💅 fsl_asoc_reparent_pll_clocks(9) — Kernel API Manual, bestie edition 🎀

okay so picture this: you're deep in the Kernel API Manual, section 9, and you've found the page for fsl_asoc_reparent_pll_clocks — yes the header truncates it to fsl_asoc_rep...t_pll_clocks(9) because even manpage headers need a little drama 💀 — and honestly? she's short, she's sweet, she's a one-job icon.

✨ NAME ✨

fsl_asoc_reparent_pll_clocks — set clock parent if necessary 🕰️💖

like, if necessary. she's not out here reparenting for fun. she checks first. main character energy but make it responsible.

🌸 SYNOPSIS 🌸

void fsl_asoc_reparent_pll_clocks (struct device *dev , struct clk *clk
, struct clk *pll8k_clk , struct clk *pll11k_clk , u64 ratio );

no return value, she just does it 🫶 returns void, so don't go looking for a status code, she's not giving you one.

🦋 ARGUMENTS 🦋

  • dev — device pointer. the device in question, your main character 📱
  • clk — root clock pointer. this is the one whose parent is getting switched up 👑
  • pll8k_clk — PLL clock pointer for 8kHz. the 8k girlie 🎧
  • pll11k_clk — PLL clock pointer for 11kHz. and her 11k bestie 🎶
  • ratio — target frequency for root clock. literally the whole reason we're here, it's the vibe check that decides everything ✨

🔥 DESCRIPTION 🔥

So what does she actually do? This function set root clock parent according to the target ratio. that's it. that's the whole thing 💅

she looks at the target ratio, looks at the root clock clk, and hooks it up to the right parent — and she's got both pll8k_clk (8kHz) and pll11k_clk (11kHz) sitting there ready to be the parent, so like… the math is mathing 🔥

no cap, it's a tiny function with a tiny job and she ate. periodt.

lowkey a reminder: the names, types and signature up there are exact — struct device *dev, struct clk *clk, struct clk *pll8k_clk, struct clk *pll11k_clk, u64 ratio — so copy them character for character when you call her 🙈
