aio_port_set_rate(9)

✨ aio_port_set_rate(9) ✨

okay bestie, so this is a Kernel API Manual page, and it's literally about setting the sampling rate of LPCM. it's giving "small function, big responsibilities" energy 💅

---

🌸 NAME 🌸

aio_port_set_rate — set sampling rate of LPCM

🎀 SYNOPSIS 🎀

int aio_port_set_rate (struct uniphier_aio_sub *sub , int rate );

🦋 ARGUMENTS 🦋

• sub — the AIO substream pointer, PCM substream only 🫶 (like, don't come at it with anything else, it said what it said)
• rate — Sampling rate in Hz. the actual number, bestie 🎵

💖 DESCRIPTION 💖

okay so what this does: it sets the suitable I2S format settings to the input/output port block of AIO. that's the whole vibe. ✨

and the parameter? it's specified by hw_params. so that's where it comes from, no cap.

⚠️ heads up: this function may return error if non-PCM substream. so if you're rolling up with something that isn't PCM, it might just say no 🙈

🔥 RETURN 🔥

Zero if successful, otherwise a negative value on error. that's it, that's the deal 💀
