[PATCH v4 0/5] MFD/ASoC: Add support for Intel Bay Trail boards with WM5102 codec

[Hans de Goede]

Hi All,

Here is v4 of my series to add support for Intel Bay Trail based devices
which use a WM5102 codec for audio output/input.

This was developed and tested on a Lenovo Yoga Tablet 1051L.

The MFD and ASoC parts do not have any build-time dependencies
on each other. But the follow-up jack-detect series does have
patches depending on each-other and on this series. So IMHO it
would be best if this entire series would be merged through the
MFD tree to make merging the follow-up series easier.

Mark, if that is ok with you (and you are happy with the ASoC
changes) can you please Ack this ?

Changes in v4:
- Add a comment to the irq-flags override explaining that theoretically
  DSDTs using IRQF_TRIGGER_FALLING could be correct on boards where the
  IRQ controller does not support active low level interrupts

Changes in v3:
- Fix compilation error when CONFIG_ACPI is not set

Changes in v2:
- Split my WM5102 work into 2 series, one series adding basic support
  for Bay Trail boards with a WM5102 codec and a second series with
  the jack-detect work
- Various other minor code tweaks

[PATCH v4 1/5] mfd: arizona: Add MODULE_SOFTDEP("pre: arizona_ldo1")

[Hans de Goede]

The (shared) probing code of the arizona-i2c and arizona-spi modules
takes the following steps during init:

1. Call mfd_add_devices() for a set of early child-devices, this
includes the arizona_ldo1 device which provides one of the
core-regulators.

2. Bulk enable the core-regulators.

3. Read the device id.

4. Call mfd_add_devices() for the other child-devices.

This sequence depends on 1. leading to not only the child-device
being created, but also the driver for the child-device binding
to it and registering its regulator.

This requires the arizona_ldo1 driver to be loaded before the
shared probing code runs. Add a softdep for this to both modules to
ensure that this requirement is met.

Note this mirrors the existing MODULE_SOFTDEP("pre: wm8994_regulator")
in the wm8994 code, which has a similar init sequence.

[PATCH v4 2/5] mfd: arizona: Replace arizona_of_get_type() with device_get_match_data()

[Hans de Goede]

Replace the custom arizona_of_get_type() function with the generic
device_get_match_data() helper. Besides being a nice cleanup this
also makes it easier to add support for binding to ACPI enumerated
devices.

While at it also fix a possible NULL pointer deref of the id
argument to the probe functions (this could happen on e.g. manual
driver binding through sysfs).

[PATCH v4 3/5] mfd: arizona: Add support for ACPI enumeration of WM5102 connected over SPI

[Hans de Goede]

The Intel Bay Trail (x86/ACPI) based Lenovo Yoga Tablet 2 series use
a WM5102 codec connected over SPI.

Add support for ACPI enumeration to arizona-spi so that arizona-spi can
bind to the codec on these tablets.

This is loosely based on an earlier attempt (for Android-x86) at this by
Christian Hartmann, combined with insights in things like the speaker GPIO
from the android-x86 android port for the Lenovo Yoga Tablet 2 1051F/L [1].

[PATCH v4 4/5] ASoC: Intel: Add DMI quirk table to soc_intel_is_byt_cr()

[Hans de Goede]

Some Bay Trail systems:
1. Use a non CR version of the Bay Trail SoC
2. Contain at least 6 interrupt resources so that the
   platform_get_resource(pdev, IORESOURCE_IRQ, 5) check to workaround
   non CR systems which list their IPC IRQ at index 0 despite being
   non CR does not work
3. Despite 1. and 2. still have their IPC IRQ at index 0 rather then 5

Add a DMI quirk table to check for the few known models with this issue,
so that the right IPC IRQ index is used on these systems.

[PATCH v4 5/5] ASoC: Intel: bytcr_wm5102: Add machine driver for BYT/WM5102

[Hans de Goede]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

Add a new ASoc Machine driver for Intel Baytrail platforms with a
Wolfson Microelectronics WM5102 codec.

This is based on a past contributions [1] from Paulo Sergio Travaglia
<pstglia@gmail.com> based on the Levono kernel [2] combined with
insights in things like the speaker GPIO from the android-x86 android
port for the Lenovo Yoga Tablet 2 1051F/L [3].

[1] https://patchwork.kernel.org/project/alsa-devel/patch/593313f5.3636c80a.50e05.47e9@mx.google.com/
[2] https://github.com/lenovo-yt2-dev/android_kernel_lenovo_baytrail/blob/cm-12.1/sound/soc/intel/board/byt_bl_wm5102.c
[3] https://github.com/Kitsune2222/Android_Yoga_Tablet_2-1051F_Kernel

The original machine driver from the Android ports was a crude modified
copy of bytcr_rt5640.c adjusted to work with the WM5102 codec.
This version has been extensively reworked to:

1. Remove all rt5640 related quirk handling. to the best of my knowledge
this setup is only used on the Lenovo Yoga Tablet 2 series (8, 10 and 13
inch models) which all use the same setup. So there is no need to deal
with all the variations with which we need to deal on rt5640 boards.

2. Rework clock handling, properly turn off the FLL and the platform-clock
when they are no longer necessary and don't reconfigure the FLL
unnecessarily when it is already running. This fixes a number of:
"Timed out waiting for lock" warnings being logged.

