twl6040 have two vibra output drivers. They can be operated with audio stream coming through the PDM interface (fifth channel). The vibra outputs can be controlled via the input/FF driver as well. Selection between the two mode is implemented within the codec driver, the input/FF driver can only operate if the routing is set to "Input FF". Changing from "Input FF" to "Audio PDM" mode is protected as well: The switchin can only be done, if there is no running effect from the input/FF.
