devm_clk_rate_exclusive_get(9)

💅 devm_clk_rate_exclusive_get(9) — bestie clock edition 💅

okay so we’re in the Kernel API Manual, and the star of this page is devm_clk_rate_exclusive_get(9). It’s giving managed clock exclusivity, and yes bestie, we’re getting into every single detail. ✨

🌸 NAME 🌸

devm_clk_rate_exclusive_get — the devm variant of clk_rate_exclusive_get. periodt.

🎀 SYNOPSIS 🎀

int devm_clk_rate_exclusive_get (struct device *dev , struct clk *clk );

🦋 ARGUMENTS 🦋

• dev — device the exclusivity is bound to. This is the device anchor, bestie.
• clk — clock source. The clock in question. iconic.

💖 DESCRIPTION 💖

Calls clk_rate_exclusive_get on clk and registers a devm cleanup handler on dev to call clk_rate_exclusive_put.

🚨 Important, no cap: must not be called from within atomic context. Like, do not. That is the vibe check and it is a hard pass.
