[PATCH 1/3] bytcr-rt5640: Fix DMIC1 not working when connected over AIF2

[Jaroslav Kysela]

Dne 08. 06. 20 v 22:21 Hans de Goede napsal(a):
> The RT5640 codec has 2 ADC-s which are caled the Stereo ADC and the
> Mono ADC (even though the mono ADC seems to be stereo too?). The Stereo
> ADC is connected to the AIF1 interface of the codec and the Mono ADC
> to the AIF2 interface.
> 
> Almost all X86 BYT/CHT design use the AIF1 interface, but a few models
> use the AIF2 interface. For this reason the IN?-InternalMic.conf bits
> not only select/enable the microphone input on the Stereo ADC, but
> also on the Mono ADC, so that the analog mic. inputs also work in devices
> using the AIF2 interface.
> 
> Before this commit DigitalMics.conf was only setting up the DMIC input
> on the Stereo ADC and not on the Mono ADC, causing DMIC1 to not work
> when connected over AIF2.
> 
> This commit adds selecting / enabling DMIC1 on the Mono ADC.
> This fixes the internal microphone not working on the Toshiba Encore WT10A.
> 
> Note that for devices which use the AIF1 interface this is a no-op since
> the AIF1 interface is not connected to anything, there is no complete
> chain so DAPM will not enable any of the elements in the chain.
