As you already know, the vmmc driver expects some kernel commandline parameter which are neither set in the dts for your board nor passed by the bootloader of your board.

What we already know:

  * AVM uses a different solution for the VPE stuff
  * there is a different (no lantiq) SLIC on this board
  * the hardcoded GPIOs in the vmmc driver doesn't match the ones used by the dect SLIC on your board

Furthermore, there is no mention of the lantiq vmmc driver in the OEM firmware bootlog of your board.

As long as it isn't know how the voice stuff really works on your board, it doesn't make any sense to add the extra kernel commandline parameters. Might be that FXS port of your board requires some proprietary code, which makes it unlikely that it will ever work in LEDE. Might be that the vmmc isn't used at all with the AVM solution and might be incompatible.

I'm going to close this report as it isn't really a bug. It is rather a lack of informations how the AVM firmware handles the FXS port.
