No, this is actually supported now - to expand on what Liam said in
reply to Peter if you leave the stream NULL in your DAC widgets and
instead use a SND_SOC_DAPM_AIF_IN() to bind to the stream then you can
add any DAPM routing you need between the AIF and the DAC. The WM8994
driver is one example of doing this, it has digital mixing and routing
support which allows audio paths that never reach a DAC.
