b09a655dc7 ASoC: da7213: Populate max_register to regmap_config
commit 9d4f9f6a7b upstream.

On the Renesas RZ/G3S SMARC Carrier II board having a DA7212 codec (using
da7213 driver) connected to one SSIF-2 available on the Renesas RZ/G3S SoC
it has been discovered that using the runtime PM API for suspend/resume
(as will be proposed in the following commits) leads to the codec not
being propertly initialized after resume. This is because w/o
max_register populated to regmap_config the regcache_rbtree_sync()
breaks on base_reg > max condition and the regcache_sync_block() call is
skipped.

b5bcf578e8 ASoC: codecs: Fix atomicity violation in snd_soc_component_get_drvdata()
commit 1157733344 upstream.

An atomicity violation occurs when the validity of the variables
da7219->clk_src and da7219->mclk_rate is being assessed. Since the entire
assessment is not protected by a lock, the da7219 variable might still be
in flux during the assessment, rendering this check invalid.

To fix this issue, we recommend adding a lock before the block
if ((da7219->clk_src == clk_id) && (da7219->mclk_rate == freq)) so that
the legitimacy check for da7219->clk_src and da7219->mclk_rate is
protected by the lock, ensuring the validity of the check.

This possible bug is found by an experimental static analysis tool
developed by our team. This tool analyzes the locking APIs
to extract function pairs that can be concurrently executed, and then
analyzes the instructions in the paired functions to identify possible
concurrency bugs including data races and atomicity violations.

550279449f ASoC: mediatek: Check num_codecs is not zero to avoid panic during probe
[ Upstream commit 2f2020327c ]

Following commit 13f58267cd ("ASoC: soc.h: don't create dummy
Component via COMP_DUMMY()"), COMP_DUMMY() became an array with zero
length, and only gets populated with the dummy struct after the card is
registered. Since the sound card driver's probe happens before the card
registration, accessing any of the members of a dummy component during
probe will result in undefined behavior.

This can be observed in the mt8188 and mt8195 machine sound drivers. By
omitting a dai link subnode in the sound card's node in the Devicetree,
the default uninitialized dummy codec is used, and when its dai_name
pointer gets passed to strcmp() it results in a null pointer dereference
and a kernel panic.

In addition to that, set_card_codec_info() in the generic helpers file,
mtk-soundcard-driver.c, will populate a dai link with a dummy codec when
a dai link node is present in DT but with no codec property.

The result is that at probe time, a dummy codec can either be
uninitialized with num_codecs = 0, or be an initialized dummy codec,
with num_codecs = 1 and dai_name = "snd-soc-dummy-dai". In order to
accommodate for both situations, check that num_codecs is not zero
before accessing the codecs' fields but still check for the codec's dai
name against "snd-soc-dummy-dai" as needed.

While at it, also drop the check that dai_name is not null in the mt8192
driver, introduced in commit 4d4e1b6319 ("ASoC: mediatek: mt8192:
Check existence of dai_name before dereferencing"), as it is actually
redundant given the preceding num_codecs != 0 check.

fb09049c51 ASoC: fsl-asoc-card: Add missing handling of {hp,mic}-dt-gpios
[ Upstream commit cfd1054c65 ]

The DT bindings deprecated the "hp-det-gpio" and "mic-det-gpio"
properties in favor of "hp-det-gpios" and "mic-det-gpios", but the
driver was never updated to support the latter.

Even before, there existed users of "hp-det-gpios" and "mic-det-gpios".
While this may have been handled fine by the ASoC core, this was missed
by the Freescale-specific part.

ASoC: codecs: wcd937x: relax the AUX PDM watchdog
On a system with wcd937x, rxmacro and Qualcomm audio DSP, which is pretty
common set of devices on Qualcomm platforms, and due to the order of how
DAPM widgets are powered on (they are sorted), there is a small time window
when wcd937x chip is online and expects the flow of incoming data but
rxmacro is not yet online. When wcd937x is programmed to receive data
via AUX port then its AUX PDM watchdog is enabled in
wcd937x_codec_enable_aux_pa(). If due to some reasons the rxmacro and
soundwire machinery are delayed to start streaming data, then there is
a chance for this AUX PDM watchdog to reset the wcd937x codec. Such event
is not logged as a message and only wcd937x IRQ counter is increased
however there could be a lot of other reasons for that IRQ.
There is a similar opportunity for such delay during DAPM widgets power
down sequence.

If wcd937x codec reset happens on the start of the playback, then there
will be no sound and if such reset happens at the end of a playback then
it may generate additional clicks and pops noises.

On qrb4210 RB2 board without any debugging bits the wcd937x resets are
sometimes observed at the end of a playback though not always.
With some debugging messages or with some tracing enabled the AUX PDM
watchdog resets the wcd937x codec at the start of a playback and there
is no sound output at all.

In this patch:
 - TIMEOUT_SEL bit in PDM_WD_CTL2 register is set to increase the watchdog
reset delay to 100ms which eliminates the AUX PDM watchdog IRQs on
qrb4210 RB2 board completely and decreases the number of unwanted clicks
noises;

 - HOLD_OFF bit postpones triggering such watchdog IRQ till wcd937x codec
reset which usually happens at the end of a playback. This allows to
actually output some sound in case of debugging.

