6d2d2aaae1 ASoC: da7219-aad: fix usage of device_get_named_child_node()
[ Upstream commit e8a6a5ad73acbafd98e8fd3f0cbf6e379771bb76 ]

The documentation for device_get_named_child_node() mentions this
important point:

"
The caller is responsible for calling fwnode_handle_put() on the
returned fwnode pointer.
"

Add fwnode_handle_put() to avoid a leaked reference.

5c50d2e998 ASoC: rt5645: Fix the electric noise due to the CBJ contacts floating
[ Upstream commit 103abab975087e1f01b76fcb54c91dbb65dbc249 ]

The codec leaves tie combo jack's sleeve/ring2 to floating status
default. It would cause electric noise while connecting the active
speaker jack during boot or shutdown.
This patch requests a gpio to control the additional jack circuit
to tie the contacts to the ground or floating.

a6f9bd4aee ASoC: ops: Fix wraparound for mask in snd_soc_get_volsw
[ Upstream commit fc563aa900659a850e2ada4af26b9d7a3de6c591 ]

In snd_soc_info_volsw(), mask is generated by figuring out the index of
the most significant bit set in max and converting the index to a
bitmask through bit shift 1. Unintended wraparound occurs when max is an
integer value with msb bit set. Since the bit shift value 1 is treated
as an integer type, the left shift operation will wraparound and set
mask to 0 instead of all 1's. In order to fix this, we type cast 1 as
`1ULL` to prevent the wraparound.

e7221531b9 ASoC: meson: axg-tdm-interface: fix mclk setup without mclk-fs
[ Upstream commit e3741a8d28a1137f8b19ae6f3d6e3be69a454a0a ]

By default, when mclk-fs is not provided, the tdm-interface driver
requests an MCLK that is 4x the bit clock, SCLK.

However there is no justification for this:

* If the codec needs MCLK for its operation, mclk-fs is expected to be set
  according to the codec requirements.
* If the codec does not need MCLK the minimum is 2 * SCLK, because this is
  minimum the divider between SCLK and MCLK can do.

Multiplying by 4 may cause problems because the PLL limit may be reached
sooner than it should, so use 2x instead.

53b5234209 ASoC: rt5645: Make LattePanda board DMI match more precise
[ Upstream commit 551539a8606e28cb2a130f8ef3e9834235b456c4 ]

The DMI strings used for the LattePanda board DMI quirks are very generic.

Using the dmidecode database from https://linux-hardware.org/ shows
that the chosen DMI strings also match the following 2 laptops
which also have a rt5645 codec:

Insignia NS-P11W7100 https://linux-hardware.org/?computer=E092FFF8BA04
Insignia NS-P10W8100 https://linux-hardware.org/?computer=AFB6C0BF7934

All 4 hw revisions of the LattePanda board have "S70CR" in their BIOS
version DMI strings:

DF-BI-7-S70CR100-*
DF-BI-7-S70CR110-*
DF-BI-7-S70CR200-*
LP-BS-7-S70CR700-*

See e.g. https://linux-hardware.org/?computer=D98250A817C0

Add a partial (non exact) DMI match on this string to make the LattePanda
board DMI match more precise to avoid false-positive matches.

them.

Drop the includes.

Further the driver is requesting "reset-gpios" rather than
just "reset" from the GPIO framework. This is wrong because
the gpiolib core will add "-gpios" before processing the
request from e.g. device tree. Drop the suffix.

The last problem means that the optional RESET GPIO has
never been properly retrieved and used even if it existed,
but nobody noticed.

[ Upstream commit 41bae58df411f9accf01ea660730649b2fab1dab ]

asoc_simple_probe() is used for both "DT probe" (A) and "platform probe"
(B). It uses "goto err" when error case, but it is not needed for
"platform probe" case (B). Thus it is using "return" directly there.

	static int asoc_simple_probe(...)
	{
 ^		if (...) {
 |			...
(A)			if (ret < 0)
 |				goto err;
 v		} else {
 ^			...
 |			if (ret < 0)
(B)				return -Exxx;
 v		}

		...
 ^		if (ret < 0)
(C)			goto err;
 v		...

	err:
(D)		simple_util_clean_reference(card);

		return ret;
	}

Both case are using (C) part, and it calls (D) when err case.
But (D) will do nothing for (B) case.
Because of these behavior, current code itself is not wrong,
but is confusable, and more, static analyzing tool will warning on
(B) part (should use goto err).

To avoid static analyzing tool warning, this patch uses "goto err"
on (B) part.

