[PATCH 00/17] Device trees for Apple M2 (t8112) based devices

[PATCH 00/17] Device trees for Apple M2 (t8112) based devices

[Janne Grunau]

This series contains dt-bindings updates and device trees for Apple
silicon devices based on the M2 SoC (t8112).

Device tree validation depends ont the dart-t8110 bindings queued in
the iommu tree for 6.3 [1] and support for "local-mac-address" for
brcm,bcm4329-fmac based devices [2]. The latter fixes validation errors
for the existing M1 and M1 Pro/Max/Ultra device trees.

The device trees are tested with the downstream Asahi Linux kernel and
on top of v6.2-rc5. The hardware is of limited use with the upstream
kernel. The notebooks miss keyboard/trackpad drivers and usb support.
The Mac mini does not yet have a boot framebuffer and lacks usb support
as well.

The PMU (performance monitor) driver needs a small update which I'll
send out separately. All other driver changes are already queued. The
dt-bindings changes should be merged through asahi-soc to ensure
devicetree validation.

[PATCH 01/17] dt-bindings: power: apple,pmgr-pwrstate: Add t8112 compatible

[Janne Grunau]

From: Hector Martin <marcan@marcan.st>

Add the apple,t8112-pmgr-pwrstate compatible for the Apple M2 SoC.

This goes after t8103. The sort order logic here is having SoC numeric
code families in release order, and SoCs within each family in release
order:

- t8xxx (Apple HxxP/G series, "phone"/"tablet" chips)
  - t8103 (Apple H13G/M1)
  - t8112 (Apple H14G/M2)
- t6xxx (Apple HxxJ series, "desktop" chips)
  - t6000 (Apple H13J(S)/M1 Pro)
  - t6001 (Apple H13J(C)/M1 Max)
  - t6002 (Apple H13J(D)/M1 Ultra)

Note that t600[0-2] share the t6000 compatible where the hardware is
100% compatible, which is usually the case in this highly related set
of SoCs.

This trivial dt-bindings update should be merged through the asahi-soc
tree to ensure validation of the Apple M2 (t8112) devicetrees in this
series.

A SoB is not an r-b. I do not upstream patches that are unreviewed. I
wrote the patch. Someone needs to review it.

The extra SoB is redundant because this is going back into my tree, I
wrote it, and I will be the committer when I apply it. It's a one-liner
patch. I know what I wrote. Sure we could record Janne's SoB as a
technicality, but it feels silly. What matters more is that the patch
gets reviewed, not that on a patch series technicality it ended up being
Janne who sent it to the list. I could just pull the patch from my own
branch and then it didn't go through Janne so it doesn't need his SoB.
But it does need someone's review (because I absolutely refuse to merge
my own patches without review, although not every maintainer has that
policy unfortunately, which means there's lots of unreviewed code in the
kernel).

Please. Let's cut down on the silliness. Please. We're trying to get
stuff done here. I'm tired of having to explain every little thing over
and over and over again. I really am.

Listen, I have no clue whether Janne changed the patch or not. She might
have rebased it or not. The chain expects that anyone touching the patch
must leave SoB. I am not providing my reviewes for patches breaking the
process we have clearly described. I also do not see any problem in
following the process we have - adding SoB whenever you play with a
patch and send it. Entire discussion is silly indeed, instead of just
following the process.

I do, which is why I asked for an r-b and not an SoB.

The patch is identical to what is in my asahi tree already.

And clearly it wasn't touched here.

Good thing we don't need your review for simple compatible additions then!

Or you could just stop nitpicking and doubling down on things that don't
even concern you, since it is *my* tree and *my* job to worry about the
signoffs being kosher, not yours, as *I* am upstream in the submission
path and you are not.

No, the bindings go via subsystem. Just because you want to validate
something is not really a reason - you can validate on next. Don't
create special rules for Asahi... or rather - why Asahi is special than
everyone else?

We did that 2 or 3 times in the past without commnts that it is not 
desired so I wasn't aware that this would be special handling.

Merging binding and devicetree updates together looks to me like the 
most sensible option since dtbs validation is the only testable 
dependecy of dt binding updates.
Keeping them together ensures the dtbs validate without delaying 
devicetree changes by one kernel release after the dt-bindings change 
was merged.
I suppose it works out most of the time if the merge request is sent 
only if it validates in next. That still depends on the merge order in 
the merge window but -rc1 should be fine.

