ASoC: jack: allow multiple interrupt per gpio
This feature is required for coupled hp-mic quirk used
by some Nvidia Tegra 3 based devices work properly.

ASoC: soc-card: Create jack kcontrol without pins
snd_soc_card_jack_new() allowed to create jack kcontrol without pins,
but did not create kcontrols. The jack would not have kcontrols if pins
were not going to be added.

This renames the old snd_soc_card_jack_new() to
snd_soc_card_jack_new_pins() for use when pins are provided or will be
added later. The new snd_soc_card_jack_new() appropriately creates a
jack for use without pins and adds a kcontrol.

Lars-Peter Clausen 970939964c ASoC: Allow to register jacks at the card level
Jacks are typically card level elements, but are currently registered with a
CODEC. When it was originally introduced snd_soc_jack_new() took a
snd_soc_card as its parameter, but at that time DAPM was only implemented at
the CODEC level and there was only one CODEC per card. This made it clear
which CODEC to use for the jack DAPM operations. But the multi-component
patchset added support for having multiple CODECs per card and with it the
API was updated to register jacks with a specific CODEC instance instead.
Subsequently DAPM support at the card level has been introduced, but the
snd_soc_jack_new() API has so remained unchanged.

This leaves us with the issue that the DAPM pins that are managed by the
jack detection logic usually are part of the card DAPM context but are
accessed through a CODEC DAPM context. Currently this works fine, but might
break in the future if we take a more hierarchical approach to DAPM
contexts.

Furthermore with componentization progressing systems that do not register
a snd_soc_codec might appear, while these system may still want to able to
register a jack.

This patch addresses these issues by adding a new function called
snd_soc_card_jack_new() that can be used to register jacks with the card
rather than a CODEC.

This new function is mostly identical to snd_soc_jack_new() except that it
additionally allows to directly specify the DAPM pins associated with the
jack. This was done since most users of snd_soc_jack_new() typically call
snd_soc_jack_add_pins() right after it, which is not necessary with the new
API and allows to reduce the amount of boiler plate code.

The old snd_soc_jack_new() is re-implemented as a wrapper around
snd_soc_card_jack_new().

Both the snd_soc_codec and snd_soc_platform struct do have a pointer to the

moves the card field to the component level which will allow further code
consolidation between platforms and CODECS.

Since there are only a handful of users of the snd_soc_codec struct's card field
(and none of the snd_soc_platform's) these are update in this patch as well,
which allows it to be removed from the snd_soc_codec struct.

Jarkko Nikula f025d3b9c6 ASoC: jack: Add support for GPIO descriptor defined jack pins
Allow jack GPIO pins be defined also using GPIO descriptor-based interface
in addition to legacy GPIO numbers. This is done by adding two new fields to
struct snd_soc_jack_gpio: idx and gpiod_dev.

Legacy GPIO numbers are used only when GPIO consumer device gpiod_dev is
NULL and otherwise idx is the descriptor index within the GPIO consumer
device.

New function snd_soc_jack_add_gpiods() is added for typical cases where all
GPIO descriptor jack pins belong to same GPIO consumer device. For other
cases the caller must set the gpiod_dev in struct snd_soc_jack_gpio before
calling snd_soc_jack_add_gpios().

Currently operations on jack reporting take the CODEC mutex both to protect
the current jack status and also to protect the DAPM run which is triggered
on status updates. Since the addition of a DAPM-specific lock we no longer
need to worry about locking DAPM as it has its own finer grained lock so
create a per jack lock to take care of the jack status.

This is both cleaner where the jack isn't specifically associated with a
CODEC and clearer as it's much more obvious what the lock is protecting.

Stephen Warren 363618f013 ASoC: Name jack GPIOs based on jack not codec
snd_soc_jack_gpio has a name field. Use that name when registering the IRQ,
since this is far more informative than the codec driver name. This shows
up in /proc/interrupts.

Thomas Gleixner 458f7f8f81 sound: Fixup the last user of the old irq functions
I had seen that before, but now that I removed set_irq_wake it broke.

Mark Brown 1d2c27f941 ASoC: Pass the jack to jack notifiers
We're currently not passing anything and this will make the card and so on
more discoverable.

Mark Brown 7887ab3a27 ASoC: Allow GPIO jack detection to be configured as a wake source
Some systems wish to use jacks as wake sources. Provide a wake flag in the
GPIO configuration which causes the driver to enable the IRQ as a wake
source.

Jarkko Nikula 535787b6ae ASoC: Allow use sleeping gpio in soc-jack
It is safe to use sleeping gpio in snd_soc_jack_gpio_detect as it is not
called from interrupt context. This avoids WARN_ON from __gpio_get_value
if sleeping gpio is registered for jack.
