ASoC: spacemit: adjust FIFO trigger threshold to half FIFO size

2026-04-29T02:41:32+00:00

Set both TX and RX FIFO trigger thresholds (TFT/RFT) to 0xF (half of
the 32-entry FIFO) instead of 5. This provides better DMA efficiency
by allowing more data to accumulate before triggering a DMA request,
reducing the number of DMA transactions needed.

ASoC: spacemit: move hw constraints from hw_params to startup

2026-04-29T02:41:32+00:00

Hardware constraints should be applied in the startup callback rather
than hw_params, as hw_params may be called too late for the constraints
to take effect properly.

Move the channel count and format constraints for I2S and DSP_A/DSP_B
modes into a new startup callback. This also tightens the I2S mode
channel constraint from 1-2 to exactly 2, matching the actual hardware
behavior.

ASoC: codecs: ab8500: Fix casting of private data

2026-04-29T00:47:39+00:00

ab8500_filter_controls[i].private_value is initialized using

	.private_value = (unsigned long)&(struct filter_control)
		{.count = xcount, .min = xmin, .max = xmax}

thus it's a pointer to a struct filter_control casted to unsigned long.

So to get back that pointer .private_data must be cast back, not its
address.

ASoC: cs35l56: Fix illegal writes to OTP_MEM registers

2026-04-28T23:41:14+00:00

Mark the OTP_MEM registers as volatile so that regcache_sync() will not
attempt to write to them.

These registers hold a constant, and originally they were marked as
readable non-volatile so that this value would be read into the regmap
cache. The problem with this is regcache_sync() issues a write for any
cached register that does not have a reg_default.

Though these registers are constants and writing them in normal use
cannot change OTP, it is illegal for the host to write to them.

ASoC: Intel: bytcr_wm5102: Fix MCLK leak on platform_clock_control error

2026-04-28T08:50:08+00:00

If byt_wm5102_prepare_and_enable_pll1() fails in the
SND_SOC_DAPM_EVENT_ON() path, platform_clock_control() returns after
clk_prepare_enable(priv->mclk) without disabling the clock again.

This leaks an MCLK enable reference on failed power-up attempts. Add the
missing clk_disable_unprepare() on the error path, matching the unwind
used by the other Intel platform_clock_control() implementations.

ASoC: aw88395: Fix kernel panic caused by invalid GPIO error pointer

2026-04-28T03:40:32+00:00

In aw88395_i2c_probe(), if `devm_gpiod_get_optional()` fails, it returns
an ERR_PTR() error pointer. The current code only prints a message and
continues execution, leaving `aw88395->reset_gpio` as an invalid pointer.

Later, in `aw88395_hw_reset()`, this invalid pointer is passed to
`gpiod_set_value_cansleep()`, which dereferences it and causes a kernel
panic.

For optional GPIOs, `devm_gpiod_get_optional()` returns NULL if the GPIO
is not defined in the DT, which is safe. If it returns an ERR_PTR, it
means a real error occurred (e.g., -EPROBE_DEFER) and the probe must be
aborted.

Also, since the GPIO is optional, remove the dev_err() log in
aw88395_hw_reset() when the GPIO is missing to match the optional
semantics. This also fixes a potential NULL pointer dereference as
aw_pa is not initialized when aw88395_hw_reset() is called.

ASoC: ES8389: convert to devm_clk_get_optional() to get clock

2026-04-26T23:30:22+00:00

When enabling ES8390 via ACPI description, es8389 would fail to
obtain a clock source, causing the driver to fail to initialize.
This was not an issue with older kernels, but since commit
abae8e57e49a ("clk: generalize devm_clk_get() a bit"),
devm_clk_get() would return an error pointer when a clock source
was not detected (instead of falling back to a static clock),
causing the driver to fail early.

Use devm_clk_get_optional() instead to return to the previous
behaviour, allowing the use of a static clock source.

ASoC: tegra: Remove stale snd-soc-tegra-utils composite module definition

2026-04-26T23:23:21+00:00

kconfiglint reports two warnings for sound/soc/tegra/Makefile:

  M002: composite module 'snd-soc-tegra-utils' defined but not in any obj-*
  M008: composite module 'snd-soc-tegra-utils': tegra_asoc_utils.o has no
        source file

The composite module definition
`snd-soc-tegra-utils-y += tegra_asoc_utils.o` references a source file that
no longer exists and defines a module that is never included in any obj-*
target.

The tegra_asoc_utils module was originally introduced in commit
a3cd50deef7b ("ASoC: Tegra: Move utilities to separate module") by Stephen
Warren in 2011 to provide shared clock/rate utility functions for Tegra
machine drivers. At that time, the Makefile had both the composite
definition (`snd-soc-tegra-utils-objs`) and the build target
(`obj-$(CONFIG_SND_TEGRA_SOC) += snd-soc-tegra-utils.o`).

In 2021,
commit 8c1b3b159300 ("ASoC: tegra: Squash utils into common machine
driver")
by Dmitry Osipenko merged tegra_asoc_utils.c into tegra_asoc_machine.c,
deleting both the .c and .h files. That commit correctly removed the obj-*
build target line but overlooked the composite module definition line
(`snd-soc-tegra-utils-objs += tegra_asoc_utils.o`).

The orphaned line persisted unnoticed and was even mechanically updated in
2024 by
commit 51a50d6ad727 ("ASoC: tegra: Use *-y instead of *-objs in
Makefile")
by Takashi Iwai, which converted it from `-objs` to `-y` syntax as part of
a treewide cleanup — inadvertently refreshing a stale definition.

Remove the orphaned composite module definition since it serves no purpose:
the source file was deleted, the obj-* target was already removed, and the
functionality now lives in tegra_asoc_machine.c.

ASoC: tas2770: Fix order of operations for temperature calculation

2026-04-26T21:58:07+00:00

The order of operations to derive the temperature from the temp
register values was wrong, since 1000 / 16 is not an integer. This
resulted in the calculated temperature value deviating from the
value represented by the registers slightly, which was most obvious
when the registers were zeroed (-92.265 *C vs the expected -93.000 *C).

Scale the reading before dividing the whole thing by 16 to correct
this.
