Subject: Re: [PATCH] subsystem: Amplifier driver for TAS5805M,Texas
 instruments

Hi Mark,

Yes, I agree that the code didn’t integrate with ALSA API,
and we only need to initialize i2c registers due to make the amplifier works properly,
and I do find there is already an amplifier driver in /drivers/iio/amplifier/,
that’s why I sent the patch to Jonathan,
I want to put this driver into /drivers/iio/amplifier/,
but he thought that this is an amplifier driver,
and we should put it into /sound/doc/codecs/,
so would you please give me an advice about the driver belongs to which subsystem?
Jonathan, what do you think?

Best Regards,
Leslie
