tlv320adc3xxx: Allow MICBIAS pins to be used as
Merge series from Ricard Wanderlof <ricard.wanderlof@axis.com>:
In some cases, depending on system design, the MICBIAS pins on the
chip are not needed as such, but a couple of extra GPIO pins would be
useful. This patch allows the MICBIAS pins to be configured in the
device tree as general purpose output pins, controlled via the GPIO
framework.
Owing to their originally intended purpose there are some limitations:
when the MICBIAS pins are deactivated, they will float, so will likely
need a pulldown in many applications. When activated, they will
assume the voltage specified by the micbias1-vg and micbias2-vg
properties, respectively, meaning that the resulting output voltage
will be 2.0 V, 2.5 V or AVDD .

ASoC: cs35l56: Disconnect ASP1 TX sources when ASP1 DAI is hooked up
If the ASP1 DAI is hooked up by the machine driver the ASP TX mixer
sources should be initialized to disconnected. There aren't currently
any available products using the ASP so this doesn't affect any
existing systems.
The cs35l56 does not have any fixed default for the mixer source
registers. When the cs35l56 boots, its firmware patches these registers
to setup a system-specific routing; this is so that Windows can use
generic SDCA drivers instead of needing knowledge of chip-specific
registers. The setup varies between end-products, which each have
customized firmware, and so the default register state varies between
end-products. It can also change if the firmware on an end-product is
upgraded - for example if a change was needed to the routing for Windows
use-cases. It must be emphasized that the settings applied by the
firmware are not internal magic tuning; they are statically implementing
use-case setup that on Linux would be done via ALSA controls.
The driver is currently syncing the mixer controls with whatever
initial state the firmware wrote to the registers, so that they report
the actual audio routing. But if the ASP DAI is hooked up this can create
a powered-up DAPM graph without anything intentionally setting up a path.
This can lead to parts of the audio system powering up unexpectedly.
For example when cs35l56 is connected to cs42l43 using a codec-codec link,
this can create a complete DAPM graph which then powers-up cs42l43. But
the cs42l43 can only be clocked from its SoundWire bus so this causes a
bunch of errors in the kernel log where cs42l43 is unexpectedly powered-up
without a clock.
If the host is taking ownership of the ASP (either directly or as a
codec-to-codec link) there is no need to keep the mixer settings that the
firmware wrote. The driver has ALSA controls for setting these using
standard Linux mechanisms. So if the machine driver hooks up the ASP the
ASP mixers are initialized to "None" (no input). This prevents unintended
DAPM-graph power-ups, and means the initial state of the mixers is
always going to be None.
Since the initial state of the mixers can vary from system to system and
potentially between firmware upgrades, no use-case manager can currently
assume that cs35l56 has a known initial state. The firmware could just as
easily default them to "None" as to any input source. So defaulting them
to "None" in the driver is not increasing the entropy of the system.

ASoC: codecs: wcd937x: add wcd937x audio codec
Merge series from Mohammad Rafi Shaik <quic_mohs@quicinc.com>:
This patchset adds support for Qualcomm WCD9370/WCD9375 codec.
Qualcomm WCD9370/WCD9375 Codec is a standalone Hi-Fi audio codec IC
connected over SoundWire. This device has two SoundWire devices, RX and
TX respectively supporting 3 x ADCs, ClassH, Ear, Aux PA, 2xHPH,
6 DMICs and MBHC.
For codec driver to be functional it would need both tx and rx Soundwire devices
to be up and this is taken care by using device component framework and device-links
are used to ensure proper pm dependencies. Ex tx does not enter suspend
before rx or codec is suspended.
This patchset along with other SoundWire patches on the list
have been tested on QCM6490 IDP device.

ASoC: dt-bindings: omap-mcpdm: Convert to DT schema
Convert the OMAP4+ McPDM bindings from txt to yaml (dtschema).
Drop ti,hwmods property as it is not needed since the sysc conversion.
Add dma, dma-names, reg-names properties to match the DTS so as to not
break the already existing ABI.
Also update example node to match the existing node in the DTS.
