💖 fsl_esai_divisor_cal(9) 💖

okay so bestie, we're in the Kernel API Manual today and this little icon is from ./sound/soc/fsl — it's the divider math girlie for the ESAI and she is so ready to explain herself 🎀

✨ NAME ✨

fsl_esai_divisor_cal — literally the function that does the math for the divisors of psr, pm, fp 💅 and bestie she is supposed to be called inside set_dai_sysclk() and set_bclk(), okay? that's her whole assignment. no cap.

🌸 SYNOPSIS 🌸

int fsl_esai_divisor_cal (struct snd_soc_dai *dai , bool tx , u32 ratio
, bool usefp , u32 fp );

🦋 ARGUMENTS 🦋

• dai — pointer to DAI 🫶 she just needs the pointer bestie, that's it.
• tx — tells you if the current setting is for playback or for capture 👑
• ratio — the desired overall ratio for the participating dividers ✨ (and yes the original calls them "paticipating" dividers, we love a typo moment, keeping it exactly as it is 💀)
• usefp — for HCK setting there's literally no need to set the fp divider 🙈 so this flag exists for that
• fp — bypass other dividers by setting fp directly, but only if fp != 0 ⭐

🔥 SEE ALSO 🔥

• struct fsl_esai(9)
• fsl_esai_set_dai_sysclk(9)
• fsl_esai_set_bclk(9)

ngl bestie the whole vibe here is just "do the divider math, hand it back as an int, then go call her from set_dai_sysclk() and set_bclk()" — she's a supporting character with main character energy 🌈
