clk_rcg2_split_div(9)

🌸 NAME 🌸

clk_rcg2_split_div — bestie, this is the split multiplier that just does not fit in n and doesn't fit in pre_div either 😭 so it gets split between the two, and honestly? iconic problem-solving 💅

This page lives in the Kernel API Manual, and it's all about that one little function doing the most.

✨ SYNOPSIS ✨

void clk_rcg2_split_div (int multiplier , unsigned int *pre_div , u16 *n
, unsigned int pre_div_max );

Notice it returns void — it's not giving you anything back, it's just doing its thing and editing your pointers in place. main character energy, fr fr 👑

🎀 ARGUMENTS 🎀

• multiplier — the multiplier that you're splitting between n and pre_div. This is the number that's too big for either one alone, so it has to share the load 🫶
• pre_div — a pointer to the pre divisor value. Yes, a pointer — so this function is gonna reach in and change it, no cap.
• n — a pointer to the n divisor value. Also getting written to. Two pointers, one function, zero survivors 💀
• pre_div_max — the pre divisor maximum value. Basically the ceiling for how much pre_div is allowed to take, so the split knows where to stop. 🔥

• Kernel file ./drivers/clk/qcom/clk-rcg2.c
• convert_to_reg_val(9)
• calc_rate(9)

Go read those too, they're literally in the same file and they're lowkey part of the whole story 🌈

ok that's the whole page bestie, no gatekeeping 💖 now go forth and split those multipliers correctly ✨

as always, this came from ./drivers/clk/qcom, it's part of the Kernel API Manual, and it's dated October 2026 — mwah, catch you on the next manpage 🎀💜
