From: Arnd Bergmann <[email protected]>
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).

This part is a bit ... bothering.

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?

Are you sure these went out?

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.

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?

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 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.
