[1/6] arm64: dts: qcom: sc8280xp-x13s: disable soundcard

  Driver support for the X13s soundcard is not yet in place so disable it
for now to avoid probe failures such as:

[   11.077727] qcom-prm gprsvc:service:2:2: DSP returned error[100100f] 1
[   11.077926] rx_macro: probe of 3200000.rxmacro failed with error -22
[   21.221104] platform 3210000.soundwire-controller: deferred probe pending

That's a double disable.

Yes, that's on purpose. We're temporarily disabling these nodes instead
of reverting the series which should not have been merged.

Once we have driver support, these properties will be updated again.

I don't get why disabling something twice is anyhow related to
"temporarily disable". One disable is enough for temporary or permanent
disables.

Linux kernel is not the only consumer of DTS, thus having or not having
the support in the kernel is not reason to disable pieces of it.
Assuming the DTS is correct, of course, because maybe that's the problem?

It clearly shows that this was done on purpose and indicates which
properties need to be changed to "okay" once we have actual support.

Okay, let's revert these sound dts changes then until we have support.
We have no idea if the dts changes are correct as sound still depends
on out-of-tree hacks.

People are using -next for development and I don't want to see them
toast their speakers because we failed get the dependencies merged
before merging the dts changes which is how we normally do this.

So shall I just send a revert instead? I really don't care as long as
this is disabled again today.

No, it shows nothing clearly as from time to time we got duplicated
properties and it's a simply mistake. The double disable without any
comment looks like mistake, not intentional code.

If the error is in DTS, yeah, revert or disable is a way. But if the
issue is in the incomplete or broken Linux drivers, then these should be
changed, e.g. intentionally fail probing, skip new devices, drop new
compatible etc.

It's not a mistake. It's intentional. And I don't want to spend hours on
this because of someone else's cock-up.

And how long does it take for that to propagate and isn't the response
just going go to be "well then fix the driver".

I think you're just being unreasonable here.

If Bjorn could rebase his tree, he could simply drop these for now as
sound support was clearly not ready. Since that isn't the case we need
to at least try to be constructive and figure out a reasonable
alternative. While "Linux isn't the only consumer" is a true statement,
it really is not relevant just because there are some dts changes in
Bjorn's tree which should not be there.

To you it looks intentional, but for the reader of DTS which has
disabled node in DTSI and in DTS - so in two places - it looks like a
pure bug. Just because you know the reason behind the change does not
make the code readable.

I did not propose to fix the driver. I proposed to fail the driver's
probe or remove the compatible from it.

Such change propagate the same speed as DTS change.

The SC8280XP audio DTS looks in general correct, except some style
issues, redundant properties and never tested against DT bindings.
Therefore it looks as accurate and more-or-less correct representation
of the hardware, unless you have some more details on this.

Is the driver is to blame, focus there, not on DTS.

Calling a (temporary) redundant property a 'pure bug' seems like a bit
of stretch, and it has nothing to do with readability.

But the DTS changes are in Bjorn branch and Bjorn and I discussed it and
decided to disable them temporarily instead of reverting.

Now you're asking me to figure out all the dependent driver and patch
them individually. And this may not reach next before the DTS changes
do.

Only that the drivers fail to probe in multiple ways, some which may
require updating the bindings to address. There's also an indication
that some further driver support is needed for proper speaker
protection. That really should be in place before we enable this.

Redundant properties is not a code which we want to have anywhere. Why
you are so opposed to documenting this oddity?

Users do not work on linux-next. linux-next is integration tree for
developers. Pretty often broken and not stable, so anyone using it
accepts the risks. Using now linux-next argument for a change is not
appropriate. The change should be reasonable regardless of users of
linux-next.

I don't think there is anything needed to fix in bindings in
incompatible way. I was working on them as well (for HDK8450) and I
don't recall any issues.

If you see anything specific, use specific arguments, because otherwise
it is just FUD.

There is easy solution for this - drop the compatible from drivers. Or
if driver is SC8280xp specific, mark it as BROKEN in Kconfig. Or fail
the probe so it won't bother your system.

I'm not at all opposed to adding a comment that this is a temporary
disable. Hopefully we can even get the driver support ready, things
tested, and enable these nodes before 6.3 is released.

The argument is that this should never have been merged last week. And
we do have users running linux-next as support for x13s is very much
still under development. Sure, they don't expect things to always work
perfectly, but I still want to avoid toasting there speakers if I can.

You can call it FUD if you want, I just call it being cautious.

Or we just revert or disable it temporarily in the x13s dts until we
better understand the missing driver bits.
