[PATCH v2 0/7] Asoc: Various Intel rt5651 patches

[PATCH v2 0/7] Asoc: Various Intel rt5651 patches

[Hans de Goede]

Hi All,

Here is a v2 of my previous set with various Intel rt5651 patches.

This version contains a small fix to:
[PATCH v2 6/7] ASoC: Intel: bytcr_rt5651: Add support for jack-detect

I forgot to pass the gpio to snd_soc_component_set_jack from the resume
handler too (instead of only from the init function).

Other then that there are no changes, so I've kept Pierre-Louis'
Acked-by for the entire series.

Regards,

Hans

[PATCH v2 1/7] ASoC: Intel: common: Add quirk for PoV P1006W tablet

[Hans de Goede]

The Point of View TAB-P1006W-232 (v1.0) tablet uses 10EC5640 as
ACPI HID, but it has a rt5651 codec add a quirk for this.

[PATCH v2 2/7] ASoC: rt5651: Add ACPI ID 10EC5640

[Hans de Goede]

Some BYT platforms have a RT5651 codec while using an ACPI node with
a HID of 10EC5640 to describe the coded. Add the 10EC5640 HID to the
acpi_device_id list, so that the rt5651 will bind to the codec on these
devices.

Like the rt5645 and rt5670 drivers which also have the 10EC5640 ACPI HID
in their acpi_device_id list for similar reasons, the rt5651 driver checks
the codecs device-id register so that it will only bind if the codec
actually is a rt5651 and it will ignore actual rt5640 codecs.

[PATCH v2 3/7] ASoC: rt5651: Add support for jack detect using an external GPIO

[Hans de Goede]

Some board designs hook the jack-detect up to an external GPIO,
rather then to one of the codec pins, add support for this.

Figuring out which GPIO to use is pretty much board specific so I've
chosen to let the machine driver pass the gpio_desc as data argument to
snd_soc_component_set_jack() rather then add support for getting the
GPIO to the codec driver. This keeps the codec code nice and clean.

Note that using an external GPIO for this conflicts with button-press
support, so this commit disables button-press support when an
external GPIO is used.

[PATCH v2 4/7] ASoC: Intel: bytcr_rt5651: Revert "Fix DMIC map headsetmic mapping"

[Hans de Goede]

Commit 37c7401e8c1f ("ASoC: Intel: bytcr_rt5651: Fix DMIC map
headsetmic mapping"), changed the headsetmic mapping from IN3P to IN2P,
this was based on the observation that all bytcr_rt5651 devices I have
access to (7 devices) where all using IN3P for the headsetmic. This was
an attempt to unifify / simplify the mapping, but it was wrong.

None of those devices was actually using a digital internal mic. Now I've
access to a Point of View TAB-P1006W-232 (v1.0) tabler, which does use a
DMIC and it does have its headsetmic connected to IN2P, showing that the
original mapping was correct, so this commit reverts the change changing
the mapping back to IN2P.

[PATCH v2 7/7] ASoC: Intel: bytcr_rt5651: Add quirk for PoV TAB-P1006W-232 (v1.0) tablet

[Hans de Goede]

Add a DMI quirk for the Point of View TAB-P1006W-232 (v1.0) tablet, this
tablet is special in a number of ways:

1) It uses the 2nd GPIO resource in the ACPI tables for jack-detect rather
then using the rt5651 codec's builtin jack-detect functionality

2) It uses the 3th GPIO resource in the ACPI tables to control the
external amplifier rather then the usual first non GpioInt resource and
the GPIO is active-low.

3) It is a BYTCR device, without a CHAN package and it uses SSP0-AIF1
rather then the default SSP0-AIF2.

4) Its internal mic is a digital mic (the first x86 rt5651 device that
I'm aware of which does this), combined with having its headset-mic
connected to IN2.

Applied "ASoC: Intel: bytcr_rt5651: Add support for jack-detect using an external GPIO" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: bytcr_rt5651: Add support for jack-detect using an external GPIO

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

Subject: [PATCH] ASoC: Intel: bytcr_rt5651: Add support for jack-detect using
 an external GPIO

Some board designs hook the jack-detect up to an external GPIO, rather
then to one of the codec pins, add support for this.
