💅 devm_clk_hw_register_divider_table

okay so this little icon is straight out of the Kernel API Manual, and it's the devres glow-up of "register a table based divider clock with the clock framework." bestie, that's the whole vibe: it's a clock divider, but the lookup table kind, and it's managed for you. 🫶

🎀 NAME 🎀

devm_clk_hw_register_divider_table — register a table based divider clock with the clock framework (devres variant). that's it, that's the function. devres variant means it's the one that cleans up after itself, iykyk. ✨

🌸 SYNOPSIS 🌸

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

ten arguments. yes ten. don't panic, we're going through every single one 💅

💖 ARGUMENTS 💖

  • dev — the device that's registering this clock. like, whose house is this clock living in 🏠
  • name — name of this clock. give it a cute one, it deserves it ✨
  • parent_name — name of clock's parent. every main character has an origin story 🌈
  • flags — framework-specific flags. the framework's rules, not ours 🎀
  • reg — register address to adjust divider. this is where the divider actually lives 🔥
  • shift — number of bits to shift the bitfield. slide to the left, slide to the right 💃
  • width — width of the bitfield. how many bits we're working with, periodt
  • clk_divider_flags — divider-specific flags for this clock. different flag set, different vibe check 💅
  • table — array of divider/value pairs ending with a div set to 0. ⚠️ that trailing zero is the terminator bestie — it's how the code knows the list is done, so don't be out here forgetting it 😭
  • lock — shared register lock for this clock. sharing is caring, and also prevents chaos 🔒

👑 SEE ALSO 👑

okay this list is long and it ate, so let's give it the respect it deserves — the kernel file these live in is ./include/linux/clk-provider.h, and it's giving main character energy. go read all of these, fr fr 🦋

💀 reminder: that table has to be terminated with a div of 0, or the whole thing goes off the rails. no cap, that's the one thing that will bite you.

that's the whole page bestie, you're so welcome 💜 and for the credits moment: this one lives under ./include/linux, dated October 2026 — those are the source/version and date sending their love from the footer. mwah 🎀✨
