.c delete mode 100644 sound/ac97/codec.c delete mode 100644 sound/ac97/snd_ac97_compat.c
For the existing platforms working with devicetree support (mioa701 for example), the wm9713 was properly used, providing both sound support and input touchscreen. So was the a97 part, providing a framework to make the wm9713 work.
So I'm wondering how the choice to chop these drivers was done, and it is necessary to remove them. If so, maybe pxa support in the kernel should be removed all together, as people playing with it loose part of the working DT platforms they had.
As for the removal of defconfigs and arch-pxa, sure, this was PXA's destiny.
Cheers.

If the files are used for DT based machines, then they should definitely stay, the intention of my series was to only remove known dead code.
What I did was to remove CONFIG_UNUSED_BOARD_FILES and then recursively trim out all code that could be compiled in before but not after this change, assuming that this would be safe.
What I see here is that AC97_BUS_NEW and SND_PXA2XX_SOC_AC97 are selected by eight legacy board files (tosa, e740, e750, e800, em_x270, palm27x, zylonite and mioa701), but no DT based machine, so without CONFIG_UNUSED_BOARD_FILES, the entire AC97_BUS_NEW infrastructure and all drivers depending on this became dead code.
Unfortunately I ran into problems sending out the rest of the series after sending the cover letter, so the explanations I put in the individual patches were not here. See [1] for the actual series.
Since it looks like I'll have to redo half of the PXA patches after leaving AC97_BUS_NEW in, I won't post the full version first.
Any idea where I went wrong here? Did I make a mistake in following the Kconfig dependencies, or are some parts of this incorrectly annotated?

This answer will most probably look horrible, probably in html with no way of using plain text... sorry for that.
The reason you're not seeing the AC97_BUS_NEW used is because this becomes visible only in device-tree files, which were posted (for mioa701 for example) but never properly reviewed nor merged.
As from memory, at least mioa701, zylonite, em_x270 are DT ported, ie. there is a DT file which makes them boot. For the mioa701, the DT file offers the same functionnality, ie. all drivers in mioa701.c legacy file are working as well in a DT variant (not using mioa701.c obviously).
Any idea where I went wrong here? Did I make a mistake in following
the Kconfig dependencies, or are some parts of this incorrectly annotated?
I don't think you did a mistake, I think I did. When I saw the patch of "deprecation" of mioa701 and all the other pxa files, I took it that the platform-device was deprecated, and was to be removed. This is the right thing to do in my opinion. I wouldn't mind if all board file go actually (expect the QEMU one), as this would leave only the boards with proper DT support, and would remove some clutter from the kernel.
I also thought the drivers won't get touched by the purge, exception made of "platform similar ones", such as in the sound tree (sound/soc/pxa) where we have some of them, and maybe mfd tree.
Cheers.

Ok, I see. I need a little clarification here, so I can adapt my patch series to keep the necessary files in place:
- Zylonite has both PXA300 and PXA320 variants. I removed the PXA320 code because nothing selected it any more and it is not hooked up to the MACH_PXA3XX_DT Kconfig symbol. Should I undo this and keep all three PXA3xx variant, removing only PXA930 but selecting CPU_PXA310/320 from MACH_PXA3XX_DT?
- The em_x270 board file was already removed as part of 9d3239147d6d ("ARM: pxa: remove Compulab pxa2xx boards"), which already removed the associated drivers. Is it correct to assume that the DT support for it has also become unusable at that point, or would you expect it to still have some use? I now remove the related CM-X300 machine as well, but it sounds like you did not have DT support for that, right?
- I'm not sure how the probing of the ASoC drivers works in the DT case. Do I only need to make SND_PXA2XX_SOC_AC97 user-visible to let everything get probed automatically from DT, or do we need to also keep SND_PXA2XX_SOC_MIOA701 and SND_SOC_ZYLONITE?

This is the right thing to do in my opinion. I wouldn't mind if all board file go actually (expect the QEMU one), as this would leave only the boards with proper DT support, and would remove some clutter from the kernel.
Right, this is the plan: the only board files I left in place are 'gumstix' family that is supported by qemu and has the largest amount of RAM in there, and the 'spitz' family that is also supported by qemu and apparently had at least one user that was interested in working on DT (I can't find a record of who that was now).
I also thought the drivers won't get touched by the purge, exception made of "platform similar ones", such as in the sound tree (sound/soc/pxa) where we have some of them, and maybe mfd tree.
I made two lists of drivers here: the first list is for those that become invisible in Kconfig and can no longer even be compile tested. My reasoning here was that these are likely already dead and will only get worse without compile testing. If anyone ends up doing a new DT conversion of a removed board later on, these can obviously get resurrected. The current state of the patches is in [1], I'll go through them again based on your feedback, but let me know if you see anything else that I'm removing that you think should be kept.
The second list of drivers is for those that have no DT support and are impossible to get used without anyone declaring a (platform, spi, i2c, ...) device in source code somewhere. The list is still incomplete because this is hard to check automatically. I have included a few patches to remove drivers that have been obviously unused for a long time, or never had an in-tree user at all, but I left the majority of these drivers for a later series.

Most of the legacy PXA board files were marked as unused in linux-5.19 and can get removed in linux-6.2. There is support for pxa250/pxa270/pxa300 using devicetree already, which supports a number of boards, but progress on converting the remaining ones has stalled over the past few years.
The two boards that are left in the tree for now are the three 'sharpsl' variants (spitz/akita/borzoi) and the 'gumstix' family of machines. Both of these are supported by qemu, which can be helpful for completing the DT conversion.
Only PXA25x and PXA27x are left with full boardfile support, so PXA300 can get a lot simpler while still working with DT, and PXA310/320/93x can be removed entirely.
A good number of drivers become impossible to select after this, so each of these also get dropped. I'm including the driver patches in the series here and can either merge them through the soc tree, or they can get picked up by the individual subsystem maintainers. Since both the platform and the drivers get removed, the order should not matter.
Note that the patches here are generated with 'git format-patch -D' and don't contain the contents of removed files because of the significant size (the first patch is close to a megabyte).

You are right, I was interrupted after sending out the cover letter and didn't manage to finish sending the rest.
Since Robert Jarzmik already found a problem with the series overall, I'll continue sending the other (mmp, sa1100, s3c, omap2) patch sets for now and get back to PXA after we've worked out the issue with the ac97 infrastructure.
