rt5677_sel_asrc_clk_src(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the rt5677_sel_asrc_clk_src(9) page from the Kernel API Manual ✨ we’re about to make ASRC clock-source selecting make sense, no cap 💅

🎀 NAME 🎀

rt5677_sel_asrc_clk_src — picks the ASRC clock source for a whole set of filters 🎚️✨

🧚 SYNOPSIS 🧚

int rt5677_sel_asrc_clk_src (struct snd_soc_component *component ,
unsigned int filter_mask , unsigned int clk_src );

🌸 ARGUMENTS 🌸

  • component — the SoC audio component device 🎧
  • filter_mask — the mask of filters 🎛️
  • clk_src — the clock source ⏰

💖 DESCRIPTION 💖

okay so the ASRC function is literally for asynchronous MCLK and LRCK 🫶

real talk: since RT5677 can only support standard 32fs or 64fs i2s format, ASRC should be enabled to support special i2s clock format such as Intel's 100fs(100 * sampling rate) 😭

the ASRC function will track i2s clock and generate a corresponding system clock for codec 🌈

and this function? it provides an API to select the clock source for a set of filters specified by the mask 🎯 and the codec driver will turn on ASRC for these filters if ASRC is selected as their clock source 👑
