💖 prcmu_config_clkout(9) 💖

okay bestie, welcome to the Kernel API Manual page for prcmu_config_clkout — clock-output configuration, but make it cute ✨

✨ NAME ✨

prcmu_config_clkout — configure one of the programmable clock outputs.

🌸 SYNOPSIS 🌸

int prcmu_config_clkout (u8 clkout , u8 source , u8 div );

🦋 ARGUMENTS 🦋

• clkout — the CLKOUT number, and it’s literally only 0 or 1 👑
• source — the clock to be used, one of the PRCMU_CLKSRC_* crew 💅
• div — the divider to be applied.

🔥 DESCRIPTION 🔥

So this function configures one of the programmable clock outputs (CLKOUTs). For div, keep it in the range [1,63] when you’re requesting a configuration, or set it to 0 to inform that the configuration is no longer requested. That’s the whole vibe check, no cap 🫶
