I see the aux binding in soc-core.c
Where is an example of how to use it in a device tree?

None of these are used in a device tree that I can spot..
omap/rx51.c:static struct snd_soc_aux_dev rx51_aux_dev[] = {
omap/rx51.c: .aux_dev = rx51_aux_dev,
omap/rx51.c: .num_aux_devs = ARRAY_SIZE(rx51_aux_dev),
omap/rx51.c: rx51_aux_dev[0].codec_name = NULL;
omap/rx51.c: rx51_aux_dev[0].codec_of_node = dai_node;
samsung/speyside.c:static struct snd_soc_aux_dev speyside_aux_dev[] = {
samsung/speyside.c: .aux_dev = speyside_aux_dev,
samsung/speyside.c: .num_aux_devs = ARRAY_SIZE(speyside_aux_dev),
samsung/neo1973_wm8753.c:static struct snd_soc_aux_dev neo1973_aux_devs[] = {
samsung/neo1973_wm8753.c: .aux_dev = neo1973_aux_devs,
samsung/neo1973_wm8753.c: .num_aux_devs = ARRAY_SIZE(neo1973_aux_devs),
samsung/neo1973_wm8753.c: neo1973.num_aux_devs = 1;
