📦 version 7.3.1, in nixpkgs unstable

💅 clk_hw_register_divider

okay so bestie, welcome to the clk_hw_register_divider(9) page from the Kernel API Manual ✨ — this is the one where you tell the clock framework "hey, here's a divider clock, pls take care of it" 🎀

🌸 NAME 🌸

clk_hw_register_divider — register a divider clock with the clock framework 🕰️✨

🦋 SYNOPSIS 🦋

clk_hw_register_divider (dev , name , parent_name , flags , reg , shift
, width , clk_divider_flags , lock );

like, that's the whole call, no cap 💅

✨ ARGUMENTS ✨

okay so here's every single thing you gotta hand over, one by one 🫶

  • dev — the device that's registering this clock. it's giving "this is my clock, I'm its person" 💖
  • name — the name of this clock. yep, you gotta name it. main character energy 👑
  • parent_name — the name of the clock's parent. every icon needs an ancestor fr fr 🌈
  • flags — framework-specific flags. the vibe check parameters, if you will ⭐
  • reg — the register address to adjust the divider. this is where the actual bits live 🏠
  • shift — how many bits to shift the bitfield. slide to the left, slide to the right 💃
  • width — the width of the bitfield. how many bits wide this whole situation is 📏
  • clk_divider_flags — divider-specific flags for this clock. yes, there are two kinds of flags, don't @ me 🙈
  • lock — a shared register lock for this clock. sharing is caring, but like, thread-safely 🔒
ngl, if you mix up flags and clk_divider_flags that's a whole mood and also probably a bug. two different flag piles, bestie 💀
