This commit adds a bare bones driver support for TLV320AIC31XX family

Applied, thanks. One thing it'd be good to fix:

+
+- gpio-reset - gpio pin number used for codec reset
+- ai31xx-micbias-vg - MicBias Voltage setting
This is optional but...
+ of_property_read_u32(np, "ai31xx-micbias-vg", &value);
+ switch (value) {
+ case MICBIAS_2_0V:
+ case MICBIAS_2_5V:
+ case MICBIAS_AVDDV:
+ aic31xx->pdata.micbias_vg = value;
+ break;
+ default:
+ dev_err(aic31xx->dev,
+ "Bad ai31xx-micbias-vg value %d DT\n",
+ value);
+ aic31xx->pdata.micbias_vg = MICBIAS_2_0V;
+ }
...you'll get an error if it's missing (and an uninitialised memory
read).
Actually you don't. The value-variable is initialized to MICBIAS_2_0V
and if "ai31xx-micbias-vg" is not present of_property_read_u32 leaves
the variable untouched, but I'll send a patch for fixing the unused
variable working shortly.
Forget about the v6 version of the patch.
Thanks,
Jyri
