The simple-card can be used as combining card driver to add the jacks, no new one is required. Create a jack (for input-events) for jack devices in the auxiliary device list (aux_devs). A device which has the functions set_jack and get_jack_supported_type counts as jack device. Add a devicetree entry, in case not all input types are required. simple-card,aux-jack-types: Array of snd_jack_type to create jack-input-event for jack devices in aux-devs. If the setting is 0, the supported type of the device is used.
