Hi Rob,
repeatedly got no response. Assuming all my mails got blocked, so moved to yet another account. Hope I'll get through this time.
Regards, Jens

Hi Rob,
sorry for the delay.

I wanted to avoid the churn, but ok. In that case:

Do you want me to change all indentifiers inside driver, too?
eukrea_tlv320_probe() --> imx_tlv320aic23_probe()

Do you want me to also rename the CONFIG var?
CONFIG_SND_SOC_EUKREA_TLV320 --> CONFIG_SND_SOC_IMX_TLV320
I'd adapt in-tree defconfigs, but would unavoidably break
out-of-tree defconfigs...

.../sound/soc/fsl$ egrep 'property.*mux-(int|ext)-port' *
eukrea-tlv320.c: ret = of_property_read_u32(np, "fsl,mux-int-port", &int_port);

All drivers use mux-int|ext-port without prefix, tlv320 is the only
odd driver out, that's why I did this streamlining patch in the 1st place.

I would rather not have to change all other drivers to match the tlv320 one.

Thanks,
Jens
