devm_clk_bu..._all_enabled(9)

✨ devm_clk_bulk_get_all_enabled ✨

okay bestie so this is a page from the Kernel API Manual and it's about one (1) extremely helpful little function. buckle up, it's lowkey iconic 💅

---

🌸 NAME 🌸

devm_clk_bulk_get_all_enabled — get and enable all the clocks of the consumer, and do it managed, periodt 🎀

---

🦋 SYNOPSIS 🦋

int devm_clk_bulk_get_all_enabled (struct device *dev , struct
clk_bulk_data **clks );

like literally that's it, that's the whole signature, she's compact 👑

---

💖 ARGUMENTS 💖

• dev — the device that's being the clock "consumer" here (yes, that's the actual word they use, it's giving very main character energy 🙈)
• clks — a pointer to the consumer's clk_bulk_data table 🗂️

---

🧚 DESCRIPTION 🧚

okay so here's the tea ☕ — the return value is doing a little bit of everything:

• returns a positive value = that's the number of clocks obtained, and the clock references get stored in the clk_bulk_data table in the clks field 🎉
• returns 0 if there're none at all — like nobody showed up to the party 😭
• returns a negative value if something failed — code red, something went wrong 💀

This helper function lets drivers get all the clocks of the consumer and enable them in one single operation, with management included, no cap 🫶

The clks will automatically be disabled and freed when the device is unbound — like she cleans up after herself, we stan a responsible icon ✨

ngl if your driver is juggling a whole squad of clocks and you don't wanna babysit each one, this is your girl 💅

that's the whole page bestie, love u, see u in the next one 🫶💖 this one lives in ./include/linux and it's dated October 2026 — mwah, bye! 🎀✨
