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

[Hans de Goede]

Hi All,

Here is v4 of my series to rework the arizona codec jack-detect support
to use the snd_soc_jack helpers instead of direct extcon reporting.

As discussed before here is a resend rebased on 5.12-rc2, making sure that
all patches this depends on are in place.

Lee, can you pick-up patches 1-6 through the MFD tree and then send a
pull-req to Mark so that Mark can merge the Asoc parts throught the ASoC
tree ?

Patches 2-6 touch drivers/extcon, these all have an Ack from Chanwoo Choi
for merging these through the MFD tree.

Here is some more generic info on this series from the previous
cover-letter:

This is done by reworking the extcon driver into an arizona-jackdet
library and then modifying the codec drivers to use that directly,
replacing the old separate extcon child-devices and extcon-driver.

This brings the arizona-codec jack-detect handling inline with how
all other ASoC codec driver do this. This was developed and tested on
a Lenovo Yoga Tablet 1051L with a WM5102 codec.

This was also tested by Charles Keepax, one of the Cirrus Codec folks.

Regards,

Hans

[PATCH v4 resend 01/13] mfd: arizona: Drop arizona-extcon cells

[Hans de Goede]

The arizona jack-dection handling is being reworked so that the
codec-child-device drivers directly handle jack-detect themselves,
so it is no longer necessary to instantiate "arizona-extcon"
child-devices.

[PATCH v4 resend 02/13] extcon: arizona: Fix some issues when HPDET IRQ fires after the jack has been unplugged

[Hans de Goede]

When the jack is partially inserted and then removed again it may be
removed while the hpdet code is running. In this case the following
may happen:

1. The "JACKDET rise" or ""JACKDET fall" IRQ triggers
2. arizona_jackdet runs and takes info->lock
3. The "HPDET" IRQ triggers
4. arizona_hpdet_irq runs, blocks on info->lock
5. arizona_jackdet calls arizona_stop_mic() and clears info->hpdet_done
6. arizona_jackdet releases info->lock
7. arizona_hpdet_irq now can continue running and:
7.1 Calls arizona_start_mic() (if a mic was detected)
7.2 sets info->hpdet_done

Step 7 is undesirable / a bug:
7.1 causes the device to stay in a high power-state (with MICVDD enabled)
7.2 causes hpdet to not run on the next jack insertion, which in turn
    causes the EXTCON_JACK_HEADPHONE state to never get set

This fixes both issues by skipping these 2 steps when arizona_hpdet_irq
runs after the jack has been unplugged.

[PATCH v4 resend 03/13] extcon: arizona: Fix various races on driver unbind

[Hans de Goede]

We must free/disable all interrupts and cancel all pending works
before doing further cleanup.

Before this commit arizona_extcon_remove() was doing several
register writes to shut things down before disabling the IRQs
and it was cancelling only 1 of the 3 different works used.

Move all the register-writes shutting things down to after
the disabling of the IRQs and add the 2 missing
cancel_delayed_work_sync() calls.

This fixes various possible races on driver unbind. One of which
would always trigger on devices using the mic-clamp feature for
jack detection. The ARIZONA_MICD_CLAMP_MODE_MASK update was
done before disabling the IRQs, causing:
1. arizona_jackdet() to run
2. detect a jack being inserted (clamp disabled means jack inserted)
3. call arizona_start_mic() which:
3.1 Enables the MICVDD regulator
3.2 takes a pm_runtime_reference

And this was all happening after the ARIZONA_MICD_ENA bit clearing,
which would undo 3.1 and 3.2 because the ARIZONA_MICD_CLAMP_MODE_MASK
update was being done after the ARIZONA_MICD_ENA bit clearing.

So this means that arizona_extcon_remove() would exit with
1. MICVDD enabled and 2. The pm_runtime_reference being unbalanced.

MICVDD still being enabled caused the following oops when the
regulator is released by the devm framework:

[ 2850.745757] ------------[ cut here ]------------
[ 2850.745827] WARNING: CPU: 2 PID: 2098 at drivers/regulator/core.c:2123 _regulator_put.part.0+0x19f/0x1b0

Note this oops is just one of various theoretically possible races caused
by the wrong ordering inside arizona_extcon_remove(), this fixes the
ordering fixing all possible races, including the reported oops.

