psc_i2s_set_fmt(9)

💅 NAME

okay so this is psc_i2s_set_fmt(9) from the Kernel API Manual — and it is literally here to set the serial format. periodt 💖

✨ SYNOPSIS ✨

int psc_i2s_set_fmt (struct snd_soc_dai *cpu_dai , unsigned int format
);

🎀 ARGUMENTS 🎀

• cpu_dai — the DAI runtime data pointer, aka the little backstage pass for your DAI runtime info 🫶
• format — one of the SND_SOC_DAIFMT_xxx values, bestie; that's the whole format menu ✨

🦋 DESCRIPTION 🦋

so the machine driver calls this function to tell us what serial format to use. that's the whole vibe check 💅

and lowkey this driver is not flexible: it only supports I2S mode 🔥. if the format is not SND_SOC_DAIFMT_I2S, it returns an error. no cap.

🌸 RETURN 🌸

0 on success, or -EINVAL on failure. slay or fail, that's the whole story 😭
