STRUCT CLK_SI544_MULDIV(9)

💅 NAME 💅

struct clk_si544_muldiv — the multiplier/divider settings, bestie. that's it, that's the whole vibe ✨

this is a page from the Kernel API Manual, and honestly it's giving "small struct, big responsibilities" 🎀

🌸 SYNOPSIS 🌸

okay so here's the actual shape of it, no cap, copy it exactly:

struct clk_si544_muldiv {
    u32 fb_div_frac;
    u16 fb_div_int;
    u16 hs_div;
    u8 ls_div_bits;
    s32 delta_m;
    u32 xo_freq;
 };

🦋 Members 🦋

• fb_div_frac — the integer part of the feedback divider, and it's a whole 32 bits wide 👑 (yes, int part in the _frac field, that's literally what the page says, i don't make the rules 💀)
• fb_div_int — the fractional part of the feedback divider, 11 bits, living its best life 🙈 (and yeah, it's the frac one that's the integer — iconic chaos, we move)
• hs_div — the 1st divider. valid range is 5..2046, and lowkey important: it must be even when >33 ⚠️
• ls_div_bits — the 2nd divider, expressed as 2^x, range 0..5. and here's the vibe check: if ls_div_bits is non-zero, then hs_div must be even 🫶
• delta_m — the frequency shift for small -950..+950 ppm changes, 24 bit. tiny adjustments only, she's delicate 🧚

also xo_freq is right there in the struct, a whole u32 of it — the page doesn't hand it a description, so i'm not gonna make one up for you, iykyk 🤷‍♀️

and that's the whole page, periodt 💖 this little gem came to you from ./drivers/clk, dated October 2026, in the Kernel API Manual — mwah, go compile something gorgeous 🌈💅
