[alsa-devel] [PATCH v2 7/9] ASoC: omap-abe-twl6040: Configure card according to platform data

[Peter Ujfalusi]

Disable the not connected pins on the board based on the
received platform data.
DO not register the jack function on boards, which does not have
means to detect it (jack is always connected).
