Subject[PATCH] ASoC: fsl-asoc-card: Add snd_soc_of_parse_audio_routing()
Date
This patch adds snd_soc_of_parse_audio_routing() to get dapm routes
via Device Tree. Because snd_soc_of_parse_audio_routing() overrides
dpam_routes, we use snd_soc_dapm_add_routes() to append the original
build-in DPCM routes instead of linking them to dpam_routes directly.
