LM49352 kernel driver

Zoran Lukic

We are developing new device using LM49352 chip. Could you tell me please, do you have LM49352 driver for newer kernel?

In current kernel we could find only driver for LM49453, but not datasheet for that chip anywhere. It's an audio codec driver and on first glance very similar to LM49352. Is LM49453 yours chip or NS's, or ..?

On your forum there was a talk about this chip: TLV320AIC3120, to be the most similar and has a kernel driver  sound/soc/codecs/tvl320aic3x.c
Also, old driver on this forum for LM49352 is based on that ( tlv320aic3x.c ) driver.

Hi, Zoran,

Welcome to e2e, and thanks for your interest in our products!

You can find all our information about drivers on this post. Unfortunately, we don't have any drivers for the LM49352.

Hi Don,

Thank you for your answer, I already started work on driver.

Could you tell me about LM49453 chip, please? It says its yours (in codec c file http://lxr.free-electrons.com/source/sound/soc/codecs/lm49453.c ), but there is no trace of it on your web site:

Looking at registers its obvious that its not the same chip, but I am curious about it.

Best Regards,

Zoran

Hi, Zoran,

LM49453 is a custom part, and I am not allowed to disclose any information about it.
