💖 __prci_wrpll_pack(9) 💖

okay so bestie, this page is from the Kernel API Manual and it's all about one lil function that packs up your WRPLL config into a register value. it's giving kernel-clock realness, fr fr. 🌸

✨ NAME ✨

__prci_wrpll_pack — pack PLL configuration parameters into a register value 💅

💫 SYNOPSIS 💫

u32 __prci_wrpll_pack (const struct wrpll_cfg *c );

🎀 ARGUMENTS 🎀

• c — pointer to a struct wrpll_cfg record containing the PLL's cfg. this pointer is lowkey the main character here, no cap. 🫶

🦋 DESCRIPTION 🦋

Using a set of WRPLL configuration values pointed to by c, this function assembles a PRCI PLL configuration register value and returns it to the caller. literally the whole glow-up: config goes in, register value comes out. ✨

🌈 CONTEXT 🌈

Any context. 🫶

bestie, the caller must ensure that the contents of the record pointed to by c do not change during the execution of this function. like, do not let it shift mid-function, okay? 😭

👑 RETURN 👑

a value suitable for writing into a PRCI PLL configuration register. periodt. 💅