[PATCH v4 resend 04/13] extcon: arizona: Fix flags parameter to the gpiod_get("wlf, micd-pol") call

[Hans de Goede]

The initial value of the GPIO should match the info->micd_modes[0].gpio
value. arizona_extcon_probe() already stores the necessary flag in a
mode variable, but instead of passing mode as flags to the gpiod_get()
it was using a hardcoded GPIOD_OUT_LOW.

[PATCH v4 resend 05/13] extcon: arizona: Always use pm_runtime_get_sync() when we need the device to be awake

[Hans de Goede]

Before this commit the extcon-arizona code was mixing pm_runtime_get()
and pm_runtime_get_sync() in different places.

In all places where pm_runtime_get[_sync]() is called, the code
makes use of the device immediately after the call.
This means that we should always use pm_runtime_get_sync().

[PATCH v4 resend 06/13] ASoC/extcon: arizona: Move arizona jack code to sound/soc/codecs/arizona-jack.c

[Hans de Goede]

The jack handling for arizona codecs is being refactored so that it is
done directly by the codec drivers, instead of having an extcon-driver
bind to a separate "arizona-extcon" child-device for this.

drivers/mfd/arizona-core.c has already been updated to no longer
instantiate an "arizona-extcon" child-device for the arizona codecs.

This means that the "arizona-extcon" driver is no longer useful
(there are no longer any devices for it to bind to).

This commit drops the extcon Kconfig / Makefile bits and moves
drivers/extcon/extcon-arizona.c to sound/soc/codecs/arizona-jack.c .

This is a preparation patch for converting the arizona extcon-driver into
a helper library for letting the arizona codec-drivers directly report jack
state through the standard sound/soc/soc-jack.c functions.

Move all the jack-detect variables from struct arizona_extcon_info to
struct arizona_priv.

This is part of a patch series converting the arizona extcon driver into
a helper library for letting the arizona codec-drivers directly report jack
state through the standard sound/soc/soc-jack.c functions.

[PATCH v4 resend 08/13] ASoC: arizona-jack: Use arizona->dev for runtime-pm

[Hans de Goede]

Drivers for MFD child-devices such as the arizona codec drivers
and the arizona-extcon driver can choose to either make
runtime_pm_get/_put calls on their own child-device, which will
then be propagated to their parent; or they can make them directly
on their MFD parent-device.

The arizona-extcon code was using runtime_pm_get/_put calls on
its own child-device where as the codec drivers are using
runtime_pm_get/_put calls on their parent.

The arizona-extcon MFD cell/child-device has been removed and this
commit is part of refactoring the arizona-extcon code into a library
to be used directly from the codec drivers.

Specifically this commit moves the code over to make
runtime_pm_get/_put calls on the parent device (on arizona->dev)
bringing the code inline with how the codec drivers do this.

Note this also removes the pm_runtime_enable/_disable calls
as pm_runtime support has already been enabled on the parent-device
by the arizona MFD driver.

This is part of a patch series converting the arizona extcon driver into
a helper library for letting the arizona codec-drivers directly report
jack state through the standard sound/soc/soc-jack.c functions.

[PATCH v4 resend 09/13] ASoC: arizona-jack: convert into a helper library for codec drivers

[Hans de Goede]

Convert the arizona extcon driver into a helper library for direct use
from the arizona codec-drivers, rather then being bound to a separate
MFD cell.

Note the probe (and remove) sequence is split into 2 parts:

1. The arizona_jack_codec_dev_probe() function inits a bunch of
jack-detect specific variables in struct arizona_priv and tries to get
a number of resources where getting them may fail with -EPROBE_DEFER.

2. Then once the machine driver has create a snd_sock_jack through
snd_soc_card_jack_new() it calls snd_soc_component_set_jack() on
the codec component, which will call the new arizona_jack_set_jack(),
which sets up jack-detection and requests the IRQs.

This split is necessary, because the IRQ handlers need access to the
arizona->dapm pointer and the snd_sock_jack which are not available
when the codec-driver's probe function runs.

Note this requires that machine-drivers for codecs which are converted
to use the new helper functions from arizona-jack.c are modified to
create a snd_soc_jack through snd_soc_card_jack_new() and register
this jack with the codec through snd_soc_component_set_jack().

Changes in v3:
- Pass dev (the codec-device) to devm_regulator_get instead of
  passing arizona->dev. This is necessary so that the regulator gets
  properly released when the coded driver unbinds.

