✨ NAME ✨

🌸 SYNOPSIS 🌸

int snd_soc_dai_set_pll (struct snd_soc_dai *dai , int pll_id , int
source , unsigned int freq_in , unsigned int freq_out );

like, look at that signature. it's giving "four args and a dream". no cap. ✨

🦋 ARGUMENTS 🦋

  • dai — the DAI. yes, THE DAI. main character energy, obviously. 👑
  • pll_id — the DAI specific PLL ID. which PLL are we talking about? this one. iykyk. 🔥
  • source — the DAI specific source for the PLL. where the PLL gets its vibe from. 🌈
  • freq_in — PLL input clock frequency in Hz. the going-in number. 💖
  • freq_out — requested PLL output clock frequency in Hz. the coming-out number, and it's the one you asked for. 🫶

💜 DESCRIPTION 💜

so what does it actually do? it configures and enables the PLL so it can generate an output clock based on the input clock. literally that's the whole thing — clock in, clock out, one PLL in the middle making it happen. ate. 🍓

no cap, that's all the page says, so that's all i'm gonna say. we don't make stuff up here. 🙈
