This looks basically OK but there's a *lot* of weird coding style issues
in here. It's really all that, nothing too serious that I noticed -
I've pointed out some of the patterns below not every individual issue.
+ for (i = 0; i < ARRAY_SIZE(mic_gain_table); i++) {
+ if ((mic_gain_table[i].dgain == dgain_val)
+ && (mic_gain_table[i].scale == scale_val))
+ ucontrol->value.integer.value[0] = i;
+ }
This indentation is really weird, why is the && aligned with the if?
Accept.
+ snd_soc_update_bits(codec, PDMIC_DSPR1,
+ PDMIC_DSPR1_OFFSET_MASK,
+ (u32)(dd->pdata->mic_offset << PDMIC_DSPR1_OFFSET_SHIFT));
These are weird too, I'd expect the second line to be part of the first.
+static struct regmap *atmel_pdmic_codec_get_remap(struct device *dev)
+{
+ return dev_get_regmap(dev, NULL);
+}
This is (or should be) the default in the core.
You are right. The core has initialized the regmap in function
snd_soc_component_add_unlocked.
This function can be removed.
Thank you.

+ dev_err(codec->dev,
+ "sample rate is %dHz, min rate is %dHz, max rate is %dHz\n",
+ fs, rate_min, rate_max);
This too, alignment after the (.
Accept.
+ if (bits == 16)
+ dspr0_val = (PDMIC_DSPR0_SIZE_16_BITS

+ else if (bits == 32)
+ dspr0_val = (PDMIC_DSPR0_SIZE_32_BITS
+ << PDMIC_DSPR0_SIZE_SHIFT);
+ else
+ return -EINVAL;
This looks like it should be a switch statement.
Accept.
