STRUCT CLK_DYN_RCG(9)

💅 struct clk_dyn_rcg(9) — the Kernel API Manual, bestie edition 🎀

okay so picture this: it's a page from the Kernel API Manual and it's literally all about struct clk_dyn_rcg. say it with me — root clock generator with glitch free mux. yes queen, glitch free. no messy transitions, no drama, the mux just switches and everything stays flawless. 💅✨

✨ NAME ✨

struct clk_dyn_rcg — root clock generator with glitch free mux 🕰️🦋

like, it's a root clock generator, and the mux? glitch free. that's the whole vibe. no cap.

🌸 SYNOPSIS 🌸

struct clk_dyn_rcg {
    u32 ns_reg[2];
    u32 md_reg[2];
    u32 bank_reg;
    u8 mux_sel_bit;
    struct mn       mn[2];
    struct pre_div  p[2];
    struct src_sel  s[2];
    const struct freq_tbl *freq_tbl;
    struct clk_regmap clkr;
 };

look at her. iconic struct. every field accounted for, nothing skipped, we respect the layout fr fr 🫶

💖 Members 💖

okay bestie, here's the member-by-member breakdown, and yes I'm gonna give each one its moment:

• ns_reg — the NS0 and NS1 register 👑 two of them, banked, living their best life.
• md_reg — the MD0 and MD1 register ✨ same deal, a whole pair.
• bank_reg — the register you XOR mux_sel_bit into to switch the glitch free mux 🔀 this is lowkey the main character of the switching situation.
• mux_sel_bit — the bit you XOR in to switch the glitch free mux 💅 tiny but powerful, honestly.
• mn — the mn counter, and it's banked 🎀 [2] of them, one per bank, as one does.
• s — the source selector, also banked 🌈 [2], matching energy.
• freq_tbl — the frequency table 📊 where the frequencies are, bestie.
• clkr — the regmap clock handle 🔥 the actual handle for the clock, slay.

ngl, p (the struct pre_div p[2]) is sitting right there in the struct too — the manual's member list doesn't say anything about it, so I'm not gonna invent lore. we simply acknowledge her presence 🫡

aaaand that's the page!! 💜 this cutie lives in ./drivers/clk/qcom and the date on it is October 2026 — so yeah, she's from the future, obviously, main character energy only. mwah, go forth and switch those muxes glitch-free, bestie 💖🎀🧚‍♀️