3. Add the GPIO controlled Speaker-VDD regulator as a DAPM_SUPPLY

This only adds the machine driver and ACPI hooks, the BYT-CR detection
quirk which these devices need will be added in a separate patch.

I believe that this series and the follow-up:

"[PATCH v4 00/13] MFD/extcon/ASoC: Rework arizona codec jack-detect support"

series are both ready for merging. All patches have Reviewed-by and/or
Acked-by tags now.

I guess it is too late for 5.12, but it would be nice to at least formulate
a plan for getting this merged after 5.12-rc1 is out. Given the
interdependencies I still believe that it is best to merge all the patches
through the mfd tree and then have Lee provide an immutable branch for the
other subsystems to merge.

Mark and extcon-maintainers (for the follow-up series) may we have your ack
for merging these through the MFD tree ?

Regards,

Hans

I don't think they do.  You're missing ASoC and Extcon Acks.

Not sure why *this* set fell through the cracks though.  However, it's
now on my to-review list.

If I can work fast enough, maybe this series can get into 5.12, but
the follow-up still needs reviews.

It might be best to collect the *-bys you do have and [RESEND].

Yes, that's fine.

Right, what I meant is that the patches have been reviewed by other
stake-holders, including the follow-up series being tested by the cirrus
codec folks (thank you Charles).

But yes the actual subsys maintainers have not acked these yet;
and I'm aware that you will need those for merging this through
the MFD tree.

Note that this series only requires Mark ack, the follow-up
also touches extcon code, this one is purely MFD + ASoC patches.

The usual pattern here is that the MFD patches get merged and then I
pull a shared branch in for any dependencies - at this point the series
is now on the backlog of serieses where I'm waiting for the MFD to sort
itself out before I really look at it again.

I understand. But this series is somewhat special, if you also take
the follow-up series into account:

"[PATCH v4 resend 00/13] MFD/extcon/ASoC: Rework arizona codec jack-detect support"

That again has some MFD bits, and some extcon patches and ASoC patches
which depend on the extcon bits and this series.

So it is really hard to merge all the bits through there separate trees
and just merging it all through one tree and then pulling in the end-result
as a shared branch would IMHO be easier.

In the follow-up series one of the patches is moving the jackdet code from the
extcon dir to sound/asoc/codecs. So that is a single commit touching 2 trees ...

Hans

I tend to push patches awaiting Acks to the back of the queue.

That series is drifting along in the same way AFAICT, and it's also got
the extcon dependency so it'll need to leave it a bit longer for extcon
review (unless some happens sooner).

Most of this for me is just about not wanting to have to repeatedly look
at the same series as it goes through small changes due to changes in

We were?

This set has all the Acks we need to proceed.  What's blocking?

I'm only going to ack things if I expect to see them applied via another
tree, that's generally what an ack means from a maintainer.  Especially
with ASoC where we keep on having subsystem wide changes quite often I'm
not likely to do that for things like new drivers unless it's very clear
what the timelines are.

It would be enormously helpful to get the bits of the core MFDs that
create dependencies committed while the rest of the series is still in
process, as well as allowing things to be applied it also helps with
knowing if the dependencies are stable.

There's the subsystem maintainer...

The default point-of-view is; if a patch was submitted as part of a
set, it's likely that it makes the most sense to merge it as a set.

Very often sets will have inter-dependencies (usually headers) which
would otherwise require the base patches to be applied (perhaps the
MFD core and the headers) in one release, followed by the accompanying
child device changes during a subsequent release.  This doesn't scale
well and puts the contributor in an unfair position.

This is how we usually work together.  Why is ASoC so different?

I assume that was a question and you meant "where's"?

Pierre is listed as the Maintainer.

What is a Subsystem [0] anyway? ;)

Blocking the whole series is itself not ideal since it means the whole
large series keeps on getting resent for minor changes in individual
patches where it's only a small number of leaf patches that have issues, 
with a lot of these serieses the reason they're bundled together is that
there's some constants being added in one of the early patches that gets
used everywhere else, not that there's a really a particularly strong
relationship.

You had been sharing pull requests for the common bits in the past which
had resolved the dependency issues?

> This is how we usually work together.  Why is ASoC so different?

Like I say we've got active work that ends up doing subsystem wide
interface changes on a fairly frequent basis which then creates issues
if a new user pops up that's still trying to use the old API.  Often
it's fine but coordinating near the time is safer than just acking with
a potentially long lead time on things actually going through.

I'm fairly sure you can see what I meant here and why there might be a

So that should be a Reviewed-by and not an Acked-by then.  That's fine.

What do you want to happen with this set then?

You want it broken up?

No, it's that there's plenty of drivers like this that are listed in
MAINTAINERS but still generally go through subsystem trees - this is
also true of for quite a few MFD drivers, you tend to get a bit annoyed
(quite reasonably) whenever I mistakenly pull MFD changes for them into
one of my trees without syncing with you.

> What do you want to happen with this set then?

I guess, or at least a pull request so it's in my tree and I'll notice
any coverage issues.

Driver Maintainers in MFD don't sent Acks.

Ah, that's not the case elsewhere (and there's the case where the driver
maintainer is sending patches for their own driver which causes a bit of
confusion).

[4/5] ASoC: Intel: Add DMI quirk table to soc_intel_is_byt_cr()

[5/5] ASoC: Intel: bytcr_wm5102: Add machine driver for BYT/WM5102
      commit: 9a87fc1e061900e81ab13d823e85012a78849244

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
