STRUCT CLK_RCG(9)

💖 NAME 💖

struct clk_rcg — the root clock generator, and yes bestie it's exactly as main-character as it sounds 👑

okay so real quick before we dive in: this page is struct clk_rcg(9) from the Kernel API Manual, that's the title + the manual section, and it's all about this one struct. let's get into it 🫶

✨ SYNOPSIS ✨

struct clk_rcg {
    u32 ns_reg;
    u32 md_reg;
    struct mn       mn;
    struct pre_div  p;
    struct src_sel  s;
    const struct freq_tbl   *freq_tbl;
    struct clk_regmap       clkr;
 };

no cap, that's the whole shape of it. now let's do a vibe check on every single member, one by one, because we do not skip 💅

🎀 Members 🎀

• ns_reg — the NS register. that's it, that's the whole gig ✨
• md_reg — the MD register. iconic, separate register, separate slay 💜
• mn — the mn counter 🌀
• p — the pre divider. lowkey doing the dividing before the dividing 🌸
• s — the source selector. it picks where the source comes from, fr fr 🦋
• freq_tbl — the frequency table. pointer to const struct freq_tbl, and this is where the frequencies live 📊
• clkr — the regmap clock handle. the actual clock-y bit 🕐

ngl the member list is short but every one of them is carrying the whole struct on its back, no notes 💀

👑 SEE ALSO 👑

like literally the whole friend group right there 🧚

and that's the page!! 🎀 this came to you from ./drivers/clk/qcom, dated October 2026, and it's struct clk_rcg(9) obvi 💖 go be iconic with your root clock generator, bestie 🌈⭐
