Subject: [PATCH 01/14] mfd: arizona: Add jack pointer to struct arizona
The Linux Arizona driver uses the MFD framework to create several
sub-devices for the Arizona codec and then uses a driver per function.
The jack-detect support for the Arizona codec is handled by the
extcon-arizona driver. This driver exports info about the jack state
to userspace through the standard extcon sysfs class interface.
But standard Linux userspace does not monitor/use the extcon sysfs
interface for jack-detection.
Add a jack pointer to the shared arizona data struct, this allows
the ASoC machine driver to create a snd_soc_jack and then pass this
to the extcon-arizona driver to report jack-detect state, so that
jack-detection works with standard Linux userspace.
The extcon-arizona code already depends on (waits for with -EPROBE_DEFER)
the snd_card being registered by the machine driver, so this does not
cause any ordering issues.

Subject: [PATCH 02/14] mfd: arizona: Add MODULE_SOFTDEP("pre: arizona_ldo1")
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 doftdep 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.

Subject: [PATCH 03/14] mfd: arizona: Add support for ACPI enumeration of
WM5102 connected over SPI
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].

Subject: [PATCH 04/14] mfd: arizona: Allow building arizona MFD-core as module
There is no reason why the arizona core,irq and codec model specific
regmap bits cannot be build as a module. All they do is export symbols
which are used by the arizona-spi and/or arizona-i2c modules, which
themselves can be built as module.
Change the Kconfig and Makefile arizona bits so that the arizona MFD-core
can be built as a module.
This is especially useful on x86 platforms with a WM5102 codec, this
allows the arizona MFD driver necessary for the WM5102 codec to be
enabled in generic distro-kernels without growing the base kernel-image
size.

Subject: [PATCH 05/14] extcon: arizona: Fix some issues when HPDET IRQ fires
after the jack has been unplugged
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 undeseriable / 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.

Subject: [PATCH 06/14] extcon: arizona: Fix various races on driver unbind
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:

Subject: [PATCH 07/14] extcon: arizona: Fix modalias
Fix the modalias so that the driver will be loaded automatically. The
module's name is "extcon-arizona", following other extcon module-names.
But the driver's and platform-device's name is "arizona-extcon" and the
modalias must match that.

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.

Subject: [PATCH 10/14] extcon: arizona: Also report jack state through
snd_soc_jack_report()
The Linux Arizona driver uses the MFD framework to create several
sub-devices for the Arizona codec and then uses a driver per function.
The extcon-arizona driver handles jack-detect support and exports info
about the jack state to userspace through the standard extcon sysfs
class interface.
Standard Linux userspace does not monitor/use the extcon sysfs interface
for jack-detection, resulting in the jack-state not being taken into
account by userspace.
The ASoC machine-driver may have created a standard ASoC jack when
registering the card. In this case also report the jack-state through the
ASoC jack so that jack-detection works with standard Linux userspace.

Subject: [PATCH 11/14] extcon: arizona: Use ASoC jack input-device when
available
When the machine driver creates an ASoC jack for jack-detect and
CONFIG_SND_JACK_INPUT_DEV is enabled then this will also create an
input-device. In this case use the already created input-device
to report button presses instead of creating a second "Headset"
input-device for the same headset.
This relies on the machine-driver setting up the jack-input-device to
report the EV_KEY key-codes configured in arizona_pdata.micd_ranges,
before registering it.

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.

Subject: [PATCH 13/14] ASoC: Intel: bytcr_wm5102: Add machine driver for
BYT/WM5102
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.

Subject: [PATCH 14/14] ASoC: Intel: bytcr_wm5102: Add jack detect support
The Linux Arizona/WM5102 driver uses the MFD framework to create several
sub-devices for the WM5102 codec and then uses a driver per function.
The jack-detect support for the WM5102 codec is handled by the
extcon-arizona driver. This driver exports info about the jack state
to userspace through the standard extcon sysfs class interface.
But standard Linux userspace does not monitor/use the extcon sysfs
interface for jack-detection.
The extcon-arizona driver can also report jack-detect state through
the standard ASoC jack interface. For this we need to create a
snd_soc_jack and pass this to the extcon-arizona driver through the
shared arizona data struct.
The extcon-arizona code already depends on (waits for with -EPROBE_DEFER)
the snd_card being registered by the machine driver, so this does not
cause any ordering issues.
