In kernel `soc-dai.h`, DAI clock gating is defined as following:
~~~~ #define SND_SOC_DAIFMT_CONT (1 << 4) /* continuous clock */ #define SND_SOC_DAIFMT_GATED (0 << 4) /* clock is gated */ ~~~~
Therefore, the corresponding field of struct snd_soc_tplg_hw_config should be inverted compared to the current logic:
clock_count = 1 => SND_SOC_DAIFMT_CONT clock_count = 0 => SND_SOC_DAIFMT_GATED