ASoC: dapm: fix bounds checker error in dapm_widget_list_create
The widgets array in the snd_soc_dapm_widget_list has a __counted_by
attribute attached to it, which points to the num_widgets variable. This
attribute is used in bounds checking, and if it is not set before the
array is filled, then the bounds sanitizer will issue a warning or a
kernel panic if CONFIG_UBSAN_TRAP is set.

This patch sets the size of the widgets list calculated with
list_for_each as the initial value for num_widgets as it is used for
allocating memory for the array. It is updated with the actual number of
added elements after the array is filled.

Qualcomm Soundwire driver to each individual machine sound card driver,
except that it forgot to update SC7280 card.

Just like for other Qualcomm sound cards using Soundwire, the card
driver should allocate and release the runtime.  Otherwise sound
playback will result in a NULL pointer dereference or other effect of
uninitialized memory accesses (which was confirmed on SDM845 having

ASoC: codecs: lpass-rx-macro: fix RXn(rx,n) macro for DSM_CTL and SEC7 regs
Turns out some registers of pre-2.5 version of rxmacro codecs are not
located at the expected offsets but 0xc further away in memory. So far
the detected registers are CDC_RX_RX2_RX_PATH_SEC7 and
CDC_RX_RX2_RX_PATH_DSM_CTL.

CDC_RX_RXn_RX_PATH_DSM_CTL(rx, n) macro incorrectly generates the address
0x540 for RX2 but it should be 0x54C and it also overwrites
CDC_RX_RX2_RX_PATH_SEC7 which is located at 0x540.
The same goes for CDC_RX_RXn_RX_PATH_SEC7(rx, n).

Fix this by introducing additional rxn_reg_stride2 offset. For 2.5 version
and above this offset will be equal to 0.
With such change the corresponding RXn() macros will generate the same
values for 2.5 codec version for all RX paths and the same old values
for pre-2.5 version for RX0 and RX1. However for the latter case with
RX2 path it will also add rxn_reg_stride2 on top.

While at this, also remove specific if-check for INTERP_AUX from
rx_macro_digital_mute() and rx_macro_enable_interp_clk(). These if-check
was used to handle such special offset for AUX interpolator but since
CDC_RX_RXn_RX_PATH_SEC7(rx, n) and CDC_RX_RXn_RX_PATH_DSM_CTL(rx, n)
macros will generate the correst addresses of dsm register, they are no
longer needed.

ASoC: rsnd: Fix probe failure on HiHope boards due to endpoint parsing
On the HiHope boards, we have a single port with a single endpoint defined
as below:
....

                rsnd_endpoint: endpoint {
                        remote-endpoint = <&dw_hdmi0_snd_in>;

                        playback = <&ssi2>;
                };
        };
....

With commit 547b02f74e ("ASoC: rsnd: enable multi Component support for
Audio Graph Card/Card2"), support for multiple ports was added. This caused
probe failures on HiHope boards, as the endpoint could not be retrieved due
to incorrect device node pointers being used.

This patch fixes the issue by updating the `rsnd_dai_of_node()` and
`rsnd_dai_probe()` functions to use the correct device node pointers based
on the port names ('port' or 'ports'). It ensures that the endpoint is
properly parsed for both single and multi-port configurations, restoring
compatibility with HiHope boards.

ASoC: max98388: Fix missing increment of variable slot_found
The variable slot_found is being initialized to zero and inside
a for-loop is being checked if it's reached MAX_NUM_CH, however,
this is currently impossible since slot_found is never changed.
In a previous loop a similar coding pattern is used and slot_found
is being incremented. It appears the increment of slot_found is
missing from the loop, so fix the code by adding in the increment.

ASoC: qcom: sdm845: add missing soundwire runtime stream alloc
During the migration of Soundwire runtime stream allocation from
the Qualcomm Soundwire controller to SoC's soundcard drivers the sdm845
soundcard was forgotten.

At this point any playback attempt or audio daemon startup, for instance
on sdm845-db845c (Qualcomm RB3 board), will result in stream pointer
NULL dereference:

    ^^^
This is 0x6108 + offset 0x44 from the beginning of sdw_stream_add_slave()
where data abort happens.
wsa881x_hw_params() is called with stream = NULL and passes it further
in register x4 (5th argument) to sdw_stream_add_slave() without any checks.
Value from x4 is copied to x25 and finally it aborts on trying to load
a value from address in x25 plus offset 32 (in dec) which corresponds
to master_list member in struct sdw_stream_runtime:

struct sdw_stream_runtime {
        const char  *              name;	/*     0     8 */
        struct sdw_stream_params   params;	/*     8    12 */
        enum sdw_stream_state      state;	/*    20     4 */
        enum sdw_stream_type       type;	/*    24     4 */
        /* XXX 4 bytes hole, try to pack */
 here-> struct list_head           master_list;	/*    32    16 */
        int                        m_rt_count;	/*    48     4 */
        /* size: 56, cachelines: 1, members: 6 */
        /* sum members: 48, holes: 1, sum holes: 4 */
        /* padding: 4 */
        /* last cacheline: 56 bytes */

Fix this by adding required calls to qcom_snd_sdw_startup() and
sdw_release_stream() to startup and shutdown routines which restores
the previous correct behaviour when ->set_stream() method is called to
set a valid stream runtime pointer on playback startup.

Reproduced and then fix was tested on db845c RB3 board.
