💖 cs4270_hw_params(9) 💖

okay so bestie, this is the Kernel API Manual page for cs4270_hw_params(9). 🫶 Group-chat rundown time — cute vibe, same facts, no cap.

🌸 NAME 🌸

cs4270_hw_params — program the CS4270 with the given hardware parameters. periodt. 💅

✨ SYNOPSIS ✨

int cs4270_hw_params (struct snd_pcm_substream *substream , struct
snd_pcm_hw_params *params , struct snd_soc_dai *dai );

🎀 ARGUMENTS 🎀

• substream — the audio stream 🌊
• params — the hardware parameters to set ⚙️
• dai — the SOC DAI (ignored) 🙈 — literally ignored, so don't give it main character energy.

🔥 DESCRIPTION 🔥

This function programs the hardware with the values provided. Specifically? The sample rate and the data format. That's the whole vibe check. ✨

The .ops functions are used to provide board-specific data, like input frequencies, to this driver. This function takes that information, combines it with the hardware parameters provided, and programs the hardware accordingly. Obsessed with the teamwork, fr fr. 💖