When handling an AAD interrupt, if IRQ events read failed (for example,
due to i2c "Transfer while suspended" failure, i.e. when attempting to
read it while DA7219 is suspended, which may happen due to a spurious
AAD interrupt), the events array contains garbage uninitialized values.
So instead of trying to interprete those values and doing any actions
based on them (potentially resulting in misbehavior, e.g. reporting
bogus events), refuse to handle the interrupt.

[ Upstream commit 91e292917dad64ab8d1d5ca2ab3069ad9dac6f72 ]

da7219_aad_suspend() disables jack detection, which should prevent
generating new interrupts by DA7219 while suspended. However, there is a
theoretical possibility that there is a pending interrupt generated just
before suspending DA7219 and not handled yet, so the IRQ handler may
still run after DA7219 is suspended. To prevent that, wait until the
pending IRQ handling is done.

This patch arose as an attempt to fix the following I2C failure
occurring sometimes during system suspend or resume:

[  355.876211] i2c_designware i2c_designware.3: Transfer while suspended
[  355.876245] WARNING: CPU: 2 PID: 3576 at drivers/i2c/busses/i2c-designware-master.c:570 i2c_dw_xfer+0x411/0x440

which indicates that the AAD IRQ handler is unexpectedly running when
DA7219 is suspended, and as a result, is trying to read data from DA7219
over I2C and is hitting the I2C driver "Transfer while suspended"
failure.

However, with this patch the above failure is still reproducible. So
this patch does not fix any real observed issue so far, but at least is
useful for confirming that the above issue is not caused by a pending
IRQ but rather looks like a DA7219 hardware issue with an IRQ
unexpectedly generated after jack detection is already disabled.

67d8b2cecb ASoC: meson: axg-tdm-formatter: fix channel slot allocation
[ Upstream commit c1f848f12103920ca165758aedb1c10904e193e1 ]

When the tdm lane mask is computed, the driver currently fills the 1st lane
before moving on to the next. If the stream has less channels than the
lanes can accommodate, slots will be disabled on the last lanes.

Unfortunately, the HW distribute channels in a different way. It distribute
channels in pair on each lanes before moving on the next slots.

This difference leads to problems if a device has an interface with more
than 1 lane and with more than 2 slots per lane.

For example: a playback interface with 2 lanes and 4 slots each (total 8
slots - zero based numbering)
- Playing a 8ch stream:
  - All slots activated by the driver
  - channel #2 will be played on lane #1 - slot #0 following HW placement
- Playing a 4ch stream:
  - Lane #1 disabled by the driver
  - channel #2 will be played on lane #0 - slot #2

This behaviour is obviously not desirable.

Change the way slots are activated on the TDM lanes to follow what the HW
does and make sure each channel always get mapped to the same slot/lane.

e292a6124d ASoC: cs42l51: fix driver to properly autoload with automatic module loading
commit e51df4f81b02bcdd828a04de7c1eb6a92988b61e upstream.

In commit 2cb1e0259f50 ("ASoC: cs42l51: re-hook of_match_table
pointer"), 9 years ago, some random guy fixed the cs42l51 after it was
split into a core part and an I2C part to properly match based on a
Device Tree compatible string.

However, the fix in this commit is wrong: the MODULE_DEVICE_TABLE(of,
....) is in the core part of the driver, not the I2C part. Therefore,
automatic module loading based on module.alias, based on matching with
the DT compatible string, loads the core part of the driver, but not
the I2C part. And threfore, the i2c_driver is not registered, and the
codec is not known to the system, nor matched with a DT node with the
corresponding compatible string.

In order to fix that, we move the MODULE_DEVICE_TABLE(of, ...) into
the I2C part of the driver. The cs42l51_of_match[] array is also moved
as well, as it is not possible to have this definition in one file,
and the MODULE_DEVICE_TABLE(of, ...) invocation in another file, due
to how MODULE_DEVICE_TABLE works.

Thanks to this commit, the I2C part of the driver now properly
autoloads, and thanks to its dependency on the core part, the core
part gets autoloaded as well, resulting in a functional sound card
without having to manually load kernel modules.

c599ce16ab ASoC: es8316: Increment max value for ALC Capture Target Volume control
[ Upstream commit 6f073429037cd79d7311cd8236311c53f5ea8f01 ]

The following error occurs when trying to restore a previously saved
ALSA mixer state (tested on a Rock 5B board):

  $ alsactl --no-ucm -f /tmp/asound.state store hw:Analog
  $ alsactl --no-ucm -I -f /tmp/asound.state restore hw:Analog
  alsactl: set_control:1475: Cannot write control '2:0:0:ALC Capture Target Volume:0' : Invalid argument