[PATCH v4 resend 10/13] ASoC: arizona-jack: Use snd_soc_jack to report jack events

[Hans de Goede]

Use the snd_soc_jack code to report jack events, instead of using extcon
for reporting the cable-type + an input_dev for reporting the button
presses.

The snd_soc_jack code will report the cable-type through both input_dev
events and through ALSA controls and the button-presses through input_dev
events.

Note that this means that when the codec drivers are moved over to use
the new arizona-jack.c library code instead of having a separate MFD
extcon cell with the extcon-arizona.c driver, we will no longer report
extcon events to userspace for cable-type changes. This should not be
a problem since "standard" Linux distro userspace does not (and has
never) used the extcon class interface for this. Android does have
support for the extcon class interface, but that was introduced in
the same release as support for input_dev cable-type events, so this
should not be a problem for Android either.

Note this also reduces ARIZONA_MAX_MICD_RANGE from 8 to 6, this is
ok to do since this info is always provided through pdata (or defaults)
and cannot be overridden from devicetree. All in-kernel users of the
pdata (and the fallback defaults) define 6 or less buttons/ranges.

[PATCH v4 resend 11/13] ASoC: arizona-jack: Cleanup logging

[Hans de Goede]

Cleanup the use of dev_foo functions used for logging:

1. Many of these are unnecessarily split over multiple lines
2. Use dev_err_probe() in cases where we might get a -EPROBE_DEFER
   return value

Changes in v4:
- While at it also change (on adjescent lines) "if (ret != 0)" into "if (ret)"
- Do not unnecessary split one of the dev_err_probe() calls over multiple lines

Changes in v3:
- This is a new patch in v3 of this patch-series

[PATCH v4 resend 12/13] ASoC: arizona: Make the wm5102, wm5110, wm8997 and wm8998 drivers use the new jack library

[Hans de Goede]

Make all arizona codec drivers for which drivers/mfd/arizona-core.c used
to instantiate a "arizona-extcon" child-device use the new arizona-jack.c
library for jack-detection.

This has been tested on a Lenovo Yoga Tablet 2 1051L with a WM5102 codec.

[PATCH v4 resend 13/13] ASoC: Intel: bytcr_wm5102: Add jack detect support

[Hans de Goede]

Add jack detect support by creating a jack and calling
snd_soc_component_set_jack to register the created jack
with the codec.

Lee, is there a specific reason why these have not been merged yet,
or did you just not get around to these yet ?

As I already mentioned Chanwoo Choi already gave an ack for merging
the extcon patches through MFD, so AFAICT eveything is ready to merge
1-6 through the MFD tree, and then have Mark merge an ib from the
MFD tree and merge the rest.

Regards,

Hans

I can't remember where we left it.

I guess I can take 1-6 (as suggested above) without issue.

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

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

[Hans de Goede]

Hi all,

Here is v4 of my series to rework the arizona codec jack-detect support
to use the snd_soc_jack helpers instead of direct extcon reporting.

This is a resend with some extra *-by tags collected and with the extcon
folks added to the "To:" list, which I somehow missed with the original
v4 posting, sorry.

This is done by reworking the extcon driver into an arizona-jackdet
library and then modifying the codec drivers to use that directly,
replacing the old separate extcon child-devices and extcon-driver.

This brings the arizona-codec jack-detect handling inline with how
all other ASoC codec driver do this. This was developed and tested on
a Lenovo Yoga Tablet 1051L with a WM5102 codec.

This was also tested by Charles Keepax, one of the Cirrus Codec folks.

This depends on the previously posted "[PATCH v4 0/5] MFD/ASoC: Add
support for Intel Bay Trail boards with WM5102 codec" series and there
are various interdependencies between the patches in this series.

Lee Jones, the MFD maintainer has agreed to take this series upstream
through the MFD tree and to provide an immutable branch for the ASoC
and extcon subsystems to merge.

Mark and extcon-maintainers may we have your ack for merging these
through the MFD tree ?

Regards,

Hans

[PATCH v4 resend 07/13] ASoC: arizona-jack: Move jack-detect variables to struct arizona_priv

[Hans de Goede]

Move all the jack-detect variables from struct arizona_extcon_info to
struct arizona_priv.

This is part of a patch series converting the arizona extcon driver into
a helper library for letting the arizona codec-drivers directly report jack
state through the standard sound/soc/soc-jack.c functions.
