ASoC: add new simple-card-utils.c
Current ALSA SoC has simple-card driver which is supporting both platform and DT probe. Now, some sound cards driver are created based on simple-card. They have similar feature or function, but implemented separately on each drivers. This is a waste of code. OTOH, merging these driver into same driver is highly risk, because it will be very difficult to keep compatibility. More over, ALSA SoC want to have graph base of DT feature in the future. Maybe it want to use simple-card like feature / function. Because of these background, this patch creates simple-card helper utils, and provides common function to each drivers. 1st is asoc_simple_card_parse_daifmt() Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
