ASoC: codecs: ES8389: Modify the initial configuration

This commit modifies the initial configuration for the ES8389 codec.
It changes the values written to the ES8389_ISO_CTL and ES8389_OSC_CLK
registers during the initialization sequence.

[Severity: High]
This isn't a bug introduced by this patch, but I noticed that regmap_read()
is called without checking the return value. If the I2C read fails, the
stack variable reg remains uninitialized.

Does this code unintentionally use an uninitialized value for es8389->version
and in other functions like es8389_pcm_hw_params() or es8389_mute()?

For example, in es8389_resume():

sound/soc/codecs/es8389.c:es8389_resume() {
...
	regmap_read(es8389->regmap, ES8389_RESET, &regv);
	if (regv == 0xff)
...
}

If the read fails, regv could be uninitialized stack garbage, potentially
causing it to take the 0xff branch incorrectly.

[Severity: High]
This isn't a bug introduced by this patch, but looking at the component
remove callback, is it possible that we are leaking the clock and regulator
resources?

In es8389_probe(), the clock and regulators are enabled:

sound/soc/codecs/es8389.c:es8389_probe() {
...
	ret = clk_prepare_enable(es8389->mclk);
...
	ret = regulator_bulk_enable(ARRAY_SIZE(es8389_core_supplies),
				    es8389->core_supply);
...
}

However, es8389_remove() does not seem to call clk_disable_unprepare() or
regulator_bulk_disable(). Could this permanently leak these resources every
time the sound card is bound and unbound?


[Severity: High]
This is a pre-existing issue, but does the power sequencing in es8389_probe()
follow standard hardware requirements?

sound/soc/codecs/es8389.c:es8389_probe() {
...
	ret = clk_prepare_enable(es8389->mclk);
...
	ret = regulator_bulk_enable(ARRAY_SIZE(es8389_core_supplies),
				    es8389->core_supply);
...
}

The clock is enabled before the core power supplies are enabled. Can driving a
clock signal into an unpowered IC draw power through the clock pin's ESD
protection diodes, potentially causing unpredictable logic states?


[Severity: High]
This is another pre-existing issue, but could we bypass the master clock
enablement during resume?

sound/soc/codecs/es8389.c:es8389_resume() {
...
	regmap_read(es8389->regmap, ES8389_RESET, &regv);
	if (regv == 0xff)
		es8389_init(component);
	else
		es8389_set_bias_level(component, SND_SOC_BIAS_ON);
...
}

During es8389_suspend(), the bias level drops to STANDBY, disabling the
master clock. In es8389_resume(), if the register read returns 0xff,
es8389_init() is called instead of es8389_set_bias_level(..., SND_SOC_BIAS_ON).

Does this result in writing to the codec registers without the master clock
enabled, and leaving the master clock permanently disabled after the resume
completes?

[Severity: High]
This is a pre-existing issue, but since you are updating the volatile
register logic here, could this default-to-true behavior cause problems
during system resume?

Critical configuration registers like ES8389_DMIC_EN and ES8389_ADC_MODE
(managed by the 'ADC MUX' user kcontrol), as well as format registers
configured by es8389_set_dai_fmt() (e.g., ES8389_ADC_FORMAT_MUTE and
ES8389_DAC_FORMAT_MUTE), are not explicitly listed in this switch statement.

Because they fall through to this default case, they are marked as
volatile and bypass the regmap cache. When the system resumes from
suspend, regcache_sync() will not restore these registers.

If the codec resets these registers to hardware defaults upon resuming,
won't user-selected mux configurations and DAI formats be permanently
lost, potentially breaking the audio path?

[Severity: High]
This is a pre-existing issue, but modifying this table highlights a bug
in get_coeff() that affects how these entries are matched.

Does the bitwise logic in get_coeff() incorrectly treat dmic_sel=0 and
dvdd_vol=0 as wildcards?

sound/soc/codecs/es8389.c:get_coeff() {
    ...
    vddd_det |= ~(coeff_div[i].dvdd_vol % 2) & 0x01;
    dmic_det |= ~(coeff_div[i].dmic_sel % 2) & 0x01;

    if (vddd_det && dmic_det)
        return i;
    ...
}

This unconditionally evaluates to 1 when dmic_sel or dvdd_vol is 0,
turning 0 into a wildcard instead of an exact match. This can shadow
specific clock configurations and render subsequent array entries with the
same rate/mclk unreachable.

[Severity: High]
This is a pre-existing issue, but could we fix a regulator reference leak
on component removal?

In es8389_probe(), regulators are retrieved and manually enabled, but the
corresponding es8389_remove() component teardown function does not disable
them:

sound/soc/codecs/es8389.c:es8389_remove() {
    struct es8389_private *es8389 = snd_soc_component_get_drvdata(component);
    ...
    regmap_write(es8389->regmap, ES8389_ISO_CTL, 0xC1);
    regmap_write(es8389->regmap, ES8389_PULL_DOWN, 0x00);
}

Does this leak the regulator references when the I2C driver is unbound or
the module is removed?

[Severity: High]
This is a pre-existing issue, but does this code use uninitialized memory
if regmap_read() fails?

sound/soc/codecs/es8389.c:es8389_pcm_hw_params() {
    ...
    regmap_read(es8389->regmap, ES8389_DMIC_EN, &regv);
    dmic_enable = regv >> 7 & 0x01;
    ...
}

The return value of regmap_read() is ignored. If the I2C read fails,
regv contains uninitialized stack memory, causing dmic_enable to be randomly
set and potentially leading to invalid clock configurations.

[Severity: High]
This is a pre-existing issue, but does this code use uninitialized memory
if regmap_read() fails upon resuming?

sound/soc/codecs/es8389.c:es8389_resume() {
    ...
    regmap_read(es8389->regmap, ES8389_RESET, &regv);
    regcache_cache_bypass(es8389->regmap, false);

    if (regv == 0xff)
    ...
}

Similar to hw_params, if the hardware is unresponsive and the read fails,
regv contains uninitialized stack memory, potentially causing unpredictable
branching.

[Severity: High]
This is a pre-existing issue, but does es8389_pcm_hw_params() silently ignore
missing clock coefficients?

sound/soc/codecs/es8389.c:es8389_pcm_hw_params() {
    ...
    } else {
        dev_warn(component->dev, "Clock coefficients do not match");
    }

    return 0;
}

If get_coeff() fails to find a valid clock configuration, this function logs a
warning but still returns 0 (success). Can this mislead the ALSA core into
running audio with a misconfigured codec clock tree?

[Severity: High]
Does this change break the devicetree ABI?

In es8389_probe(), the driver reads the "everest,mclk-src" devicetree property
directly into the es8389->mclk_src variable:

sound/soc/codecs/es8389.c:es8389_probe() {
    ...
    ret = device_property_read_u8(component->dev, "everest,mclk-src", 
                                  &es8389->mclk_src);
    ...
}

Since ES8389_SCLK_PIN is redefined below as (1 << 6), any existing device
trees using logical values like <0> or <1> will fail this equality check.
This will silently bypass the SCLK configuration and break audio functionality,
unless device tree authors now populate the property with the raw hardware
bitmask <64>.
