ASoC: soc-pcm: DPCM cares BE format
Current DPCM is caring only FE format. but it will be no sound if FE/BE was below style, and user selects S24_LE format. FE: S16_LE/S24_LE BE: S16_LE DPCM can rewrite the format, so basically we don't want to constrain with the BE constraints. But sometimes it will be trouble. This patch adds new .dpcm_merged_format on struct snd_soc_dai_link. DPCM will use FE / BE merged format if .struct snd_soc_dai_link has it. We can have other .dpcm_merged_xxx in the future .dpcm_merged_foramt .dpcm_merged_rate .dpcm_merged_chan Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Keita Kobayashi <keita.kobayashi.ym@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
