clk_bulk_get(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, you're looking at the Kernel API Manual page for clk_bulk_get 💅 — it's literally the "grab a whole squad of clock consumers in one shot" helper. Let's get into it 🫶

✨ NAME ✨

clk_bulk_get — lookup and obtain a number of references to clock producer. 👑

🌸 SYNOPSIS 🌸

int clk_bulk_get (struct device *dev , int num_clks , struct clk_bulk_data *clks );

🎀 ARGUMENTS 🎀

  • dev — device for clock "consumer" 😌
  • num_clks — the number of clk_bulk_data
  • clks — the clk_bulk_data table of consumer

💅 DESCRIPTION 💅

This helper function lets drivers get several clk consumers in one operation. Iconic. ✨

If any of the clk cannot be acquired, then any clks that were obtained will be freed before returning to the caller. No leaked refs, periodt. 💖

It returns 0 if all clocks specified in clk_bulk_data table are obtained successfully, or valid IS_ERR condition containing errno. The implementation uses dev and clk_bulk_data.id to determine the clock consumer, and thereby the clock producer. The clock returned is stored in each clk_bulk_data.clk field. Ngl that's the whole mapping vibe. 🦋

Drivers must assume that the clock source is not enabled. 🚨

clk_bulk_get should not be called from within interrupt context. Like, do not do it, bestie 😭