According to ES8316 datasheet, the register at address 0x2B, which is
related to the above mixer control, contains by default the value 0xB0.
Considering the corresponding ALC target bits (ALCLVL) are 7:4, the
control is initialized with 11, which is one step above the maximum
value allowed by the driver:

 ALCLVL | dB gain
 -------+--------
  0000  |  -16.5
  0001  |  -15.0
  0010  |  -13.5
  ....  |  .....
  0111  |   -6.0
  1000  |   -4.5
  1001  |   -3.0
  1010  |   -1.5
  ....  |  .....
  1111  |   -1.5

The tests performed using the VU meter feature (--vumeter=TYPE) of
arecord/aplay confirm the specs are correct and there is no measured
gain if the 1011-1111 range would have been mapped to 0 dB:

 dB gain | VU meter %
 --------+-----------
   -6.0  |  30-31
   -4.5  |  35-36
   -3.0  |  42-43
   -1.5  |  50-51
    0.0  |  50-51

Increment the max value allowed for ALC Capture Target Volume control,
so that it matches the hardware default.  Additionally, update the
related TLV to prevent an artificial extension of the dB gain range.

b7de5a3297 ASoC: ssm2602: Add workaround for playback distortions
[ Upstream commit f63550e2b165208a2f382afcaf5551df9569e1d4 ]

Apply a workaround for what appears to be a hardware quirk.

The problem seems to happen when enabling "whole chip power" (bit D7
register R6) for the very first time after the chip receives power. If
either "output" (D4) or "DAC" (D3) aren't powered on at that time,
playback becomes very distorted later on.

This happens on the Google Chameleon v3, as well as on a ZYBO Z7-10:
https://ez.analog.com/audio/f/q-a/543726/solved-ssm2603-right-output-offset-issue/480229
I suspect this happens only when using an external MCLK signal (which
is the case for both of these boards).

Here are some experiments run on a Google Chameleon v3. These were run
in userspace using a wrapper around the i2cset utility:
ssmset() {
        i2cset -y 0 0x1a $(($1*2)) $2
}

For each of the following sequences, we apply power to the ssm2603
chip, set the configuration registers R0-R5 and R7-R8, run the selected
sequence, and check for distortions on playback.

  ssmset 0x09 0x01 # core
  ssmset 0x06 0x07 # chip, out, dac
  OK

  ssmset 0x09 0x01 # core
  ssmset 0x06 0x87 # out, dac
  ssmset 0x06 0x07 # chip

  (disable MCLK)
  ssmset 0x09 0x01 # core
  ssmset 0x06 0x1f # chip
  ssmset 0x06 0x07 # out, dac
  (enable MCLK)
  OK

  ssmset 0x09 0x01 # core
  ssmset 0x06 0x1f # chip
  ssmset 0x06 0x07 # out, dac

  ssmset 0x06 0x1f # chip
  ssmset 0x09 0x01 # core
  ssmset 0x06 0x07 # out, dac

  ssmset 0x09 0x01 # core
  ssmset 0x06 0x0f # chip, out

  ssmset 0x09 0x01 # core
  ssmset 0x06 0x17 # chip, dac
  ssmset 0x06 0x07 # out
  NOT OK

For each of the following sequences, we apply power to the ssm2603
chip, run the selected sequence, issue a reset with R15, configure
R0-R5 and R7-R8, run one of the NOT OK sequences from above, and check
for distortions.

While looking through legacy platform data users, I noticed that
the DT probing never uses data from the DT properties, as the
platform_data structure gets overwritten directly after it
is initialized.

There have never been any boards defining the platform_data in
the mainline kernel either, so this driver so far only worked
with patched kernels or with the default values.

For the benefit of possible downstream users, fix the DT probe
by no longer overwriting the data.

[ Upstream commit 6d94d0090527b1763872275a7ccd44df7219b31e ]

rk_spdif_runtime_resume() may have called clk_prepare_enable() before return
from failed branches, add missing clk_disable_unprepare() in this case.

The node returned by of_parse_phandle() with refcount incremented,
of_node_put() needs be called when finish using it. So add it in the

[ Upstream commit 97b801be6f8e53676b9f2b105f54e35c745c1b22 ]

The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context. We fix it by going to
err_pm instead of err_clk.

e40408bab0 ASoC: ops: Correct bounds check for second channel on SX controls
commit f33bcc506050f89433a52a3052054d4ebd37b1c1 upstream.

Currently the check against the max value for the control is being
applied after the value has had the minimum applied and been masked. But
the max value simply indicates the number of volume levels on an SX
control, and as such should just be applied on the raw value.
