Hi Mark, Rob
These adds R-Car D3 support for rsnd driver.
[1/3] is tidyup patch for dt-bindings (not only for D3).
[2/3], [3/3] are for R-Car D3.
Kuninori Morimoto (3):
ASoC: dt-bindings: renesas: rsnd: tidyup properties
ASoC: rsnd: tidyup loop on rsnd_adg_clk_query()
ASoC: rsnd: add null CLOCKIN support

2.25.1
NXP's TFA98xx (now part of Goodix) are fairly popular speaker amplifiers
used in many smartphones and tablets. Most of them are sold as "smart
amplifiers" with built-in "CoolFlux DSP" that is used for volume control,
plus a "sophisticated speaker-boost and protection algorithm".
Unfortunately, they are also almost entirely undocumented. The short
datasheets (e.g. [1] for TFA9897) describe the available features,
but do not provide any information about the registers or how to use
the "CoolFlux DSP".
The amplifiers are most often configured through proprietary userspace
libraries. There are also some (rather complex) kernel drivers (e.g. [2])
but even those rely on obscure firmware blobs for configuration (so-called
"containers"). They seem to contain different "profiles" with tuned speaker
settings, sample rates and volume steps (which would be better exposed
as separate ALSA mixers).
The format of the firmware files seems to have changed a lot over the time,
so it's not even possible to simply re-use the firmware originally provided
by the vendor.
Overall, it seems close to impossible to develop a proper mainline driver
for these amplifiers that could make proper use of the built-in DSP.
This commit implements a compromise: At least the TFA1 family of the
TFA98xx amplifiers (usually called TFA989x) provide a way to *bypass*
the DSP using a special register sequence. The register sequence can be
found in similar variations in the kernel drivers from lots of vendors
e.g. in [3] and was probably mainly used for factory testing.
With the DSP bypassed, the amplifier acts mostly like a dumb standard
speaker amplifier, without (hardware) volume control. However, the setup
is much simpler and it works without any obscure firmware.
This driver implements the DSP bypass combined with chip-specific
initialization sequences adapted from [2]. Only TFA9895 is supported in
this initial commit. Except for the lack of volume control I can not hear
any difference with or without the DSP, it works just fine.
This driver allows the speaker to work on mainline Linux running on the
Samsung Galaxy A3/A5 (2015) [TFA9895] and Alcatel Idol 3 [TFA9897].
TFA9897 support will be added in separate patch set later.

NXP/Goodix TFA989X (TFA1) amplifiers are controlled via an I2C bus.
Add simple device tree bindings that describe how to set them up
in the device tree.
Right now only nxp,tfa9895 is supported but this will be extended
to at least nxp,tfa9897 in the near future.

This patchset adds Amlogic SM1 support on the TOACODEC driver, first by switching
to regmap fields for some bit fields to avoid code duplication, and then by adding
the corresponding bits & struct for the SM1 changed bits.
Changes since v2 at [2]:
- use raw values instead of defines in REG_FIELD() for g12a_toacodec_match_data
Changes since v1 at [1]:
- switch to regmap field

Current dapm widget has a single variable to describe its kcontrol's
type. As there can be many kcontrols in one widget it is inherently
presumed that the types are the same.
Lately there has been use cases where different types of kcontrols would
be needed for a single widget. Thus add pointer to dapm widget to hold
an array for different kcontrol types and modify the kcontrol creation
to operate in a loop based on individual kcontrol type.
Change control creation and deletion to use individual kcontrol types in
SOF driver. This is done in the same patch for not breaking bisect. SOF
driver is also currently the only one using the dapm widget
kcontrol_type.

HSBIAS_SENSE_EN configures HSBIAS output current sense through
the external 2.21-k resistor. HSBIAS_SENSE is hardware feature to reduce
the potential pop noise during the headset plug out slowly. But on some
platforms ESD voltage will affect it causing test to fail, especially
with CTIA headset type. For different hardware setups, a designer might
want to tweak default behavior.

This reverts commit 5f1b95d08d.
The warnings that commit 5f1b95d08d ("ASoC: q6dsp: q6afe: remove
unneeded dead-store initialization") was trying to fix were already
fixed in commit 12900bacb4 ("ASoC: qcom: q6afe: remove useless
assignments"). With both commits in the tree, port_id is uninitialized,
as pointed out by clang:
sound/soc/qcom/qdsp6/q6afe.c:1213:18: warning: variable 'port_id' is
uninitialized when used here [-Wuninitialized]
stop->port_id = port_id;
^~~~~~~
sound/soc/qcom/qdsp6/q6afe.c:1186:13: note: initialize the variable
'port_id' to silence this warning
int port_id;
^
= 0
1 warning generated.
Bring back the initialization so that everything works as intended.

With more warnings than the default, Sparse throws the following
warning:
sound/soc/sof/intel/hda.c:1127:49: error: self-comparison always
evaluates to true
sound/soc/sof/intel/hda.c:1128:49: error: self-comparison always
evaluates to true
sound/soc/sof/intel/hda.c:1129:48: error: self-comparison always
evaluates to true
This looks like an obvious error, with a likely copy-pasted line
leading to the use of the wrong index in an inner loop. One of the
worst single-character bugs in a long time.
This problem was not detected in our tests since in practice SoundWire
platforms only have identical devices per link and the index mistake
did not change the results.

Hi Mark, Guillaume
I'm so sorry to bother you again and again.
These are v2 of simple-card / audio-graph re-cleanup.
KernelCI had reported that below patches broke kontron-sl28-var3-ads2
sound card probing.
434392271a "ASoC: simple-card: add simple_link_init()"
59c35c44a9 "ASoC: simple-card: add simple_parse_node()"
Main issue I'm understanding is name create timing.
We want to create dailink->name via dlc->dai_name.
But in CPU case, this dai_name might be removed by asoc_simple_canonicalize_cpu()
if it CPU was single DAI.
Thus, we need to
A) get dlc->dai_name
B) create dailink->name via dlc->dai_name
C) call asoc_simple_canonicalize_cpu()
Above reverted patch did A->C->B.
My previous v1 patch did B->A->C.
I'm so sorry that I didn't deep test on v1.
I hope v2 patches has no issues on kontron-sl28-var3-ads2.
