These and some of the other registers sound like volatile registers which shouldn't have defaults since they shouldn't be in the cache at all but rather read from the device - and you do in fact have a function marking them as volatile further down.

You had error checking on sysclk in hw_params(), it'd bet better to do that here too so people can tell they set a bad clock before they start a stream.

You should do this check in the I2C level probe. The error message is also wrong if the register does read but isn't what we expected.
Are you *sure* no new revisions of the device will be made?

Sounds like this might be the I2S vs left justified configuration?

This seems a bit magic numberish (what are 0 and 1 here?).
answer below
+static const struct soc_enum max98926_global_enum[] = {
SOC_ENUM_SINGLE_EXT(ARRAY_SIZE(pdm_text), pdm_text),
+};
Not sure what this control is supposed to do?
answer below
SOC_ENUM("Input Sel", max98926_input_sel),
SOC_ENUM("DAI Input Sel", max98926_dai_input_sel),
These look like DAPM controls?
'Input Sel' is basically as below: DAC Input Select Selects the left, right or mix of left + right as the DAC input signal. 00 = Left DAI input (default) 01 = Right DAI input 10 = Left + Right 11 = Left/2 + Right/2 So i think it is best that it is not part of dapm.
'DAI Input Sel' is the input to the power amplifier. 98926 amplifier can take PCM input from I2S or can take analog signal. So we need to set this as control.
SOC_ENUM_EXT("PDM CH0 Enable", max98926_global_enum[0],
max98926_get_pdm_ch_zero, max98926_put_pdm_ch_zero),
SOC_ENUM_EXT("PDM CH1 Enable", max98926_global_enum[0],
max98926_get_pdm_ch_one, max98926_put_pdm_ch_one),
We can get vi feedback in two channels. Customer can enable either channel 0 or channel 1. Channel 0 source can be voltage or current. So basically i created kcontrol for that so that we can either enable channel 0, 1 or both.
'PDM CH0 Enable' 1 causes channel 0 to be enabled for current. So i enable all the relevant bit in put callback.
There's two different controls mapping to one element of an array?
+static void max98926_set_sense_data(struct max98926_priv *max98926) +{
if (max98926->intrleave_mode) {
interleave.
switch (fmt & SND_SOC_DAIFMT_MASTER_MASK) {
case SND_SOC_DAIFMT_CBS_CFS:
max98926_set_sense_data(max98926);
break;
case SND_SOC_DAIFMT_CBM_CFM:
case SND_SOC_DAIFMT_CBS_CFM:
case SND_SOC_DAIFMT_CBM_CFS:
default:
dev_err(codec->dev, "DAI clock mode unsupported");
return -EINVAL;
No need to list all the formats you don't support.
}
switch (fmt & SND_SOC_DAIFMT_FORMAT_MASK) {
case SND_SOC_DAIFMT_I2S:
case SND_SOC_DAIFMT_LEFT_J:
break;
I'm not seeing anything that handles these diffeerently, they are different formats so you should only list whichever one is actually supported.
default:
dev_dbg(codec->dev, "format unsupported %d",
params_format(params));
return -EINVAL;
}
return max98926_set_clock(max98926, params);
May as well just inline set_clock() here - this appears to be the only place it's used.
+static int max98926_dai_set_sysclk(struct snd_soc_dai *dai,
int clk_id, unsigned int freq, int dir)
+{
struct snd_soc_codec *codec = dai->codec;
struct max98926_priv *max98926 = snd_soc_codec_get_drvdata(codec);
max98926->sysclk = freq;
return 0;
+}
You had error checking on sysclk in hw_params(), it'd bet better to do that here too so people can tell they set a bad clock before they start a stream.
ret = regmap_read(max98926->regmap,
MAX98926_VERSION, ®);
if ((ret < 0) ||
((reg != MAX98926_CHIP_VERSION) &&
(reg != MAX98926_CHIP_VERSION1))) {
dev_err(codec->dev, "Failed to read: %x\n", reg);
return -EINVAL;
}
You should do this check in the I2C level probe. The error message is also wrong if the register does read but isn't what we expected.
Are you *sure* no new revisions of the device will be made?
yes will remove the revision check as we have few revisions planned.
/* It's not the default but we need to set DAI_DLY */
regmap_write(max98926->regmap,
MAX98926_FORMAT, MAX98926_DAI_DLY_MASK);
Sounds like this might be the I2S vs left justified configuration?
basically it is dai data delay. Setting this way causes the MSB to be valid on second active edge after LRCLK event.

Sure, but it looks like a DAPM control.

The user needs to be able to tell all this from the controls, it doesn't seem that hard - it sounds like you want to have SIGGEN widgets for the measurements and then route them to the capture DAI normally.

The driver should probably print the revision for diagnostics.

This should be part of setting the DAI format then.
