clk_set_rate_exclusive(9)

🌸 NAME 🌸

clk_set_rate_exclusive — set the clock rate and claim exclusivity over clock source. This is the clk_set_rate_exclusive(9) page from the Kernel API Manual, hiii bestie 💖

✨ SYNOPSIS ✨

okay so the signature is literally:

int clk_set_rate_exclusive (struct clk *clk , unsigned long rate );

🎀 ARGUMENTS 🎀

• clk — clock source. that’s the clock we’re talking about 👑
• rate — desired clock rate in Hz. yes, Hertz, not vibes ✨

💅 DESCRIPTION 💅

okay so this helper function lets drivers atomically set the rate of a producer and claim exclusivity over the rate control of the producer. it’s giving “I’m the main character of this clock’s rate now” 💅

It is essentially a combination of clk_set_rate and clk_rate_exclusite_get — and yes, that spelling is exactly what the page says, no cap, I’m not editing it fr fr 😭

bestie, the caller must balance this call with a call to clk_rate_exclusive_put. do not leave it hanging, okay? 💀

It returns success (0) or a negative errno. periodt 🫶
