ASoC: simple-card-utils: share asoc_simple_hw_param()
The difference between simple-card / audio-graph are just using OF graph style, or not. In other words, other things should be same. This means, simple-card/audio-graph common functions should be implemented at simple-card-utils, and its own functions should be implemented at each files. Current simple-card / audio-graph have almost same functions. This patch shares asoc_simple_hw_param() between in these 2 drivers. One note is that only simple-card supports simple_set_clk_rate() at hw_param from commit e9be4ffd4f40fcb ("ASoC: simple-card: set cpu dai clk in hw_params"). By this patch, audio-graph has same feature. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
