Hi,
This patch series support for the channel selection (stereo/left/right) based on device tree bindings.
It also adds some registers defines and cleans up weird test on function exit.
Raphael Poggi (4):
sound: codecs: pcm1792a: clean function exit
sound: codecs: pcm1792a: add define for register
dt-bindings: sound: add binding for pcm1792a
sound: codecs: pcm1792a: introduce channel side

If so, we have two differents "problems", one at hardware level design because monaural mode requires two DACs, and an another one at software level "channel inversion". I have always thought that hardware description should be in dts, that's why I implement monaural mode using dts.

I have always thought that hardware description should be in dts, that's why I implement monaural mode using dts. Honestly, I don't know what is the best solution between "this is a hardware design, it should be in dts and shouldn't change" vs "this should be an alsa controler because we want extra features independent from hardware design" Raphaël >>>> return snd_soc_register_codec(&spi->dev, >>>> &soc_codec_dev_pcm1792a, &pcm1792a_dai, 1); >>>> } >>>> -- >>>> 2.1.0 >>>> >>>> _______________________________________________ >>>> Alsa-devel mailing list >>>> Alsa-devel-K7yf7f+aM1XWsZ/bQMPhNw@public.gmane.org >>>> http://mailman.alsa-project.org/mailman/listinfo/alsa-devel >>> >>> >>> >>> -- >>> | Michael Nazzareno Trimarchi Amarula Solutions BV | >>> | COO - Founder Cruquiuskade 47 | >>> | +31(0)851119172 Amsterdam 1018 AM NL | >>> | [`as] http://www.amarulasolutions.com | >>> -- >>> To unsubscribe from this list: send the line "unsubscribe linux-kernel" in >>> the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org >>> More majordomo info at http://vger.kernel.org/majordomo-info.html >>> Please read the FAQ at http://www.tux.org/lkml/ > > > > -- > | Michael Nazzareno Trimarchi Amarula Solutions BV | > | COO - Founder Cruquiuskade 47 | > | +31(0)851119172 Amsterdam 1018 AM NL | > | [`as] http://www.amarulasolutions.com | > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 23+ messages in thread

Basically you can get the same result restore some alsa config that match your topology. Even if you have two mono amplifier you can have the situation that you want to invert channel left and right and this can be done easily just reconfigure one as mono left and the other as mono right or write your own sound card that do in one control, change both together.
