STRUCT ICE_TSPLL_PARAMS_E82X(9)

💖 NAME 💖

struct ice_tspll_params_e82x — the E82X TSPLL parameters, bestie. That's it, that's the whole vibe ✨ (like, it's a struct, in the Kernel API Manual, and it's iconic)

---

🌸 SYNOPSIS 🌸

okay so picture this: one struct, four members, zero drama. here's exactly what it looks like, copy it character for character or don't come to my birthday party 🎀

struct ice_tspll_params_e82x {
    u8 refclk_pre_div;
    u8 post_pll_div;
    u8 feedback_div;
    u32 frac_n_div;
 };

she's small, she's cozy, she's literally carrying PLL configuration on her back 💅

🦋 Members 🦋

ngl this is the part where you actually read the field names — do it, i'm watching 👀

• refclk_pre_div — the Reference clock pre-divisor, no cap 🕰️ it does exactly what it says on the tin
• post_pll_div — the Post PLL divisor 💫 post-PLL, so it's doing its thing after the PLL, iykyk
• feedback_div — the Feedback divisor 🔁 feed it back, that's the whole job
• frac_n_div — the Fractional divisor 🍰 fractional, she's not a whole number and that's valid

🔥 Description 🔥

so here's the tea: these are Clock Generation Unit parameters, used to program the PLL based on the selected TIME_REF/TCXO frequency ⚡ that's literally it — clock gen vibes, PLL programming, frequency-dependent, main character energy 👑

like, this struct doesn't have opinions, she just holds the numbers the PLL needs. simple. slay. periodt 💜

if you want the rest of the story (and you do), go look at the Kernel file:

🫶 little reminder bestie: this is a struct definition, so all the usual "don't guess at behaviour" rules apply — the facts above are the facts, nothing more 💖
