Subject: [PATCH v1 4/4] ASoC: dt-bindings: simple-card: create jack for aux_devs

Add 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.
A device which has the functions set_jack and get_jack_supported_type
counts as jack device.