I'll consider devicetree validation as eventually valid from now on and 
not care too much about it.

But it is not the recommended practice. Bindings were always going with
drivers and this was said by Rob multiple times.

For sure if there is no driver update at all or subsystem maintainer is
not responsive, bindings were picked up by SoC folks, but it's rather
fallback, not the main path.

dtbs will validate on next and in next release the same way if bindings
go via subsystem. I don't see the benefit nor any difference for
validation. What type of delay? Why would you ever need it?

There is no requirement of dtbs_check for bisectability. Bindings are
separate (also exported to other users), thus it is expected to have
here async.

Everything will validate once reaches next as well...

Rob also said that we can do trivial compatible additions ourselves and
don't have to involve him or subsystem maintainers. It's too trivial to
count as a "binding" change.

Let's not make this harder than it is. We have a pile of compatibles to
add every SoC that will only keep growing, and we have the situation
where this is largely a formality because it turns out the hardware *is*
compatible anyway (we just change the top compatible just in case). The
list of subsystems we touch will only keep growing. None of those
subsystem maintainers have any useful input to add to this, as the only
people with the information about what compatibles go together or don't
is us (since we're reverse engineering the hardware). All the relevant
bindings are listed in our section of MAINTAINERS. This stuff isn't
worth gratuitous added complexity and involvement. It's hard enough
getting driver changes into the kernel, let's not make it hard to get
devices that *don't* need driver changes on top of that.

>> I'll consider devicetree validation as eventually valid from now on and

> 
> Everything will validate once reaches next as well...

Only once both changes hit next. If the DT change hits next first, it
won't validate. If the DT change hits mainline first, it won't validate.
AIUI from what Rob decently told me, this is okay, so we can submit
proper bindings changes to drivers from now on. But I still maintain
that *trivial compatible additions* should go through SoC because
there's no point in involving 15 subsystems instead of 1 every time
Apple releases a new SoC that's compatible with previous ones on 14
subsystems.

BTW, your approach causes also bisectability with checkpatch on the
drivers or the delay of drivers... Therefore not much solved here.

'#interrupt-cells' to 3 for apple,t8112-aic. This is seamlessly handled
inside the driver.

"apple,t8112-sart" as found on the Apple M2 SoC appears to be SART3 as
well. To allow for later discovered incompatibilities use
'"apple,t8112-sart", "apple,t6000-sart"' as compatible string.

This trivial dt-bindings update should be merged through the asahi-soc

"apple,t8112-nvme-ans2" as found on Apple M2 SoCs is compatible with the

Given that we're at -rc8 it seems like it would be more sensible
to just merge this now so it's in -rc1, it doesn't seem likely
that everything will get sorted prior to the merge window?

I didn't get a response to my query about the nearness to the
merge window and the prospects of the series hitting v6.3, though
I do see that there's a new version needed for some of the other
patches.  I'm just going to go ahead and apply so it's there and
I don't need to worry about or see resends, in case the rest of
the series is going to go in it's not the end of the world if it
gets applied twice anyway so

Sorry, I forgot to answer. The devicetree commit is too late for 6.3. If 
some of the binding updates make it into v6.3-rc1 it will get dropped.

Aren't you now repeating exactly what is in the schema? Keep only one...

yes but I think the duplication is OK. I consider the description for 
human consumption and the schema for computer consumption. The comments 
in the schema are aids to for editing the schema. This follows the 
existing pattern for M1 and M1 Pro/Max/Ultra based devices in this file.

You should not delete devices just because they are unused. Externally
visible buses should be just disabled in DTSI and you enable them when
needed. Not the opposite way.

What's more, you must node delete nodes just because they are "not
used". This not anymore proper description of hardware.

I agree, this is copied from the M1 and M1 Pro/Max/Ultra devictrees.  
I'll fix it there as well.

I suppose because the syscon device is not limited to power domain 
controls. The dt-bindings in arm/apple/apple,pmgr.yaml specify those 
compatibles. See the original discussion in:

https://lore.kernel.org/linux-devicetree/57991dac-196e-a76d-831a-d4ac166bfe29@marcan.st/

This did not answer my concerns. There are no children here.

Ahhh, so this is overridden? Then it's fine.

[14/17] dt-bindings: sound: apple,mca: Add t8112-mca compatible
        commit: b361d5d2464a88184f6e17a6462719ba79180b1a

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
